I think PSG are too selfish and possible because their selfishness means they will lose Mbappe next season without getting anything, even though if PSG want to let Mbappe go this season they can get fresh funds to be able to bring in other players.
Sooner or later, Mbappe will definitely leave PSG and start his career with his new team, and I'm sure Mbappe really wants to join the Real Madrid team because it is possible for Mbappe to achieve everything in his football career with the Real Madrid team.
I think PSG are willing to sell Kylian Mbappe this summer because according to news, the club already issued an ultimatum to Mbappe to decide his future whether he wants to leave this summer or accept a new contract. I see this situation as a huge risk on club’s side, they could end up losing Mbappe for free next season if they are not careful. Real Madrid are already waiting patiently and plotting a quick hijack immediately a decision is made by the player to leave PSG.
