This was a critical time for him and he dropped the ball.
He stopped being a solid presence and started being a liability for Palermo this season. Where he went this summer would have determined his chance for a future:
Go to Fiorentina (or Juventus) and get a solid coach in a solid team playing in top competitions surrounded by great players (Juve moreso obviously), take a little less money to make it work. Probably end up a better player for it.
Go to a mid-table German club, get some UEFA matches, get partnered with another weak-link whose drive and talent died with that own goal and probably stagnate or get worse.
