Bayern Munich coach Jurgen Klinsmann has warned his side not to repeat their weekend performance against Wolfsburg in the Champions League clash with Barcelona.
Bayern were routed 5-1 by their Bundesliga rivals, leaving Klinsmann to issue a dire warning to his under-performing side ahead of their trip to the Camp Nou.
He told the club's official website: "It was deja vu, we again lacked an element of resolve.
"The clear message was for everyone to go home and take a good look at himself. Every player needs to look in the mirror and ask whether he gave his all for Bayern Munich.
"The alarm bells are ringing. I urgently need everyone to grasp what's at stake here - the whole of the year 2009 for Bayern and the future of the club.
"It's purely a question of desire. I see this desire in every Champions League match and also in plenty of Bundesliga games, but not all of them.
"The players need to be aware there'll be consequences at some point. At the end of the season, we'll sit down with every player and ask 'what's he given on behalf of Bayern Munich?'.
"However, I'm not scared of Barcelona. My players know the world will be watching. They'll want to prove themselves and show what they can do."
