Robinho's wage demands could scupper Santos' efforts to sign the forward from AC Milan this summer, the club's vice-president has admitted.
The attacker's future at the Italian giants hangs in the balance, with several clubs, including MLS outfit Orlando City and South American clubs Cruzeiro and Atletico Mineiro, all keen on a deal for the 30-year-old.
Robinho won two league titles with Santos earlier in his career before making the move to Spanish giants Real Madrid in 2005, and Odilio Rodrigues says the club would relish the chance to bring Robinho back should they 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.
