I mean why would Mbappe want to stay here any longer? PSG are still struggling too much as you have seen until now. They might even be under the danger of dropping to the Europa League after the group stage. Because that performance against Newcastle was horrible and they would experience that also if they continue playing similarly.

Mbappe has of course been given a lot of money by PSG to extend his contract. However I don't think the same thing would be enough to convince him now.

Because for example Real Madrid are also very rich and Mbappe can simply choose them and continue to make a lot of money.
