Responding to questions about the future of Rossoneri defender Thiago Silva – who has been linked with Barcelona and Paris Saint-Germain – the Italy striker said:
"To lose Thiago is hard, hard. It is impossible to replace him. Without Thiago, it is 50 per cent of our team. It's a crime to lose Thiago.
"At end of the Euros I will see if I remain at Milan or I leave. I don't know."
Cassano also courted controversy with his answer to reports that there were two closeted gay players in the Italy squad at the European Championships.
Apparently in jest, the 29-year-old said: "The coach had warned me that you would ask me this question.
"If I say what I think... I hope there are none. But if there are queers here, that's their business."
He later apologised for his comments, saying:
"I sincerely regret that my statements have sparked controversy and protest from gay rights groups.
"Homophobia is a sentiment that is not mine. I did not want to offend anyone and I cannot question the sexual freedom of other people. I only said that it is a problem that does not concern me and it is not for me to pass judgment on the choices of others, who are all respected."
