I remember in the game played against Espanyol I think , Messi wanted to give a penalty to Masche but he refused. I think it's in the game where Messi hugged Pep.
Monster of a DM (not gonna bench Busquets or anything, but still), but imo he just isn't a CB. One of his best games (and imo his most important) in a Barca shirt (Arsenal at Camp Nou) was at DM.
He simply shouldn't be played at CB. No excuses can justify it, have they not learnt anything in the past 2 years? Bartra would've easily sufficed vs Elche. I'm also pretty confident he fouled the guy on purpose and tried to make it look accidental, he's sneaky that way and has done it before.
