Messi pessimistic about overturning Bayern deficit EVEN Lionel Messi, so often Barcelona's saviour, was at a loss to explain how the La Liga leaders can come back from their Champions League semi-final mauling in Munich. Barca were thumped 4-0 away by an impressive Bayern Munich in their first leg on Tuesday night, putting in one of their most toothless displays in recent memory. Yesterday, they were greeted with newspaper headlines such as "Historic beating" in Madrid-based daily Marca, "Catastrophe" in Barcelona-based Mundo Deportivo, and "Azulgrana Waterloo" in daily El Mundo. The Barca players looked dazed and downcast as they spoke to reporters after the match and lacked conviction when asked about their chances of turning the result around at the Nou Camp next Wednesday. They were better than us, they were much stronger. They beat us in everything and were superior," world player of the year Messi said. A comeback is difficult, Bayern are a very good team. We have to lift ourselves, try to secure the league title and try to turn this round. If we can't, we need to start thinking about next season. Barca could be crowned La Liga champions for the fourth time in five years if they can beat Athletic Bilbao on Saturday, and Real Madrid lose the city derby at Atletico. Argentine forward Messi has been the outstanding figure in a Barcelona side that won the European Cup in 2009 and 2011 and his goals helped them to a sixth consecutive Champions League semi-final. But he was a barely noticed presence in Munich. He injured a hamstring against Paris St Germain in the quarter-final first leg and, apart from a brief but decisive substitute appearance to help Barca through the second leg two weeks ago, has not played since. On Monday, he was given the all-clear to feature against Bayern but, on the pitch, looked short of spark and energy as he was crowded out time and again. "I haven't played for a long time but I felt fine," Messi said when asked about his fitness. While Messi faltered, Barca coach Tito Vilanova's lack of faith in his alternatives up front was startling. He did not make a substitution until the 83rd minute, bringing on striker David Villa for Pedro, by which time his side were already 4-0 down. His other two possible changes were not made. Asked if the side was too reliant on Messi, Dani Alves retorted: "The debate on our "Messi-dependency" only appears when we lose. It will be very difficult [to turn around]. But, if we have to fall, let us do it with our heads held high. We haven't said the last word in this. Barca came back from a 2-0 first-leg reverse to defeat AC Milan 4-0 at home in their last-16 tie in March, but the latest defeat felt more decisive.There is a feeling that the side is running out of steam. Their pressing game high up the pitch has dropped off and the circulation of the ball has lost its zip, in stark contrast to a dynamic and imposing Bayern. "They beat us with their physical fitness," Barca captain Xavi told reporters. We have to work a miracle. There are 90 minutes remaining and it is practically impossible, but we have to try because we wear the badge of Barcelona.
