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.
Real Madrid’s certainly interested in Mbappé. But I do not know if they are actually going to spend too much money to get him. Real Madrid is a club that is always very careful while spending money. I believe PSG is not reducing the fee for Mbappé because they understand that a lot of clubs are actually going to try to get him. There are a lot of rich clubs which are actually not going to wait. So probably that is why they are not reducing the price of Mbappé. If they genuinely do not reduce the price of him at all, I don’t think Real Madrid is actually going to buy him. With not reducing his price, there is a certain disadvantage for PSG as well. Imagine if no one actually buys Mbappé. They will have to let him go for free.
