Kaka says he'll always be a fan of AC Milan.
Kaka has signed with MLS expansion club Orlando City and will spend the first-half of next season on-loan with Sao Paulo.
"It's a difficult moment for me even though I am going back to Brazil and I am starting a new adventure in America," Kaka said in an interview with Milan Channel.
"I will miss hearing the chanting of the Milan fans and my relationship with the club will always remain the same.
"I am and always will be a Milan fan, I hope to soon send messages to Galliani saying that we are champions of Italy and Europe. I am leaving a lot of friends here.
"I am sure that Milan will come again, it will be an important year for them to start again and they can get a lot of satisfaction out of it.
"To have come back was important for me, it was a special season for me on a personal level. The fans have always been close to us."
