Marc-Antoine Fortune has urged Celtic to deal in Landry N'Guemo.
His loan deal from French outfit Nancy expires at the end of the season.
Striker Fortune said: "I think Landry has done enough to stay here.
"He's a player who loves the game and he has shown he is one of the main pieces of the team. He works in the middle, takes the ball and goes forward.
"He has shown enough to sign a longer contract. I know he is happy here."
