There are still many possibilities, but I agree if PSG have to lower transfer fee that man because the price now is not very possible for Real Madrid to sign him. Although Real Madrid has a lot of money, but the previous Bellingham transfer fee may have burden their finances. Actually, if another club brave to recruit Mbappe at current prices then PSG will be ready to let him go, if that happens Real Madrid will wait again to sign that man.
After all, Real Madrid wouldn't make a hasty decision if the transfer fee wasn't so reasonable for them for a player. And while waiting for the transfer fee to be lowered for Mbappe, Real Madrid can also monitor other players to get them if they really can't get Mbappe in the current transfer market. And which teams are starting to be interested in Mbappe apart from Real Madrid? Because a good player like Mbappe will usually be in greater demand by many teams if the price is not too high.
As it stands, Kylian Mbappe is at the top of Real Madrid's transfer target of the summer transfer window and that's why Paris Saint Germaine management has raised the transfer price of the player.
PSG's main reason of trying to frustrate Mbappe's transfer to Real Madrid is because of the fact that he went and had a secret deal with the Spanish club do in other to retaliate that action, PSG has decided to make any deal that'll let the Frenchman join Madrid a difficult one for the both parties
