I think that PSG are not too worried about Ligue 1 because they are almost certain they can win it without much competition. That’s why their approach to Ligue 1 games is more relaxed, especially since it’s only the start of the season. It’s clear that the team hasn’t yet reached their maximum condition, which is why the wins may be less convincing. Although, as you said, even a one-goal victory is still 3 points.
There is no reason to worry too much about Ligue 1. There is no squad that can challenge PSG for the title. Every team is quite feeble compared to PSG. and their performance is very inconsistent.
We considered marseille as a worthy contender for the title. But they lost against Rennes in the first match. Now monaco seems to be a bit stronger . But it does not seem that the team will be able to do well in the long run.
Luis enrique will probably focus on the Champions league matches. There is no doubt that the team will be a contestant for the Champions League title this season as well. Even PSG's squad is quite stable. We saw psg win by a small margin in the first match of ligue 1. PSG gave their young players a chance in this match. If they played with their main squad, they would have been able to win this match by a large margin.
