PSG is now dominating the competition with its very consistent performance. It was fucking crazy to see that monaco and nice were just declining so hard in matter of few weeks.
What Nice and Monaco lack is consistency in play. I think it is normal that underdogs rule the league at the start of last season then their results decline as the season progresses. This can happen because the underdog team usually does not have enough squad depth to maintain consistency in play. Injuries and fatigue are what underdogs suffer from and when that time comes, they will struggle in the second half of the season.
Yes, that's the problem experienced by underdog teams. However, PSG's dominance is still very strong in Ligue 1. No team in Ligue 1 has as good a squad depth as PSG. because they always have large funds to bring in top European players.
Ligue 1 might be more attractive when big investors come to invest in one or several clubs in Ligue 1. So PSG's dominance might be disrupted when they get an equally strong competitor.
Even though they can't be consistent, what Nice has shown so far has been very good. they proved that they can recover like the 2015 and 2016 seasons. At least they are always in the top 5 of the standings.
