Milan will be forced to pay Real Madrid a small fee for Kaka if the Diavolo finish in the top three, claims the Gazzetta dello Sport.
The Brazilian returned to San Siro this summer on a free transfer, four years after heading to Spain for €65m.
“Real Madrid can receive a fee for Kaka depending on the League position which Milan end the campaign in,” noted Real chief Florentino Perez at the weekend’s general assembly.
Perez mentioned no figure, but the Gazzetta claim the Italians will have to hand over €3m if they qualify for the Champions League.
Meanwhile, Kaka has told Sky Sport Italia about his problematic stint in Spain with the European giants.
“I return to Milan as a stronger player and more experienced after four difficult years personally and professionally,” he stated.
“In Madrid I learned to suffer the critics, to be challenged and to be constantly under pressure. So many doubts have made me grow.
“The atmosphere at Real Madrid is like that of many other clubs. In Milan, the relationships are closer.
“I face this new experience with a different consciousness to my previous stage. Now I have to exert a role of leader.
“I hope to be in Milan for a long time, to help those who are younger and still learning. Milan 10 years ago was different, but the feelings are the same. It is as if I had never left.”
Kaka is currently sidelined after he picked up a thigh muscle strain on his debut at Torino.
