He's played a decent amount of games. His only complaint is perhaps not getting a few starts ahead of a slightly injured Xavi. For his age he has played a decent amount. He wants to play almost every week for Barcelona ahead of world class midfielders then he needs to think twice. His temperament is questionable here, and if this is his mindset (remember there is a lot of media speculation and his father may be the main culprit) then he's not fit to run barcelona's midfield in the future.
Compare to iniesta, a true legend. Despite being a fantastic player he patiently waited his turn instead of throwing his toys out of the pram.
