The French Football Federation has rejected Paris Saint-Germain's request to reconsider an order from the French league to pay former striker Kylian Mbappe 55 million euros (£46m) in back pay.
The request to the FFF's executive committee was submitted a day late, a source close to the case told AFP on Friday, after the club was given 10 days to appeal the league's ruling on October 25th.
A French league appeals committee has attempted to mediate the increasingly bitter row between Real Madrid forward Mbappe and the club he left this year.
Mbappe has demanded the figure which he says is made up of the final three months of his salary plus several bonuses.
But Qatar-owned PSG argue that the 25-year-old had agreed to waive the sum in August 2023.
