Asked about the England manager, who has praised Cassano for his form this season, the striker said: "If he said good things about me, it's because I'm doing well. I have never said anything serious against him, only what I think.
"I'd be happy not to see him.
"If there was an England v Italy game, I'd be sick."
Cassano, who wants to sign for Samp permanently, added: "I love the people of Sampdoria so much. I'd be happy to cut my salary by 15-20 per cent."
