The Argentine attacker scored his 400th goal for the Catalan club but it was his overall contribution that helped his sluggish side secure a vital win over Valencia
The magnificent multi-tasker: Messi hits another milestone to drag tired Barca to victory
It was a fitting finaleLionel Messi made sure of victory over Valencia at Camp Nou on Saturday with his 400th goal for Barcelona, but ended up lying on the turf exhausted - just like the rest of his team-mates.

Barca took the lead after 55 seconds when Messi fed Luis Suarez and the Uruguay striker beat Diego Alves. But that was as good as it got in performance terms from the Blaugrana, who needed goalkeeper Claudio Bravo, the woodwork and some suspect finishing from Valencia to claim all three points.

"I have [former sporting director] Andoni Zubizarreta to thank for bringing in two great goalkeepers," Luis Enrique said after the match, in which Bravo had shone with several superb saves, most notably his fine stop to keep out Dani Parejo's penalty early on.

Luis Enrique's decision to play Javier Mascherano in midfield alongside Sergio Busquets handed the initiative to Valencia and, had it not been for the early Suarez strike, the outcome of the match may have been entirely different.

But the Barca boss rectified at half-time - to his credit - withdrawing the out-of-sorts Adriano, moving Mascherano back into the defence and introducing Ivan Rakitic in midfield. Still it was not classic Barca, but it was better and - in the end - it was good enough.

Luis Enrique said recently that performances do not matter now and he is correct. Three points from a fixture this side lost last season - sandwiched between two crucial Champions League games and with Andres Iniesta sidelined - made for a happy ending for the Catalan club this time around. At this stage of La Liga and with just a two-point lead over Madrid at the start of the day, a slip-up could have been extremely costly.

PUTTING THE HAMMER DOWN | Messi marks his latest milestone for Barcelona

And of course it was Messi, who had looked tired himself and missed a good chance in the first half, who dragged his side through this potential banana skin as he set up the first and scored the second in added time as Valencia threw men forward in a desperate attempt to draw level.

"Messi was supportive, just like the other attackers," Luis Enrique said. "They have done what we always ask of them. Leo showed again that he is more than goals. He worked hard today - both in defence and attack."

Indeed. And with Busquets and Mascherano making up a more combative than creative midfield alongside a frustrated Xavi, whose influence was restricted against a strong and physical rival, Messi's own impact in the middle was even more important. A number of vital interventions in his own half nullified the threat of Valencia even further and highlighted the Argentine's all-round efforts.

Barca have now taken four points from Sevilla away and Valencia at home - two tricky fixtures still left for title rivals Real Madrid in the coming weeks. These are tough tests for Carlo Ancelotti's side, especially if they remain in the Champions League by beating Atletico on Wednesday at the Santiago Bernabeu.

For Luis Enrique's men, however, it is another difficult match out of the way ahead of the next examination in La Liga: the Catalan derby away at Espanyol next weekend. And there is no rest or let-up before that one, either, as PSG visit Camp Nou in the sides' quarter-final second leg on Tuesday.

With Messi multi-tasking, however, anything is possible for this tired team.
Real Madrid suffered a double blow with the Croatian and Gareth Bale both picking up injuries on Saturday, while Bayern's injury crisis continues

Real Madrid were the latest team to be struck with an injury crisis heading into the second legs of the Champions League quarter-finals.
Luka Modric looks set to be out for the remainder of the campaign after picking up a knee injury in Saturday’s win over Malaga, while Gareth Bale will miss Wednesday’s meeting with Atletico Madrid having suffered a calf strain on Saturday.
The absence of the former Tottenham duo adds to that of Marcelo, who is serving a suspension, whileSami Khedira could miss the game and there remains a doubt over Karim Benzema, with the Frenchman likely to be given until the last minute to prove his fitness.
Atletico, on the other hand, have no such fears over their side, with Mario Suarez the only omission due to suspension.
Bayern Munich are the other team suffering severely due to injuries in recent weeks. The Bavarian side must fight back from a 3-1 defeat in the first leg without the likes of Arjen RobbenMehdi BenatiaDavid AlabaJavi Martinez and Tom Starke. Initial hopes that Franck Ribery could return to feature in the second leg have all but been wiped out, while Philipp Lahm, who missed Saturday’s win over Hoffenheim, and Bastian Schweinsteiger face a race against time to be fit.
Porto are already without the suspended Danilo and Alex Sandro, while Cristian Tello is not expected to be fit for the game.

Paris Saint-Germain were lucky to see David Luiz make a quick recovery from a hamstring injury in time for their first-leg clash with Barcelona last week as he was called upon to replace the injured Thiago Silva in the first half. The latter has been ruled out of the Camp Nou return after failing to recover from a thigh injury. Thiago Motta has been excluded from the squad as he is also struggling with a thigh injury. Serge Aurier is suspended.
Andres Iniesta was Luis Enrique's only concern but the midfielder has been passed fit. Thomas Vermaelenis the only other likely absentee.
Massimiliano Allegri has admitted the chance of Paul Pogba featuring for Juventus against Monaco on Wednesday is “virtually zero”. The French midfielder remains on the sidelines with Martin Caceres andKwadwo Asamoah.
Monaco, on the other hand, are without Lacina Traore and Tiemoue Bakayoko for the meeting in France.Geoffrey Kondogbia missed the weekend’s meeting with Rennes due to a sprained ankle and Jeremy Toulalan, suffering from a thigh injury, was also absent but both are expected to take on Juve at the Stade Louis II.
The Swede only spent one season in Catalunya before returning to Italy, while the Uruguyan has established himself as a star man for the Blaugrana
Luis Enrique: Ibrahimovic's failure and Suarez's success at Barca baffles me
Barcelona boss Luis Enrique is baffled as to why Luis Suarez has succeeded where Zlatan Ibrahimovic failed by flourishing at Camp Nou.
Ibrahimovic arrived in Catalunya from Inter in 2009 for a reported €70 million but, despite a bright start to his Blaugrana career, the outspoken Swede returned to Italy after a solitary season in which he had a bitter falling-out with then coach Pep Guardiola.
Suarez, meanwhile, initially struggled to prove himself worthy of the €94m transfer fee Barca had paid Liverpool for his services, but his form has improved steadily since the turn of the year and is now back playing at his very best.
With Ibra set to face his former club on Tuesday as Paris Saint-Germain take on Barca in the quarter-finals of the Champions League, Luis Enrique was asked to compare the two striker's contrasting fortunes at Barca.
"I don't know why Suarez has fitted in at Barcelona better than Ibrahimovic," the coach stated. "His goals took a while to arrive but I can only praise his performance and his work ethic. 
"Although you sign a top player, you never know how he will adapt to the team or the city. Those handicaps can go against you but in the case of Suarez he has adapted very quickly. Some players take a while to adapt and others do it fast."
Ibrahimovic was forced to sit out last week's first leg through suspension and the prolific striker was missed, with Laurent Blanc's men slumping to a 3-1 home defeat.
The 33-year-old is now set to make his return to the starting line-up for the return tie, but Luis Enrique insists that the forward's inclusion will not alter his tactical plan.
"Ibrahimovic is back in the team but that doesn’t change matters because PSG will play with the same style," he stated. "We sometimes change it to create more problems for the opponent but not because of individual players.
"The opponent suffered a bad result in the first leg, and they will be looking to win by using every weapon they have. Our objective is clear: we want to win this match.
"I can’t say who stands a better chance of progressing. We need to play another great match to get through, that’s the truth.
"I would say we are at our highest level at the moment but tomorrow we will have to be in top form to face PSG."

PSG midfielder Marco Verratti also missed the first leg through suspension and Luis Enrique expects the Italian to have a big impact on the game, admitting that the 22-year-old is good enough for a place in Barca's much-vaunted midfield.
"Verratti has always been good enough to play for any team," the former Spain international added. "I love the player, ever since I saw him for the first time."
Barca are the favourites to win this season's Champions League in many pundits' eyes, particularly with Lionel Messi in such sensational form.
However, Luis Enrique was keen to play down his side's prospects, while at the same time praising his Argentine No.10 for reaching 400 goals for Barca in Saturday's 2-0 win over Valencia.
"Messi is at his best at the moment," he added. "He is very fit and has scored his 400 goals, which is an impossible figure really - he is unique," he continued.
"But we are not favourites to win the Champions League. We are a candidate for the semi-finals -  so are PSG and every other participant. 
If you cared deeply about something, would you protest? Make a sign? Join a demonstration? How long could you keep going for, in the face of indifference and inaction?
When more than 200 Nigerian girls were kidnapped from their school a year ago by Boko Haram militants, millions of people around the world joined a social media campaign to plead for their safe return.
Charles Alasholuyi was one of those people -- from celebrities to world leaders -- voicing their anger via #BringBackOurGirls, one of the top Twitter hashtags of 2014, used in more than four million tweets.
But as weeks turned into months, there was still no sign of the missing girls. The spotlight on the campaign faded. People stopped tweeting. They stopped marching. They stopped pleading with the Nigerian government to do more to rescue the young students.
It seemed everyone had given up hope that the girls would come back. Many questioned whether they were even still alive. Everyone, that is, except Alasholuyi.The marketing professional and father-of-three has taken time nearly every single day since the girls went missing to hold up a sign featuring the #BringBackOurGirls hashtag, have his colleague take his photo with it, and post it on CNN iReport.
Alasholuyi, a believer in the saying that "an injury done to one, is an injury done to all," says he does this to help give the families of the girls a voice.
He admits his daily routine can be stressful and frustrating and he hopes that one day soon, he will be able to stop doing it.
But so far he hasn't dared give up his commitment, saying he feels a moral obligation to continue posting his daily photo until the girls are returned. He says he doesn't want anyone to forget about them and the struggles their families are facing every day the girls are missing.
Alasholuyi adds messages on the signs like "over 200 stolen dreams," "save the girls now" and "our government has a responsibility to protect us all."Over the past year, he has also worked with organizations who are holding the Nigerian government accountable, demanding they do more to find the girls. Most recently, he participated in a 10-kilometer march through Lagos. He has also met local leaders to highlight the need for girls to be able to get an education without the fear of being abducted.
Alasholuyi has also appealed to his government -- and other nations -- to fight the violence imposed by Boko Haram which has carried out multiple attacks and abductions since the kidnapping of the Chibok girls.
"Yesterday was Chibok, the day before yesterday it was somewhere in the north, today it could be another town. Tomorrow it could be my village," he said. "Why not cry out loud now for the whole world to come to our aid and make sure that the Boko Haram insurgency and their senseless abductions are nipped in the bud."
He told CNN he believes the newly-elected government, which is due to take office on May 29, will step up efforts to locate the girls. He is confident president elect Muhammadu Buhari, the country's newly-elected president and a retired Major General in the Nigerian Army, will do more to combat the threat of Boko Haram.
Alasholuyi says he believes in miracles and hopes his passion, commitment and determination to help the Chibok girls through his daily photos will one day bring them home safely.
#BringBackOurGirls one year on: 'We should all feel shame'
How the world has changed since the kidnappings

After a weekend shipwreck off the coast of Italy that may have killed hundreds of migrants, the International Organization for Migrants said Monday that there may be three more migrant boats in distress in international waters, according to a post on the group's official Twitter account.
Authorities still don't know the fate of many of the passengers, including children, who were on the large ship bound from Libya to Europe that capsized Saturday night in the frigid waters of the Mediterranean Sea. That sinking may be the worst in a series of disasters in which migrants have lost their lives on vessels that are too rickety to survive long voyages.
"Gangs of criminals are putting people on a boat, sometimes even at gunpoint," Maltese Prime Minister Joseph Muscat said. "They're putting them on the road to death, really, and nothing else."
A rescue operation is still underway for people who were on the ship from Libya, and the number of potential victims is not clear. A Bangladeshi survivor told investigators there were 950 people on board. Previous estimates put the number around 700.
Maltese authorities, who are working with Italian rescuers, said around 50 people had been saved. But the Italian Coast Guard said 28 people had been rescued and 24 bodies recovered.
    Migrants have been attempting the perilous journey across the Mediterranean to southern Europe for years, but authorities have reported a sudden surge in the past 10 days, along with a grim spike in the number of those who are killed en route.
    Already this year, more than 900 migrants are believed to have died while crossing the Mediterranean, far more than during the same period in 2014, the International Organization for Migration said last week.
    On Monday, yet another boat sank off the Greek island of Rhodes, killing at least three people, the Greek Merchant Marine Ministry said. Of the 83 people reported on board, at least 57 survived. Those confirmed dead were a man, a woman and a child.

    The latest disaster: 'Nothing less than a genocide'

    The capsizing of the ship that departed from Libya marked the worst such disaster so far.
    As rescuers approached the boat in response to a distress call Saturday night, authorities say, migrants moved to one side, hoping to be saved. Their movement caused the large, multilevel boat to capsize about 110 kilometers (70 miles) north of Libya, sending many passengers plunging into the sea.ccording to one Bangladeshi survivor, large numbers of people remained trapped inside the boat as it sank. Smugglers -- human traffickers organizing the voyages -- had locked the doors to the lower levels of the vessel, the survivor told Italian authorities.
    "Our troops, together with the Italian navy, are literally looking through the bodies to try to find someone who's still alive," Muscat said.
    While the shipwreck was an accident, Muscat slammed the human traffickers whom he accused of risking people's lives by putting them on rickety ships in unpredictable waters.
    It's "genocide -- nothing less than genocide, really," Muscat told CNN.

    The wider picture: 'A mass grave ... in the Mediterranean'

    "A mass grave is being created in the Mediterranean Sea and European policies are responsible," said Loris De Filippi, the president of the international aid group Doctors Without Borders. He compared the high number of deaths to "figures from a war zone."
    De Filippi called on European states to immediately launch large-scale search and rescue operations with proactive patrolling as close as possible to Libyan shores. "Faced with thousands of desperate people fleeing wars and crises, Europe has closed borders, forcing people in search of protection to risk their lives and die at sea," he said. "This tragedy is only just beginning, but it can and should be stopped."

    Cause of the crisis: 'Get to Europe at all costs'

    Many of the migrants who board ships to cross the Mediterranean come from sub-Saharan Africa, often traveling for weeks or months just to get to the ships. They're seeking a better life, but many are exploited by the ruthless smugglers who organize the voyages.
    "There is a well-oiled machine with the human traffickers, first by land and then by sea, and they feel the need for these desperate people who just want to get to Europe at all costs," said Rome-based journalist Barbie Nadeau.
    The situation on board the boat that sank over the weekend isn't unusual, based on accounts of previous voyages.
    On old fishing boats, "people are crammed into what used to be the frozen live tank compartments in the bottom of the ship," Nadeau said. "Those are the cheaper tickets. People that want to be out on the upper deck, which is the prime space, pay a little more for that service."
    Traffickers are believed to charge anywhere from 6,000 euros to 8,000 euros ($6,450 to $8,600) per person for the dangerous voyage, she said.

    Italy's response: 'Not even enough space in ... cemeteries'

    Italy's proximity to the North African coast puts it on the front line of tackling the continent's migration crisis."We're swamped," Sandro Gozi, the Italian minister for European affairs, told French daily Le Monde. "There's not even enough space in Sicily's cemeteries to bury the dead."
    An Italian search and rescue program, Mare Nostrum, was credited with rescuing more than 160,000 migrants in the space of a year. But it ended in October because of budget constraints and criticism from the European Union that the program itself was encouraging migrants to head across the Mediterranean.
    The European Union's border control agency, Frontex, started its own mission in November, known as Triton, with a budget of less than a third of that of Mare Nostrum. Frontex has no vessels or surveillance equipment of its own, so has to rely on European member states to lend it ships.

    Europe's response: 'A total absence' of policy

    As anti-immigrant parties thrive across the continent, European nations are collectively struggling to cope with the migration crisis on their doorstep.
    "We can't act as if each tragedy is the last while crossing our fingers that another one doesn't happen," Gozi told Le Monde, lamenting "a total absence" of European Union policy on how to deal with refugees arriving in Europe.
    The European Commission, the executive branch of the EU, said Sunday it was consulting member states, European agencies and international organizations to prepare what it called a European Migration Strategy to be adopted in mid-May.
    "These are human lives at stake, and the European Union as a whole has a moral and humanitarian obligation to act," it said.
    But international groups say European governments are failing to do enough.
    Doctors Without Borders will begin its own rescue effort, De Filippi said, because "as a medical, humanitarian organization, we simply cannot wait any longer."

    Root of the crisis: 'The desperation subsists'

    European officials say the roots of the crisis are beyond their control.
    "As long as countries of origin and transit do not take action to prevent these desperate trips, people will continue to put their lives at risk," the European Commission said.
    Many of the boats operated by human traffickers set out for Europe from Libya, which has been engulfed by violence and disorder since the fall of former dictator Moammar Gadhafi in 2011. After he was overthrown, the flow of migrants from Libya intensified dramatically.
    Muscat, the Maltese Prime Minister, called for action against the human traffickers operating out of Libya. Security for Libya's borders is essential to "take out these criminal gangs -- these terrorists," he said.
    Italian Prime Minister Matteo Renzi said the focus needs to be on eradicating human trafficking and that the responsibility lies with the whole world, "not just Italy and Malta."
    But talk of ridding the world of human traffickers doesn't address the immediate issue of the vast numbers of migrants willing to risk their lives in the hope of a brighter future in Europe.
    "The people are going to continue to arrive," said Roberta Metsola, a Maltese member of the European Parliament. "The desperation subsists -- there are almost a million people waiting to board boats and come to Europe to seek a better life. And that fact has to be recognized."
    Shops looted and set ablaze. Terrified foreigners hiding in police stations and stadiums. Machete-wielding attackers hacking immigrants to death in major cities in South Africa.
    As attacks against foreigners and their businesses rage on, killing at least six people this week, other nations in the continent are scrambling to evacuate their citizens from South Africa. But this is not the first time xenophobic violence has exploded in a country that tries to portray itself as a diverse "rainbow" nation.

    What triggered this week's attacks?

    They started after Zulu King Goodwill Zwelithini said at a recent gathering that foreigners "should pack their bags and go" because they are taking jobs from citizens, local media reported.
    Shortly after his comments, violence against immigrants erupted in the port city of Durban.
      His office has denied he made the comments, saying journalists misquoted him. While kings are mostly ceremonial figures in the nation, they are influential in their communities.
      But the United Nations said the attacks started in March after a labor dispute between citizens and foreign workers.

      Why are immigrants targeted?

      Some citizens have accused African immigrants of taking their already scarce jobs, undermining businesses owned by locals and contributing to a high crime rate. The nation's unemployment rate is about 25%, according to government figures.
      But resentment over porous borders, growing crime rates, poverty and corruption are also a major concern, analysts say.
      President Jacob Zuma has said his government is addressing the social and economic concerns. But he said immigrants contribute to the nation's economy and bring skills that are in demand, and should not be stereotyped as criminals.
      "While some foreign nationals have been arrested for various crimes, it is misleading and wrong to label or regard all foreign nationals as being involved in crime in the country," Zuma said.

      How many immigrants are in South Africa?

      The nation has about 2 million documented and undocumented immigrants, which is about 4% of the total population, according to a study by the University of the Witwatersrand.
      Zimbabweans make up the largest group of immigrants.
      Also, South Africa is a top travel destination for wealthy Africans because of its proximity and developed infrastructure.

      Has South Africa had xenophobic attacks before?

      Yes. This is the latest in a series of attacks that date back years.
      In January, looters burned businesses owned by foreigners in another wave of xenophobic attacks. In addition, there were other incidents of violence last year, Human Rights Watch said.
      Seven years ago, Johannesburg was the epicenter of more anti-immigrant tensions that left dozens dead in attacks that later spread to Cape Town. Most of the victims were Zimbabweans who had fled repression and dire economic circumstances. In those attacks, police arrested more than 200 people on various charges, including rape, murder, robbery and theft.
      In 2006, xenophobic violence broke out again for several months in Cape Town.

      What are other African nations doing about it?

      Victims of xenophobic attacks have been from various African nations, including Nigeria, Somalia and Ethiopia.
      African nations have condemned the attacks. Kenya, Malawi and Zimbabwe are just a few of the countries evacuating their citizens from South Africa.
      In Zambia, local radio station QFM said it will not play South African music in solidarity with the victims.
      And in Mozambique, South African energy and chemical giant Sasol sent about 340 South African nationals home. The company said Mozambican employees voiced concern about reported violence against their nationals and protested the presence of South African employees in Mozambique.

      Is inequality a contributing factor?

      Most of the attacks have erupted in poor and marginalized areas.
      Despite the progress the nation has made since its apartheid days, inequality still remains a major concern, according to the Nelson Mandela Foundation.
      "It is up to the present and next generations to take up the cudgels where you (Mandela) have left off. It is up to them, through service to deepen our democracy; entrench and defend our constitution; eradicate poverty; eliminate inequality; fight corruption, and serve always with compassion, respect, integrity and tolerance," the foundation said in a statement.
      "Xenophobia, racism and sexism must be fought with tenacity, wisdom and enlightenment."
      As fears of more attacks grow, South Africans have taken to social media and the streets to protest xenophobia and violence.
