Don't know about that but Barcelona were seriously found out last night. I think we are all now discovering that Barcelona's style of Spanish football cannot be imported to the Champions League. They cannot defend set pieces for their life and without Pique, the average height of the Barca defenders is well under six foot. They didn't have a prayer against Muller and Gomez and struggled badly with the pace of Robben. It's almost as though they need two teams, one for La Liga and one for the Champions league. Top all this off with a jaded Messi and they ended up getting what they deserved, nowt! Let's not take anything away from Bayern, they were up from it from the first whistle and looked a different class to Barca, should be an interesting second leg but I still reckon Bayern will make the final.
Lets forget their recent past success shall we? What you've outlined isn't down to style of play, it's down to composition of squad, look at Spainish national team, two world-class CBs and are the complete package, accept RB. Barca have been weak at CB since Puyol is past it and injured easily, I hope they sign a CB in the mould of Hummels, Kompany, someone to sure it up, Mascarano/Song/Busquets at CB? No. I'd like to see Munisea and Barta do well but neither are world class.
Also, their manager is still suffering from cancer and I think PSG was his first game back (?) after his treatment, so there's that, I personally think it'll be better for him and Barca if he steps down I think, the stress of being a manager will certainly be no good for a cancer patient.
Barca need to change personnel slightly, they're being quite static in the market and not addressing key weak areas, but did sign Alba for LB, hopefully a CB, or 2, a healthy manager and I think they'll be unstoppable.
