AC Milan ace Kaka opens door to Real Madrid

AC Milan ace Kaka won't rule out a future move to Real Madrid.

Real president Ramon Calderon is thought to be lining up a fresh bid for Kaka in the January transfer window as the La Liga champions bid to defend their title.

Milan club president Silvio Berlusconi, however, has said that the Serie A giants would do their best to prevent their star asset from leaving.

Kaka, though, has not ruled out a move to Italy in the wake of the fresh speculation.

"I have a contract with Milan until 2011, I am not in a hurry to renew it and neither are Milan," Kaka told Italian media.

"Calderon must talk with Berlusconi. If they find an agreement OK, otherwise I stay here."
