AC Milan president Silvio Berlusconi, under pressure from fans after selling two top players, has not ruled out bringing Real Madrid's Brazilian playmaker Kaka back to the Italian Serie A club after three largely disappointing seasons in Spain.

"Kaka has remained in our hearts because of the player and the man that he is," Berlusconi was quoted as saying on Milan's website on Tuesday.

"I don't rule out a hypothesis of that sort, but it depends on the situation," the former Italian prime minister said.
