The Brazilian had two spells with the Rossoneri.
“Some love affairs never end," Kaka told FIFA TV. “Could I go back to the Rossoneri one day? I don't know, for now I'm happy in the US. I loved playing for Milan, and I think there will always be an open door for me."
However, Kaka appeared to rule out returning as Diavolo Coach.
“I don't think I'll be a Coach, for now I don't like it. Maybe over the next three years, when I stop, I'll think about it."
