Robinho has declared his commitment to AC Milan.
Santos are keen to lure him back to Brazil.
"I don't know if Santos are really that interested in me or if they are ready to make a concrete offer," the forward told the Gazzetta dello Sport.
"They were my first team and I have always had a special relationship with them, but you have to think about the present.
"Right now I have a contract with the Rossoneri, I want to respect it and I'm happy here because I feel important at this club."
