He's just a bit cocky, wishing for his leg to be broken is a bit too much. I don't understand why everybody is so angry, he think he's the best in the world, good for him.
I know he's not the best in the world but if he wants to believe that then that's up to him.Not the best in the world, and with his attitude may never be.
I did like the way in that video as Totti was walking off, an Inter guy shook his hand briefly. Even his own teammates hate him.
