Ribery will probably want to be the hero/macho-man and attempt to dribble past Kalou/Bosingwa and he has the ability to actually do it. The thing with Bayern and I think imo that this is their biggest flaw, is that they are willing to make risky passes/dribbles just to get the ball forward, making them prone to counter attacks, it was a major issue last season, and has improved a bit this season, but if you noticed, Dortmund had a lot of fun with that, and counter attacks are something that Chelsea specialize in. If I were Jupp, I would be researching on what tactics are best to defend against counter attacks.
