Totti said worse, He's openly stated that if he had gone to Madrid he would have won Ballon d'ors.
Sure, some people are humble. Some are confident. If the end result is that they can back up their claims then that's fine by me.
You say we don't need to blow this out of proportion, well then the best thing to do would be absolutely nothing.
If we ask Vidal to retract his statement. What kind of message does that send to him? That we don't think he's as good as he does, or that we're a club with a provincial underdog attitude
Meanwhile, managers of other star players constantly big them up in the media. It sure as hell hasn't stopped Messi, Ronaldo, Ibra & pretty much every Bayern player from carrying on as they do. There is no one correct way of doing thing. And personally i'll be pissed if we try to destroy the confidence of our best player. Because of some sort of weird inferiority complex at the club.
