Because in Ligue 1, there is no team as strong as PSG. even without star players with names as big as Messi or Mbappe, they still dominate Ligue 1. if there is a team that threatens, it must be Marseille and Monaco, but with current points difference PSG does not need to worry too much. They just need to be very serious about the Champions League. They have enough difficulty there, facing strong teams that surprised them. They still have the potential to qualify, but hopefully, they can advance to the next round.
I think even the club management is no longer motivated to win Ligue 1 because they are almost certain to get it every season. It even seems like winning Ligue 1 is no longer an achievement that Luis Enrique as the head coach should be proud of. I mean the club management certainly wants to see PSG able to get a good performance in the UCL. Last season they managed to get through to the semifinals and I think that was a very good achievement for PSG. Unfortunately this season with the new UCL format they are in 25th place in the standings. With 3 matches left their only chance is to try to qualify for the playoffs.
For the last few years, PSG has been trying to do well in the Champions League. PSG management has spent a lot of money for this. PSG has added world's best players like Neymar, Mbappe and Messi to the squad at high prices. But PSG did not have an experienced coach. As a result, PSG team could not perform well in the Champions League platform as expected. Now PSG has an experienced coach like Luis Enrique. But PSG's squad is not strong enough this season.
Luis Enrique is trying to form a youth-based squad. PSG's squad has talented players. However, the experienced players in the squad are very few. However, if Luis Enrique can succeed, I believe he will be able to strengthen the PSG team even more next season. With the help of Luis Enrique, PSG team may be able to do well in the Champions League in the coming season.
