Robinho won two league titles with Santos earlier in his career before making the move to Spanish giant Real Madrid in 2005, and Odilio Rodrigues says the club would relish the chance to bring Robinho back should the club and player reach a financial compromise.
"Robinho has a strong connection with the city. Here he is an idol, we all want to see him," Rodrigues told Globoesporte. "There was contact with his lawyer, but the negotiation is difficult. Robinho wants Santos, however, it is difficult for us to meet his financial demands.
"It's a difficult negotiation, but not impossible."
After a three-year spell with Real Madrid, Robinho spent two years at Premier League side Manchester City before eventually signing for Milan in 2010 - where he has scored 32 goals for the San Siro outfit.
