Since the project now failed in a way it could indeed have consequences in the long run. The players that joined PSG in recent years thought that they will become a part of a project that will dominate the European soccer for many years and frequently win the Champions League with Mbappe, Neymar and Messi, but quite the opposite was the case. When PSG now reaches out to players the only enticement they have in their repertoire now is money. It will all be about the money. There is no Messi anymore and soon there will be no Mbappe. When players now go there it is not because they are playing with the best players in the world, but because they get paid more at PSG than elsewhere.
Football is changing, PSG is not the only club where they can pay more, and you are right now it is clear that the team is going through a stage when players are disillusioned with the club and are trying to find another place where they can realize their goals. Perhaps in the off-season, PSG will once again bring together star players, but they have done it so many times and now it's all over again, it doesn't look like it can bring them the desired result.
