I think by now it is pretty obvious to anyone, that Mbappe does not want to play for Paris Saint Germain anymore. Therefore i would hope that the official of PSG are already planning for the time after Mbappe. When he is gone i think it is safe to say that the time of the huge names at PSG is over. Only Neymar is left then and it is not even sure yet if he will maybe also leave the club.
I also think that in retrospective the whole PSG strategy so far was a pretty big fail. They have spent ridiculously high amounts of money to buy the biggest names in the sports, no matter if it is good for the chemistry in the team or not. The most recent transfers make more sense in my opinion. Good players without huge names.
PSG is in a state of uncertainty, even though we know that many of its policies conflict with the wishes of the players. Neymar is more silent than boasting about what he feels, even though I'm sure Neymar is no longer comfortable. As for Mbappe, who has said in several interviews he has started to expose PSG's disgrace, even though so far PSG has offered more than other players. Because at this time a new coach like Enrique, PSG style of play must change a little and the pattern of selecting players is at least not the same as when the previous coach was. Maybe it looked good to have star players but the results weren't so promising in the end. Failing to win the UCL trophy many times will be a tough task for Enrique next season.
