AC Milan president Silvio Berlusconi is prepared to see Robinho sold this summer.
The Brazilian is in talks with Santos.
Berlusconi said: "I expressed our satisfaction if he remains at Milan, he has nostalgia for the his city, for his family, for his friends and for Santos which is the team in which he started.
"Only Robinho's departure will see a new player come in. If this happens the possibility of his return to Santos would be the only option that would see us give him up."
