Real Madrid could find themselves at a disadvantage for Kylian Mbappe as Paris Saint-Germain look to do everything they can to put pressure on the Frenchman and Los Blancos.
With Mbappe refusing to sign a new deal but also rejecting any approach to leave on a transfer this summer, PSG are confident he has already agreed a deal with Real Madrid to join them on a free. next summer.
While it may generally feel like all is fair in love and war at the transfer window, FIFA stops talking to players and actually agreeing deals more than six months before his contract expires.
According to Marca newspaper, PSG are considering submitting an official complaint to the home of world sport, FIFA.
Whether they have reason to do so, or whether the intention is to put pressure on Mbappe and Los Blancos to come to the negotiating table, remains to be seen.
FIFA has in the past banned transfers for incompetent behavior and this may also affect the Mbappe-Real Madrid axis.
