Surviving in Ligue One is simple, there are limited challenges for Les Parisiens and that put then in a better position to win matches and titles because they're top club. If PSG could sit in the position to duplicate Kylian Mbappe, they will without hesitation, winning will become constant. Paris Saint Germain have risen from the top lead, they have started to settle for lesser outcome which weigh below their standards.
Currently, PSG actually does not have any problems or very serious arrivals, especially in bringing in the players they are targeting because they do have money and there are no problems with their finances. but the problem is that sometimes PSG faces conditions that are quite difficult to overcome when they play in the UCL. There have been many opportunities for PSG to really strengthen this. It should have been measured, not just differences, because after all, in the French League, no one could compete with PSG's dominance. Now, the conditions are very different when PSG are in the UCL, especially now that they have entered zone 16, which incidentally would usually be an even tougher match.
