The Real Madrid star said:" At one point it was better for both AC Milan and I to leave. Milan opened the doors for me and it was a sign. My motives were no longer the same as those of the team. And if one day I had to leave Milan, I had always liked the idea of playing in Madrid.
"I could've gone with Ancelotti to Chelsea but I told him to come to Madrid was my dream."
Asked about this season's Champions League favourites, Kaka added: "Chelsea have everything. They're playing very well."
