AC Milan star Kaka says he could be forced to quit Italian football if the violence continues.

There have been several instances of hooliganism in recent times, and the problems reached a peak at the weekend after Kaka, who has been repeatedly linked with a move to Real Madrid, has already spoken of his concerns that the violence could deter top players from moving to Serie A, and has now suggested it could lead him to leave Milan to protect his family.

"Could I leave Italy? Yes, if the episodes of violence continue," he told Gazzetta dello Sport.

"The football I love is happiness. At this time, I can't enjoy myself. Should there be big problems that would prevent me doing my job in an adequate way, anything could happen.

"There is the possibility of going to another country.

"I'm also worried for my family's safety. My wife and parents frequently come to the stadium. How can you be tranquil in this way?"
