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.
PSG are quite cautious about Mbappe changing clubs as they will never let Mbappe leave the club as a free agent member. PSG has directly stated that he will either leave the club this season or extend his contract. Since the club's contract with Mbappe has not yet expired, Mbappe is obliged to accept the terms of the club. Since PSG management has given two conditions, Mbappe must choose one of the conditions. If any one of the two conditions is chosen, there is PSG profit both conditions are made for PSG's profit. And it is normal to give such conditions to the player because Mbappe must understand that a world best star like Mbappe will never leave any club as a free agent member. The club has spent so much money on Mbappe that if he doesn't get some cash when he leaves, the money spent will be wasted.
