The Brazilian thinks that now is the right time for him to leave the Santiago Bernabeu and move to a new club.
Real Madrid midfielder Kaka has told the club that he wants to leave, Sky Sports reports.
The Brazilian moved to Real Madrid in 2009 for a then world transfer record fee but struggled to hold down a regular place in the Madrid line-up because of injury.
He could face plenty of time on bench if he were to stay at Madrid this season because of the amount of play-makers the club has.
With that in mind, Kaka has decided that he needs to move away from the club in order to look for a new challenge and hopes his departure can be amicable.
“I want to leave. I think now is the right moment for me and for the club for me to leave amicably,” said the 31-year-old.
“I have spoken to Ancelotti and with the club, they all know.”
Kaka continued: “Things are difficult for me now in the team, and the club knows what I want.
“It’s my obligation to work and keep training, but my father is already working to see if something comes up. I think it’s the best thing for me and the club.”
Kaka has been linked with a move away from Madrid all summer and could now return to his former club AC Milan, who have expressed an interest in re-signing the Brazilian.
Premier League Champions Manchester United could also be interested in signing Kaka as manager David Moyes is desperately looking to sign a quality play-maker before the transfer window closes.
