You'd agree with me that it's not the fault of PSG that the other clubs have refused to sit up, rather they prefer to remain in the position they are in as long as when the next season comes they'd qualify for the champions league competition. Chelsea made us understand that PSG can be beaten. Bring their game to them and you'd see a confused club but not many of the other French teams want to take this bold step so when as a formidable side you don't have a competition, you would have no choice but to rule.
Understanding that PSG can be beaten is no new thing because except last season where they got epic in their performance, PSG has not been a great champions league team except that they always have an appearance in the champions league every season. In Ligue 1 other teams have been unable to bring to PSG some sort of challenge where they will be played with their own style and I see that the PSG dominance in the Ligue 1 can be used as advantage by other teams but they probably do not know how to use it.
