Kylian Mbappe is refusing to commit to a 12 month option in his PSG contract.
His deal runs to 2024, with a 12 month clause available, but Mbappe is refusing to trigger it, says L'Equipe.
As such, PSG face the prospect of selling the France international this summer, which could see Real Madrid revive plans for the striker.
The clause runs to July 31 before expiring.
PSG management are calm and confident of Mbappe's commitment, though they now face the dilemma of whether to cash in this summer.
