Kaka has lifted the lid on how he managed to sign for Real Madrid.
"Milan, then, didn't sell anyone," he recalled to MARCA.
"They only sold you if you asked for it publicly, and the first time they did it was for [Andriy] Shevchenko to go to Chelsea.
"For me it was different. For the first time, Milan opened the doors to selling a player, it happened in January 2009 with Manchester City.
"The offer came, Milan opened the doors, but I decided to stay.
"But when Milan opened the doors I told myself that if I were to go, it was only to play for Real Madrid. It was the only place that I would leave Milan for.
"At the end of the season, Florentino called [Milan CEO Adriano] Galliani and asked if he would sell Kaka, as they had opened the doors to City in January.
"Then they called my dad and I told him yes, of course, playing in Madrid was my dream."
In fact, Kaka has revealed how Los Blancos paid him less than what he was on in Italy.
"In the end my desire to go to Madrid was so big that I went there with a big wage, but earning less than in Milan," he continued.
"And, clearly, earning less than I would have earned at Manchester City.
"The financial side was important for me but it was never the basis of my decision."
