Sampdoria's injured striker Vincenzo Montella says Antonio Cassano must learn from his faults if he is to fulfil his potential.

Montella said of the on-loan Real Madrid striker: "I believe I understand Antonio and know enough to judge his merits and defects. In my opinion he has many qualities and so must try to make the most of those and work on his defects.

"Cassano is a lad who knows what he is doing and is very intelligent. He must learn from his mistakes."
