Kaká has been talking to Sky Sports Italia ahead of AC Milan’s match against Juventus this weekend and has been discussing his time at Real Madrid.
The 31-year-old moved to Spain in 2009 but endured a difficult period and never replicated the form which made him one of the best players in the world previously.
However he admits he would not change his past as he enjoyed a "special experience" at Madrid.
Football Italia quoted Kaká who said: "After what happened with Manchester City [who had a rejected bid in 2009].
"I saw that the club had opened the door to the possibility of my sale, more or less I knew that I would probably be sold.
"These things happen, and from it came a beautiful time, I had in Madrid a very special experience, whilst it will remain in the history of Milan that I went away and returned four years later."
Looking at the present Kaká praised his new manager Clarence Seedorf and admitted he has great trust in the Dutchman.
The pair were previously team mates at Milan, the Brazilian said of his now manager: "Now it is a good moment, we can see the light. We are on the right track.
"He has his own way and is very particular. He has taken a bit of everything and now has his own style, he is trying to put into practice his own philosophy and his work.
"I am a person who has trust for the relationship that we have."
