Muntari has asked to leave Inter Milan in the January transfer window and Sunderland are reportedly interested in the midfielder.
“Sulley would give us a big boost,” said Gyan.
“He would be loved by the fans if he was here.
“The fans like players who fight for the team and he is certainly one of them.
“Muntari is a quality player, with features similar to Lee Cattermole. He has a big left-foot and can shoot from distance.
“I’ve known him a long time and I would be very happy if it came from us. I’d love to play in the club with him.”
