PSG have the full control in the league and it really seems like this will go on for so many more years. Lille won the title too while PSG were this good. But this kind of incidents don't happen often in the end. To be able to finish the PSG dominance in the Ligue 1, some other team must be bought by rich people and the team should build a very strong squad like PSG. But we don't see this often too. I mean that we don't see many very rich clubs in every league. And the Ligue 1 is one of them.
PSG's dominance of Ligue 1 has indeed occurred in recent years after PSG ownership was taken over by Nasser Al-Khelaifi in 2011, after becoming a rich club PSG continued to dominate Ligue 1 without giving gaps to other teams in the championship competition, maybe it's just luck if last season Lille can win the french league, and i think maybe we will see at least 10 more seasons it can be repeated in ligue 1, to be honest PSG dominance in ligue 1 makes ligue 1 now quite boring to watch and we can predict that PSG will eventually become champions at the end of the season by leaving a large enough difference in points against from other team.
