Who do you think would win: Spain (without all the Catalans) or Catalonia? On first thought I'd say Catalonia (because of the Xavi-Fabregas-Busquets midfield), but then again, Catalonia don't have too much excellent attackers, so I'm not sure.
------------VV
Montoya-Puyi-Pique-Alba
-----------Busi
----Xavi----------Cesc
Cuenca---Bojan-----Tello

------------Casillas
Juanfran-Ramos-Albiol-Arbeloa
------------Martinez
-----Benat---------Iniesta
Cazorla------Villa------Pedro
I'd like to think that what Catalonia 'lacks' in attack is more than compensated by Spain's lack of proper defense. And then Catalonia's mid field is better than Spain's, coz as brilliant as the Don is he couldn't possibly put up with the brilliance of Busi and Xavi combined!!
Oh and I think Thiago would be obliged to represent Catalonia in case he received the call up... And Spain don't have a mid field prospect better than him.
