BERLIN - Barcelona takes a 4-0 advantage to Munich but are wary of Bayern's wounded pride when it faces the Germans tonight in the Champions League quarterfinal return leg game.
"Bayern is capable of scoring four goals, all the more so when they are wounded," Guardiola said at a news conference. "I don't believe the statements about them already having given the tie up for lost. I am sure they will put in a good performance and we have to go there with a lot of ambition to win the match. If we are speculative they will roll over us."
Bayern has said the team has an obligation to restore the club's pride.
Boosted by their 4-0 crushing of Eintracht Frankfurt on Saturday, the Germans are looking to bow out with their heads held high.
"With this win we repaired part of the damage but not all of it. We have a lot to do on Tuesday so that we can say goodbye to the competition in a good way," coach Jürgen Klinsmann said.
Meanwhile, Liverpool needs extra inspiration for the enormity of the task it faces at Chelsea in the Champions League tonight, but it may need only look as far as Bolton Wanderers.
Liverpool needs to score at least three goals at Stamford Bridge to have any chance of overcoming Chelsea in the second leg of its quarterfinal tie after losing 3-1 at home to Guus Hiddink's men last week.
Bolton scored three goals in eight minutes at Chelsea on Saturday although, by the time it managed its first, it was already trailing 4-0.
"I am a bit concerned we let in three, but every match is different," said Chelsea coach Hiddink. "However, let's say it is a lesson learnt."
The Reds will be hoping to avoid a second successive exit from the Champions League. However, they have won there already this season when their 1-0 victory in October ended Chelsea's record 86-match unbeaten home run in the Premier League.
