I think that's not very good for some teams, meaning they should be able to provide faster progress instead of waiting longer. Like Monaco, they must be able to maintain their performance to compete aggressively again in the top rankings because if they fail to maintain their best form then they will be thrown out of the top 4 the following week.
Monaco will continue to be more consistent and try to maintain their performance until the end of the season, because in Ligue1 there are only three places for the UCL zone and I think Monaco will be aiming for one of them this season even though PSG, Nice and Brest still look quite consistent in six matches at the start of this season.
Instability in big teams is often triggered by the departure of several important players in their team, as experienced by Lens because since Openda left, they have not found a new goal machine. So this is a job for Haise to improve the quality of his players, especially on the front lines.
It won't be easy to make the front line better when the season is going on like now and everyone can see how Lens are still struggling at the bottom of the rankings. So Haise has quite a tough task this season and will try to keep his team from being relegated at the end of this season, because that is something the players and coaches need to fight for this season.
