Robinho began his career with the club and spent time on loan there from Manchester City.
Santos recently had a bid for the player rejected by Milan, but speaking to Radio 650 the forward said: “For Santos I am always available.
“I am good friends with the President, Luis Alvaro, and we talk frequently. It is true that Santos recently asked Milan about signing me, but they refused the offer.
“It is a fact that if in the future there should arrive a new offer, I would be ready to take it into consideration.”
