Lionel Messi says Barcelona will “try” to achieve what seems like an almost impossible comeback when Bayern Munich visit the Nou Camp next week.

The Spanish league leaders were thrashed 4-0 in the first leg of their semi-final by a hugely impressive Bayern Munich side.

Few will give Barca any hope of overturning the result, but after turning around a 2-0 first leg deficit in the previous round against AC Milan, hope remains in Catalonia.

"The comeback is very complicated," Messi said. "Bayern are a very good team, but we'll try.

"We need to get (ourselves) up, win the league and try to overcome this and if we cannot then think of next season."

There were doubts over the fitness of Messi ahead of the match and the World Player of the Year put in a subdued performance by his high standard. Yet the Argentine says he had "felt good".

Messi was honest about Bayern's total eclipsing of the La Liga side, telling reporters: "They were better than us, they were much stronger. They were superior in everything."

Barcelona may also look to Bayern's defeat against Arsenal earlier in the competition when after taking a commanding 3-1 lead in the first leg, they slumped to a 2-0 loss in the second, only progressing on away goals.
