Kaka has committed himself to AC Milan for next season.
The midfielder's contract carries a break clause, but he says he's staying.
"Am I staying at Milan? Yes, yes," he assured. "I want to remain for another year, but then it's up to the club to decide.
"I still enjoy playing football. I had physical problems in Madrid and that moment the pain was stronger than the pleasure.
"In Madrid I learned to have faith, perseverance, patience and much more beyond football. The results weren't what we expected and it was not easy to deal with the pressure, as it was a situation I wasn't accustomed to."
