Barca looked defensively vulnerable against the lower oppositions recently but whenever they face Madrid they play as if it is their last day on earth. I might sound outrageous but I think Mou should bench CR7 and then bring him as a sub. Play Benz up front with Ozil, kaka, Callejon backing him up. Xabi and Lass in mid. Coentrao and Marcelo as fullbacks. Sergio and Pepe( if he's playing) as CB.saint iker GK. We've already lost freakin 5 times to Barca before so Mou should experiment this game.

HALA Madrid!!
