There is no need to be surprised by PSG performance in Ligue 1, PSG dominance is still very difficult to break by other teams, especially the trio of Messi, Neymar and Mbappe who have worked well together in PSG attack line. There is not the slightest doubt that PSG will win trophies again because other teams are very difficult to give competition to PSG.
Lens has done a great job compared to other teams, are in second place with a difference of five points from PSG making it the only team that has the closest points to PSG. However, Lens is not a team that PSG needs to worry about because the strengths of these two teams are very much different.
I totally agree with what you said, because in this case, regardless of the performance of other clubs in Ligue 1, everything is still the same because Ligue 1 will not be separated from PSG, just like the Bundesliga, which will not be separated from Bayern.
It is difficult for other clubs to make competition real in this case, especially in terms of financial strength and team quality, it is clear that the reduction is quite significant.
This season will still be the same with PSG running alone and several other clubs busy competing in the top 2-4 position.
