"It is only normal that every year big clubs like Chelsea and Real Madrid make offers for the best players in the world, like Kaka," said representative Gaetano Paolillo on Sky Italia.
"When Roman Abramovich's proposal emerged, Real immediately contacted us to say that if the player was for sale, they were also interested.
"Has he got a future at Chelsea? It depends on Milan," added the agent.
"If President Silvio Berlusconi wants to keep him at Milan, then it is highly unlikely Kaka will leave. If a player is happy, he stays with his club."
