Wouldn't give you a hard time for backing the Catalans Royboy, there's enough of the top 4 English clubs ruining domestic football nevermind Europe
I used to watch Barca games regularly and when the current team are in attack they remind me of the strength they had about ten years ago - with Luis Enrique, Kluivert, Rivaldo, Giovanni, etc. However with Puyol playing very poorly of late they're weak at the back. Rafael Marquez isn't the player he used to be, though Pique is promising. They haven't got a Frank De Boer or a Phil Cocu to do the gritty work.
They're not really the best in Europe, but I'd put money on this season's competition saying otherwise.
