PSG team is only able to perform best in League One. But the PSG team is not able to do anything in other leagues. PSG have enough players in their squad who can do great things. But due to some mistakes of the coach of the team, the team is currently failing to do well in other leagues.
I don't really understand whether every club's failure in prestigious competitions is the coach's fault. Then what about a club like Paris Saint Germain who have never win the Champions League, for example, even after change coach?
Excess star players is also not always good for a team, it will actually create new problems with the team
