Gourcuff, meanwhile, is keen to aid the development of Lyon’s youngsters if he remains at the Stade de Garland.
"When I was the same age as these players, it wasn't exactly the same situation," Gourcuff told the club's official website. "There were more experienced players around me. But it's good. These youngsters are self-disciplined, focused.
"They need to continue relying on the whole squad. I don't have a particular role with regard to them. I simply wish to transmit them my desire of enjoying yourself and that they feel they can count on me on the pitch. I'm here, available, ready to help them.
"I have a hunger to play, I want to play with the ball as much as possible to get my touch back, and then to re-find that technical understanding with the others without neglecting the physical aspect of things.
"It's important at this time. You have to acquire a good technical and physical basis without wearing yourself out."
