I'm sorrs, but that's pretty much the least knowledgeable claim you can come up with. Watch Tifo's video on how Messi would fit in at City and you know what I mean. This whole 'Messi can only excel in Barca's system" can only be labelled as nonsense. There isn't even a Barca system since the coaches during Messi's time there had vastly different approaches. And Messi himself excelled as a 9, 10, second striker and inverted winger. Tifo says something like "from a tactical perspective, where Messi played was mote dependent on the weaknesses of the players surrounding him than his own, at times being shifted from position to position based on the team mates the coach picked".
