The 28-year-old Brazilian appears poised to leave the San Siro and is reportedly hoping for a move back to his homeland.
Flamengo have had a €6m bid for the ex-Real Madrid and Manchester City player turned down, while Fluminense and Sao Paulo are both rumoured to be interested.
However, it appears Robinho's own preference would be a return to Santos - the team with which he began his career.
"Everyone knows how much I like Santos," he told Globo Esporte. "I grew up there, I have a beautiful history at the club.
"Flamengo are a great club, too. Both clubs are big, but there is nothing decided yet. I am still under contract with Milan. Let's see."
Robinho previously returned to Santos for a six-month loan spell from Manchester City in January 2010 and although he expressed a desire to stay, City refused to renew his loan and the two clubs were unable to agree a transfer fee.
The Brazilian subsequently moved to Milan, where he has been reduced a bit-part role this season, starting only seven games for Massimiliano Allegri's side.
Despite that frustration, Robinho insists he will respect his contract at the San Siro.
He added: "Everything is fine regarding the club. If I leave or not, I don't know. Only God knows the future.
"What is certain is that I have a contract and I am a Milan player."
Sao Paulo are understood to be keen on signing Robinho as a replacement for Paris Saint-Germain-bound Lucas Moura.
