No one denies PSG's performance in the Champions League this season, they are very visible experiencing many problems that make it difficult to achieve victory. in Lique 1 PSG is a superior team, they have not even experienced defeat. for me PSG's problem is not in the system, or technical approach, but the quality of the PSG players themselves. in particular, they do not have a reliable finisher with at least 1 goal per match. in fact, the wingers are the ones who score more goals, even though they have a center forward. now Goncalo Ramos has returned, we will see how far he contributes to his team. actually PSG has good players, they also usually always dominate the course of the match. but it will be useless, if the players cannot complete the final finish by scoring goals. okay in Lique 1 they were productive, but in the Champions League they were confused. even so, PSG eventually won the match over RB Leipzig.
PSG are really horrible in the Champions League indeed. They might even risk their chance for the playoffs you know.

The team are still not ready for such tournament as it seems. At first I didn't think so honestly.
There are really talented youngsters in the squad but they are still not exactly a team. I can say they are good only in the Ligue 1. Even here they started to get poor results recently.
I think they will win the Ligue 1 title anyway. However I don't expect them to be competitive for the Champions League one. But I assume they wouldn't say goodbye in league phase at least.
