10 other players lost against Inter with him, his two collegues in the top 3 for this award included. He was still one of the best players in CL (best for Barca) despite losing to a better team in Inter.
Argies were a joke as a team in WC, Messi was one of the best players in the group stage despite the fail, but despite just being half a year ago, I'm guessing its already forgotten because he didnt score.
He has had one THE most ridicolous season I ever seen a player have, only comparable to Ronaldo's one of 96-97. It would be funny if he wouldnt win it because of a WC where there not much of standout players (usually great spain NT were rather boring, Xavi the midfield maestro, but only player that really stood out for me in WC was forlan). And lose it to a teammate who he is undoubtly superior to, despite that teammate being the best midfielder in the world.
