He said: "I do not know if there will be a chance to sign Kaka if Milan does not make the Champions League. They're known as only a buying club."

Asked about the performance of sports director Pedja Mijatovic this season, Calderon added: "It seems to me to have Mijatovic is a luxury for Madrid. He has demonstrated this with 19 signings, players who nobody knew and who have been excellent.

"They have provided us with two Ligas, something that has not happened for 18 years. He is an extraordinary person. I have a very good relationship with him."
