Bench tactician Pep Guardiola said he should take the blame for Bayern Munich's collapse in the second leg of their UEFA Champions League clash with Real Madrid last Tuesday, adding punishment should be appropriate for his failure to bring the German powerhouse back to the finals.

"We played badly, that's my responsibility," Guardiola told reporters. "We are at the highest level in Europe and such errors are punished. I'll try to lift the players. It is a fresh experience now, but it is too early for a general analysis.

"If you don't play well and you defend set pieces badly, that's just how it is. We are playing at the highest level in Europe, and such mistakes are punished right away. Bayern are a big side. I will try to lift the players again.

"The reason for the defeat is that we played too little with the ball. If you do not have control of the game, you have no chance against this team.

"When you are playing bad, you concede a lot. We came out very energised, it was a back-and-forth game, we could have scored with our chances, but we didn't. Us playing bad is the only one explanation for this defeat.
