Very few teams will be able to afford him, and even fewer can afford that type of fee. PSG really screwed themselves and they have absolutely no leverage in this situation.
Mbappe is going to RM for free, and PSG can throw whatever fit they want but the facts will always remain the same. They turned down 200m, they gave him a 2 yr contract, and now they are acting like brats now that he wants to leave.
PSG won't learn from this, will throw around even more money, then will be surprised when their mercenaries show no loyalty, again.
