Kaka is being heavily linked with a return to AC Milan.

"What we need to do is help him out," the Spain international said. "We need to help so he knows he's our companion, he's our teammate. He's a very important player and he's playing at his level.

"Maybe what he's going through is not comfortable. For us, he's our category of player. Whatever the boss or the club decide, he's a very important player for us.

"We hold him as a team-mate and a professional and as a positive for all of us. I'm wishing him the best."
