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.
PSG and Chelsea may meet again in the champions league and when they do, it will be a tough game and a very great challenge for them both. As one team is looking to have a revenge, the other team will be looking to uphold their prestige on them, which will make the match very tough. Champions league is the only place that PSG will find difficulty to triumph, as for the Ligue 1 competition, they will still win it again no doubt about that.
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.
It is not as easy as it seems though. Having a whole change in a team and having the chance to be at a position to beat PSG to win the title is not an easy task. It means that any team that could stand that chance will have a new owner who can spend as much as PSG does to buy big players in the team because that’s the only way PSG can be defeated as they’re untouchable when it come to the Ligue 1 title.
