PSG can claim the French Ligue title much early before the season comes to an end. I doubt there is any team team that can stop them from winning the French Ligue title. Both Marseille and Monaco has been in form form this season but I don't think they can compete with PSG for the title.
That's what makes this league not so interesting because PSG can claim the title much earlier before the season ends so the league competition is not so competitive. It is difficult for any team to break PSG's dominance and that is not at all the competition that football lovers expect. To be a competitor for PSG in the fight for the title, it takes a balanced player strength and that is not possessed by Marseille or Monaco so it is difficult for both of them to compete with PSG.
You have a point, I just don't like it when there are no competitions in football leagues. This season too, we all know the winner already when we still have months to the end of the season, it shouldn't always be like that, fierce competition keenly competed is always interesting. Still, I absolve PSG from any wrongdoing but rather commend them for holding that top position for too many years while others look on. It's now a wake-up challenge to other clubs in the league, they can buy players and change coaches. PSG doesn't have two heads so they should be ready to break the jinx like what is happening in Serie A.
