In fact, when Mbappe last season was not in the PSG squad on several occasions, PSG more often got bad results when Mbappe was absent. Therefore, it will certainly still be a difficult season for PSG to get good results next season, because at least PSG will also still adapt after Mbappe departure. Indeed, I also admit that PSG will still be able and easy to bring in their target players in the transfer market later. But still, for me personally quite sure, even though PSG still has a good squad and manager, but to be consistent and to dominate Ligue 1 without Mbappe it will still be difficult. Therefore, this factor will open up a good chance for other teams to be able to enter the team in the title candidate next season.
This is a result of their dependence on Mbappe, so that Mbappe's absence is felt when they play. But let's see whether they will be able to get rid of that dependency quickly or not, but what is clear is that I won't rush to say that it will be difficult for them after Mbappe's departure, I will first see how they perform next season.
But I hope they will be able to play as usual and even better next season. For Ligue 1, maybe I won't discuss it further, but what I want to see is how they perform in the Champions League after being without "star" players. Will that make it more difficult for them or will it actually give them a new color because they can play more relying on team cohesion.
