We have been noticing PSG's weakness in defense and weakness in midfield for a long time. The weaknesses that we as ordinary supporters are clearly noticing may not be visible to the PSG management. If the management could see where PSG's weaknesses are, then maybe the management would have improved in that area. You go to war only your air force is strong but your defense is not strong so no matter how much you attack with air force the opponent will enter your area and destroy your area. First you should secure your own area without attacking other's area, when your own area is secured then your performance in other's area will be better.
We have clubs that are doing exceptionally brilliant and also clubs that are struggling. Everything will play out nicely whenever PSG falls back to formidable action in Ligue One, but their main focus is top tournament like the UEFA Champions League. PSG are strong enough because they have the necessary players available but It happens this team doesn't have the ginger morale to top their game. Paris Saint-Germain have weaknesses and its their defendlines, they're unable to match up with strong competitive race but Luis Enrique is working on this weaknesses to enable him and his team become promising in tournaments.
It's actually quite boring when talking about them in Ligue 1, yes that's because there are no clubs that can be at the same level as them. I agree that their competition is actually on the European stage, there we can see the extent of their strength because the majority of the clubs they face there are at the same level or even better than Paris Saint Germain. It is proven that they always have difficulties when playing in big competitions like the Champions League, this shows their true quality which we don't see in Ligue 1.
I'm always pessimistic when I see them, not because I underestimate them, but everything I feel is born every time I see their appearance. I think Ligue 1 is too easy for them, but that ease still makes it difficult for them. Ligue 1 and Champions League are 2 different levels, so I prefer to judge them when they are in the Champions League.
