Any miracle will depend on Messi

The Argentine showed in Bilbao that he is ready for Bayern

Nobody in Barcelona is talking about epic comebacks, but obviously a miracle, should one occur, depends on Leo Messi. The Argentine proved in San Mamés that he is fully fit and ready. He is back.
During his first public appearance since his return from New York, Vilanova confirmed: "It wouldn’t be very convincing if I came here and said that we’re definitely going to stage a comeback, but we’re Barcelona and we have a duty to our supporters. We’ll just have to see what happens during the game. What we can’t say is that we can’t do it".
Barça believes there is still a chance of reaching the Wembley final, especially after seeing that Messi is fit. 30 seconds after coming on at San Mamés, the Argentine surged forward and shot on goal. After eight minutes he scored an cracker. Messi has already proven on a number of occasions what type of player he is and he was crucial in the comeback against Milan, where he scored two of his side’s goals.
He played 32 minutes in Bilbao, but just 30 seconds after coming on he had already made it very clear that he was back to his old self. On Sunday he did recovery training in San Joan Despí. The objective is to take care of him, not take any risks, for him to feel fit and for him to play. Nothing more, nothing less. "How are we expected not to depend on the best player in the world?", Vilanova asked.
