Making his first start of the season, he lasted just 39 minutes before limping off with a new thigh injury. He did not wait for the bench to complete the substitution, instead walking straight off the pitch.
Teammate Vincenzo Montella tried to stop him, but Cassano shook off his hand and clearly swore at the former Roma man, demanding to be left alone and asking him "are you crazy?"
Samp coach Walter Mazzarri said: "Antonio Cassano was just angry at sustaining another injury in his first start of the season, that is all. Nothing seems to be going his way. There are no other problems, I can guarantee that."
