PSG has dominated that league so widely with a strong grip and I don't think others outside the league will even support other wise I mean they use to be a time when lille was kinda trying to compete with them or the likes of Marseille and Lyon but all those teams too are no match compared to what PSG have built in that league and it will only take a football miracle to see another team win that League.
They have been simply too strong while other clubs in Ligue 1 have been too weak, less competitive than PSG. Together those factors resulted in strong domination of PSG in Ligue 1 over latest years in about a decade. This won't change in the near future with all latest actitivies in PSG and other French clubs.
At this point I think PSG has dominated the league long enough that it has made the league become boring to watch because every season it is very easy to predict the winner of the league before the beginning of the season which is why some people now regard the league as farmers league. There is less competition in the league the teams that are supposed to challenge PSG don't have the squad they have it's making it difficult for them to stand against them cause PSG keeps getting better and better every season it will be difficult to see another team coming up to overcome them but they have to make it happen if they don't want their fans to get tired of watching them.
Before PSG, there was Lyon that dominated Ligue 1 in about a decade but Lyon was not a big and rich club like PSG. They dominated Ligue 1 by very successful player transfer strategy that worked super well for them in nearly a decade. After that, this strategy no longer worked well for Lyon and their domination disappeared while PSG domination in Ligue 1 mainly comes from their abundant finance. Surely this abundance in finance can disappear in future and it will have great impact on PSG domination in the league. In the near future, it won't happen I think so and their super great performances last season don't give me any reason to think that PSG will fail to win Ligue 1 title again this season.
