This is why the Ligue 1 is very boring as well. There is literally no competition for the league title most of the time. It is all because of one team being bought by rich people and the others' looking at them from a far point. I'm not even sure about whether this would change in this league in the future either.
One thing PSG enjoys the most has to be their financial strength as it has really been a huge strength for them such that they have the purchasing power to get almost any player they want to be in their team provided such player is up for sale, that has been one of their biggest advantage over all other Ligue 1 teams and they have aswell been able to strengthen their team so much that they have an unparalleled matching strength with most of those other teams in the Ligue 1 so most definitely they have they ability and capacity to win these teams and reducing the chances of them been pressured into have challenges with the Ligue 1 games.
But then one of the strong hood of PSG has been in one of their key player mbappe, and by next season he will be leaving i think that too may have an effect on the team and they may likely not be able to enjoy the dominance they had enjoyed all along because it may be challenged by others knowing they don't have that strength again but then if the rumors of them sorting after osimhen is true then they may just be having a good replacement.
