#2 Antonio Cassano
Cassano was considered as the 'future' of Italian football, but due to multiple injuries and disciplinary issues, he was forced to change clubs on a regular basis, and was neglected by world-class managers later in his career.
However, that does not change the fact that he was an extremely talented football player with an eye for goal, and possessed the leadership quality of a true striker. Cassano's expertise as a goalscorer has been an important factor in his career.
It isn't surprising that he was a part of the Real Madrid squad from 2006 to 2008, and made over 20 appearances for Los Blancos. But with the growing number of options on the bench, and a relatively low goal scoring ratio, Cassano departed the Santiago Bernabeu, and joined Sampdoria in 2008.
Fabio Capello, former Real Madrid manager described this move as a 'waste of talent', as Cassano's skills could have been better used at the Bernabeu.
