Capello raps Inter Milan revel Cassano for wasting his talent
Cassano is on the outer at Inter after a bust-up with coach Andrea Stramaccioni.
"It's a shame," Capello commented. "He could have done a lot more in his career than he has. I hoped that he would mature after the birth of his son, but, unfortunately, it is the same old story.
"He's a good kid, generous, but he doesn't understand that there are limits and when he lets loose there is no stopping him.
"He doesn't know the boundaries when it comes to respect. This has influenced his career. He only sees football in his own way. That inevitably sees teammates sometimes lose respect for him.
"He needs to understand that, at certain times, he has to accept the decisions of others."
