If Mabbpe doesn't want to play in this team they should get him out of the team and take benefits from this player by selling Mbappe with a high price to other teams because none can force a player to stay in PSG.
Even by paying him more money still keeping Mbappe is PSG a wrong move because other players are going to be happy for paying too much attention to one player and this can make the team unbalanced.
Selling Mbappe at too high a price will also not make other teams more interested in bidding for him this summer. But if the price is in a very reasonable category, I think there will definitely be many other teams interested in offering Mbappe in the current transfer market. Moreover, he (Mbappe) is a very good forward line player to break his opponent's defense and even if Mbappe wants to move to another team instead of having to stay at PSG, he also cannot choose a random team if he still wants his career to get better.
Mbappe and PSG drama has been lingering and it may continue this way and by next season we might still see Mbappe in the PSG team. Mbappe is truly no longer interested in staying in PSG and also PSG is no longer comfortable with PSG presence.
What the two parties need is a landing conclusion and resolution but if PSG does not force it, that agreement will be delayed. Mbappe is so much self centred about his career and ambition than anyone's else.
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.
