For some reason these teams are more popular in the biggest competitions, in Ligue 1 it is known that PSG is the best, for me PSG has no rival in Ligue 1, so they can win Ligue 1 quite relaxed, the only way is for them to make a difference similar to what they did or what happened in the Bundesliga, when Leverkusen surprised them with Xabi's winger, a Xabi would have to arrive at Lille, Marseille or Lyon, I think that is the only way they can change Ligue 1.
If the level of competition in Ligue 1 is not as competitive as other major leagues, then PSG will always be the best to dominate Ligue 1. There is even no pressure for PSG to defend the Ligue 1 trophy because its competitors are only competing for second place and so on. In addition to having to make major changes, maybe some clubs have to dare to take steps to recruit quality players or reliable coaches.
Ligue 1 will be more competitive when there is competition and investors must also come to this League so that many clubs will compete to make changes by taking a better approach than before in an effort to compete with PSG.
Ligue 1 is PSG birth rite, no matter how poor their performance is, they're still going to win the league. No club is strong enough to compete with PSG because they're poor. I am waiting to see the day that a different club will win Ligue 1. I don't actually watch their matches because I already know that PSG would win the league at the end.
