It seems that Mbappe is ready to move to Real Madrid next year as a free agent and if this is true, it is unclear how PSG will behave. Will Mbappe make the squad? On the one hand, to put him in the squad knowing that the player is leaving is not very good, because it is not very clear how he will play? Will he give his all and even if he does, the club still knows that he will leave at the end of the season.
PSG can put young and promising players in Mbappe's place, but then a player who gets a lot of money will just sit on the bench.
In general, Mbappe has created a lot of problems for the club with his decision.
Kane seemed to want to go to Bayern, but so far Tottenham have not given permission for the transition.
If Mbappe stays, of course he will play his best in every possible game (obviously taking into account the need to rest, etc.) - it is too expensive to keep one of the strongest strikers and the most expensive player on the bench. After all, PSG are paying him for his services, so they should try to get the most for their fee. And I don't think that Mbappe created any problems for PSG - he pulled this club all these years, they should be grateful to him.
Yes, as a professional player, even though a player doesn't feel comfortable at the club, he has to give his best, at least until his contract ends. and I'm sure Mbappe can do well and play professionally. One season is not a long time in the competition, especially if there are changes that might make the player reconsider his decision to continue or actually leave after his contract ends.
Paris Saint GErmain should have improved instead of thinking about their star players leaving them one by one, because one of the reasons why they left was the disharmony that made them uncomfortable.
