Milan general manager Adriano Galliani insists Kaka will not leave the club in the summer after the Brazilian turned down a move to Manchester City.
Kaka turned down an approach from City at the start of the week and has subsequently been linked with an end-of-season move to Real Madrid.
Reports claim that former Real president Florentino Perez will try to sign Kaka, if he returns to the Bernabeu as Ramon Calderon’s successor.
However, Galliani is confident Kaka will be at the San Siro in the long term.
“Kaka forever,” said Galliani to the Italian press. “He will not move, he will remain here for the next four-and-a-half years or for longer.
“If Perez was to ask me about Kaka I would say no to him as well.
“I don’t want to talk anymore about Kaka’s situation. All’s well that ends well.
“After this situation, I reiterate that Kaka will not move.”
Chelsea have also been linked with a bid for the playmaker, with Kaka claiming he is flattered to be linked with a move to other clubs.
“It doesn’t upset me to hear that great clubs like Chelsea and Real Madrid are interested in me,” Kaka told AS.
“However, I haven’t wanted to comment over the last few days because I felt a lot of pressure on me and the situation with Manchester City was too fresh.
“I’d prefer to stay calm because one day the press send me to Real Madrid and the next it’s Chelsea. I will talk properly when everything has calmed down.”
