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.
There is no doubt that PSG is performing very well in Ligue 1. However, PSG's opponents in Ligue 1 are not very strong. PSG's opponents in the Champions League are very strong. And we cannot see a better performance than PSG in the Champions League. This proves that PSG is not strong enough yet. This team definitely needs more improvement.
PSG has very few experienced players. This is why PSG is not able to perform well consistently. PSG has an experienced coach. If Luis Enrique can form a squad with players according to his choice, then I think PSG will become stronger and can do well in the Champions League. I am looking forward to seeing which players Luis Enrique adds to the squad in the winter transfer window.
