PSG must be realistic. If they persist in keeping Mbappe in their hands, I think they will lose a lot of money. It's good that they let Mbappe go now, at least they will get some income from the sale. If PSG set a reasonable price for Mbappe, I think there will be several clubs interested in him.
It is reported that there are several clubs that are ready to buy Mbappe at high prices, Liverpool, one of which is said to have prepared funds of 200 million Euros, and there is also Real Madrid, which if they want to buy Mbappe, must sell at least two of their players to get fresh funds, and another Premier League club that is reportedly interested in Mbappe is Arsenal, although Arteta has not officially disclosed it, and it is possible for PSG to work with a wealthy Saudi Arabian club to push the price of this player higher because PSG seems very eager to profit from the sale of this player.
Al Nassr is reportedly ready to buy him but I doubt that Mbappe will be willing to go there because of course the league in Europe is his main choice to make his career continue to shine, if there will be an agreement between PSG and the club that is willing to buy him it looks like this will be a new record high transfer price and hopefully it will pay off with Mbappe's brilliant performances because maybe club that bought him will go bankrupt if it turns out that he is not playing as expected because the club not only has to pay a transfer fee but also a huge salary for him.
