What happened with PSG and Chelsea has nothing to do with the league itself, it will not make PSG crumble or change, they will get the league title again. What it could do maybe impact UCL for PSG , because whatever happened there, could be something they should be caring about during the UCL period, if Chelsea figured out a way to beat PSG then it would mean they could do it again, and other teams could fix it too.
But when it comes to Ligue 1, there are no teams that can beat PSG, and the league will be won by them with ease yet again. It's boring I know, I mean who would want to see the same team win it over and over again, makes it very boring, but do we have any other alternatives? Like what are we suppose to do? Just kick them out of the league? They are rich and they are strong, so they win, it is not their job to level it out, it's other teams job to get as good or at least as rich.
Returning to the French Ligue 1, it's clear that no Ligue 1 club is as strong or as good as PSG. To date, no club has been able to challenge PSG's dominance in the domestic league. However, moving on to the Champions League, they face strong clubs from other leagues, particularly Liverpool, one of the English clubs they defeated in the round of 16. Liverpool is currently working to strengthen its squad by bringing in top players. This season, we'll also see Chelsea return to the Champions League. PSG's crushing defeat in the Club World Cup final is still fresh in our minds. So, even though PSG defeated the Premier League's top clubs last season, they'll need to be even more cautious and cautious when facing any English club again, especially when they face Liverpool and Chelsea.
Returning to the French Ligue 1, as long as the financial situation of the clubs playing in it isn't as good as PSG's, it will be quite difficult to make the league more competitive. And sometimes, for most Ligue 1 clubs, not only can they attract top talent with large transfer fees and salaries, but even retaining their best talent can be quite difficult.
