Also what do you think is his best position?
His best position is on the right wing. He is in Juventus since 2002 and 95% of the time he played on the right wing in a 4-4-2 formation.
In Italy he played on the right side of the midfield in a 4-3-1-2 but also he was one of the three attackers in 4-3-3 (played on the right side of the attack, of course).
Occasionally he played as a central midfielder in 4-4-2 or 4-3-1-2 and he even gave some of his best matches there, but I'm talking some 10 matches maximum in 8 years.
In short, he is a winger who used to be one of the finest wingers in the world, known for his great crosses, technique and work rate. But right now he is injury prone, slower and the work rate is not one of his qualities anymore. Quite the contrary, you can even say that he's lazy.
Maybe a new team and atmosphere will force him to work harder, though. If you get only 50% of the Camoranesi from 3-4 years ago, you'll get yourself a terrific signing.
