I felt he was his own Cassano when he came to the squad. I liked a few of the goals in his first season, but I always felt the guy was playing for himself more than the team -- a hog with the ball, stupid decisions, ridiculous shots into the parking lot way too often.
By the time his second season for Juventus rolled around, the magnifying glass came out on all his flaws. He started making Cassano look like a good sport with a cool head for making good decisions on the pitch.
When he left, it was "good riddance"... even today. That guy left a bad taste in my mouth. (I think it was "camel".)
