We know he won't behave, so he won't fit in Juve. It's his personality, he isn't behaving while he's getting the backing of Inter and Manchester City fans, imagine what he would do the first couple of months when get abused by the retarded fans. Self-destruction.
I wonder why any team would like to sign Balotelli. He's talented but he's not alone in that. Don't even think his talent outweighs his misbehaving on the pitch.
