Agree with Capi. The media needs a "bad boy" and Balotelli is it.
He has a certain arrogance, but that's only cos he fully believes in his own abilities, and always has. And he can actually back his attitude with his ability. Nothing wrong with that. Not everyone can have a bland, humble personality like say a Giggs or Ramsey
If Wenger could sign and manage the likes of Bendtner and young RVP, then Balo isn't a problem.
