The Russia boss has had his say on the flamboyant attacker's behavior after he was dropped from the Inter squad for the match versus Catania.
Cassano was dropped from the Inter squad for the 3-2 Serie A win over Catania at the weekend following a quarrel with Stramaccioni in the dressing room after Friday's training session, and Capello believes that the forward's behavior has hindered him throughout his career.
"Cassano is a good lad. He's very generous and has a lot of talent. However, he does not know the limits of respect," Capello told Rai.
"He has a certain vision on football and that's the only right way for him. He loses the respect of his teammates because of this. He should learn that there are times where you have to accept other people's decisions. It's a real shame because he could have achieved a lot more."
Cassano has apologized for Friday's events and is expected to make his comeback against Tottenham in the Europa League on Thursday.
