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.
PSG has already dominated Ligue 1, we can’t deny that. However, that doesn’t mean if Chelsea were successful the first time, they will keep beating PSG continuously. Football is just a game of strategy.
If PSG can create another good strategy, they will still be strong again because they have what it takes. Their main focus will likely be the Champions League, as they know they have less to worry about in Ligue 1.
They are aware that no other team is likely to be a serious threat or match them in points, since it’s all about consistency. So, they will aim to accumulate a lot of points early and then focus fully on the Champions League.
This will make it easier for them to perform better in Europe. I won’t say they will definitely win the trophy, but I believe they will do better, and possibly make it to the semifinals in the upcoming season.
