Former Bayern Munich goalkeeper Jean-Marie Pfaff questioned whether Barcelona can reach the UEFA Champions League final if Lionel Messi does not play well.
Barcelona were drawn against Bayern in the Champions League semi-finals on Friday, with the Bavarians' coach Pep Guardiola set to face his former club in a competitive fixture for the first time since moving to Germany.
"Barcelona is a great team but I believe the collective Bayern Munich is much stronger," the Belgian said.
"If at Barcelona Messi doesn't have a good day, half of the team isn't good. The striker can be good but if the last pass doesn't come it's difficult.
"I think the whole team of Bayern Munich, from the goalkeeper to any other player can combine very well."
"Yes, this is a difficult game. And this is of course a very big game," he said.
"To play in Barcelona against Neymar, Messi and Suarez; with these three strikers the defence of Bayern Munich has to stay very concentrated.
"But the game is about two lots of 90 minutes. And so I think that Bayern Munich will go through."
