Sylvinho admits he's unsure if Robinho will return to Manchester City next season.
City have been without record signing Robinho since he returned to Brazil to join Santos on loan in January.
The 26-year-old had cut a frustrated figure in his final months at Eastlands and Sylvinho conceded it is unlikely his countryman will return to Manchester.
He said: "I don't know (if he'll come back). I think his mentality is in Santos now and after that he's going to be at the World Cup and I wish luck to him and the national team. The future is really difficult to say."
