Cassano has joined Samp on-loan from Real Madrid and Mazzone declared: "He has the greatest potential you can see in a player. But he must talk less and concentrate on doing well for Sampdoria. I've already seen him doing too many interviews.
"He's done wrong by (Fabio) Capello and done wrong by the fans. He shouldn't forget the good life that he has. He could be as good as Giuseppe Signori, he has that sort of talent. He must not waste it."
