Lyon have not named Nabil Fekir in their squad for the friendly against Chelsea.
The Daily Mail says Fekir has been left out of the Lyon squad to play against them in a pre-season friendly on Tuesday night as he refuses to rule out a late switch to Stamford Bridge.
France midfielder Fekir has been the subject of heavy speculation all summer linking him with a move away from Ligue 1.
He looked poised to move to Liverpool before the World Cup started but issues in his medical brought that deal to a standstill.
Fekir only returned to pre-season training on Monday following his role in France's World Cup winning campaign.
