The team is responsible for the mistakes," Mueller said.

For month several pundits have been talking about Bayern's squad having lost their balance. "The team lacks speed in their forwarding game and is still looking for consistency. And the real challenges are still to come. The team has to improve a lot," Thomas Strunz commented.
