I am also surprised by the assumption of many people who claim that PSG is in bad shape this season, even though we know how they are still unbeaten so far in the league, indeed PSG has had negative results in some of their matches but that does not mean they are in bad shape, the only challenge for PSG so far is the champions league, while ligue 1 of course they still show their power so far, currently their chances in the champions league are still very small to qualify for the next round, so if they are early eliminated in the champions league this season, then I we will see PSG will be unstoppable in Ligue 1 later.
If this is with reference to the champions League then we can agree to saying PSG isn't in a very good form but in their domestic league it's a different case as they still remain the champions and the dominators of their domestic league, they have al of their key players intact and none lost to injury already so they probably have their fome intact on that their technical approach in the champions League isn't just the best already and so they cannot be seen as doing just so well in that aspect.
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.
