The PSG team was too busy with the Mbappe problem so they forgot a lot of things and what happened this season was quite bad for the PSG team, I saw several of the PSG team's matches and in my opinion there was no good teamwork in Luis Enrique's squad and even at the end Last week they couldn't win against the team at the bottom of the standings, this was quite embarrassing.
Mbappe is PSG's burden. It is true that he is a player who has extraordinary talent, but the issues he has developed since the start of this season will have an impact on all players. I agree with you, PSG is too busy with the Mbappe problem so their basic goals are forgotten, I'm sure that when Mbappe leaves PSG will play better and more solidly, the coach will find it easier to implement strategies.
It is clear that if PSG does not improve completely then it is very likely that they will not win any titles this season and currently there are several Ligue 1 teams that are starting to get better, making it possible for there to be fierce competition in the race for the title.
Total improvement may take time, friends, it can't take a few weeks for them to immediately become stronger, especially with a new coach, they need a transition. But now PSG has started to change its transfer policy by not being overly ambitious in buying expensive players who are labeled as stars but who have no contribution to the team. Now they are buying players according to the club's needs because building a solid and compact team takes time and adaptation. Enrique just needs time, everything needs a process.
