The former Real Madrid man has been linked with a move away from Eastlands for some time now and he has even stated himself that he wants to leave but Mancini insists he wants to keep him at the club.
"Hopefully in the end Robinho will stay here. In the next day the situation can change but at the moment he stays here and I am very happy for him," Mancini said after City's 4-2 FA Cup fourth round win over Scunthorpe.
"I hope he will stay here but it is important he will stay here happy and enjoy it. He is a very good player. I think he is enjoying Manchester.
"I think one player can stay in a squad only if he is happy - if he wants to play every game and if he wants to work every day. That is most important because the players and manager must be happy."
