Yes, of course PSG will not let him go, that's why he put a fantastic price on Mbappe to put pressure on the mentality of the team that wants to recruit him, and I also think that real Madrid will not take the consequences of spending a lot of money on Mbappe if such a position.
yes at least mbappe brings a little hope to PSG's performance in every match, especially in the domestic league to maintain their position.
Yeah actually PSG is really doing everything possible to make sure that Mbappe doesn't leave PSG because the club is still wondering how they can be able to cope without the presence of Mbappe that's why they are willing to do everything possible to make sure that Mbappe stays with PSG, perhaps this issue has made Mbappe realize how important his role is on PSG.
Although I believe he may reconsider staying a bit longer because I don't think there is any club that can treat him the way PSG does, which is one of the factors that improve and enhances performance of a player is when they are being respected and treated well, although I believe that the only way he will like to leave PSG is because of English league.
the situation will be difficult for PSG if Mbappe leaves them. especially if PSG is not ready to replace him in the team. they will negotiate for Mbappe to stay with PSG. but Mbappe wants development and challenges. and the Premier League is a good place for him to develop alongside tougher competition. we have to realize that the French League is not as tight as the English League. maybe Mbappe realized that.
