Please, we can agree or disagree on things, but painting things for how they werent is bit much some of these things. Messi's foul on Arbeloa (jumped up for heading duel, very late, and pushed him away) is NOT the same as Adebayor completely mauling down WWE style on Busquets. Its details like that gets skewed/twisted in the bigger picture. A minor thing like that becomes part of some big overlapping conspiracy, its bit ridicolous, when one saw these sitautions in own eyes recently, and not some fuzzy event long time ago.
And if you want to mention stuff like that, do it for both sides, Marcelo&Ramos were lucky to not been sent off in first leg, especially Marcelo's stomp. And Carvalho realized the ref was simply too afraid to make the deicisons needed in the 2nd leg, and fouled viciously enough to get 2 red cards, let alone one. I know for some reason diving gets way more attention then cynical wreckless fouling, but doesnt mean its forgotten.
