With Mbappe or without Mbappe they can still dominate Ligue 1 in my opinion. But the highlight for me was when they relied too much on Mbappe when they had him, so maybe that will have a little influence, because they will go through a transition process for the position left by Mbappe. But I hope they won't have any problems with it.
Most of the Ligue 1 teams fail to understand that even with all the might of PSG they can still be challenged and possibly be won in the challenge especially if they are able to build a very well coordinates and organized team that will build a very solid stamina and strength such rhst whenever they get to meet PSG , the quality of players in PSG will not be of so much or great influence on them, just like we see in the bundesliga where we see that Leverkusen isn't the best with their depth or form but they were able to build a formidable team that even the best struggled in fixtures against them in the bundesliga this season.
The reign of PSG dominance in the Ligue 1 seem to be having a possible end soon because I can see that mbappe leaving is looking like something that's going to affect them Ina way and finding a good substitute around it is really going to be challenging and that alone is beginning to sound like a problem to them which may take awhile for them to tackle which will in turn be an opportunity for other teams in the Ligue 1 to take advantage and before the recovery they would have been able to set a standard ahead of PSG.
