Paris Saint-Germain is a superior club in Ligue 1, so it is natural that almost everyone predicts that they will be able to become champions in Ligue 1 again. The percentage is not 100%, but when compared to other clubs, their chances of becoming champions are very high.
While in the Champions League they always have difficulty becoming champions, even their best achievement was only being runner-up and if I'm not mistaken they have only done it once. This new format will also be more troublesome, because to be in the last 16, 16 teams must go through the play-off round and only 8 clubs can automatically qualify. I don't know yet whether this benefits them or not, because in the next round it will be as usual, while they also often fail in the knockout round.
Although not 100% but 99% PSG can hold the title again this season without having to doubt it because as long as no team has made a big transfer to bring in professional players with high quality talent, I am sure PSG can dominate league 1. And related to competing in the UCL, with the current new system even weak teams have the opportunity to get lucky to qualify for the last 16. While PSG still has a good enough performance to try their luck in this new system as long as Enrique is able to implement the right strategy. Dembele and Kolo Muani are very productive and very reliable.
The way PSG have been performing in the local league tournament and with the squad they still have, they can win the title by a big margin. I mean, at the end of the season, PSG's points gap with the team that will be PSG's closest rival will be much higher.
In the French league we have not seen or are yet to see a team that can compete with PSG. However, even if PSG is not concerned about doing well in the local league tournament, their main concern is the Champions League. But currently PSG management and PSG manager in the role they are in it seems they are not thinking about the Champions League tournament as they have not bought any player so far or strong position on buying any player. The transfer market may be closed in a short time and no team will be able to buy any player even if they want to.
If PSG is thinking about the Champions League then they must add quality players to their club.
