"Every time I played, I felt muscle fatigue because my legs haven't had enough training. But slowly I started specific training and things are improving."
Cassano's happiness in the Blucerchiati shirt is strongly linked to his relationship with Coach Walter Mazzarri.
"Mazzarri isn't just a great Coach, he is a great person and is capable of leading a big side," Cassano enthused.
"He knows how to manage his players and how to give advice. He lets me play a part in decisions and knows how to treat me and that is the most important thing.
"I always agree with the Coach before the game. He tells me to tell him when I can't play any longer so that I can come off."
