You're right, I agree with you Lens lost by a big margin to PSG did a bit of a disservice to their position in the points table. Now Lins will have to secure a series of consecutive victories, which will enable them to regain their place in the points table.
Lens is only one point behind Marseille in the standings at the moment and it's not a big amount for Lens to chase him back, because what is clear is difficult for Lens and Marseille to catch up with is PSG, who are currently still at the top of the standings. So Lens and Marseille only have to compete to take second place because the first place will likely belong to PSG again this season, even though the points are still possible to catch, but when it comes to the strengths in the team, I think PSG is still far more from both Lens and Marseille.
The big difference with the 72 points that PSG got and there is an 8 point difference with Marseille who are in second place, of course this makes many teams pessimistic about chasing him and I think it will also be very difficult to catch PSG at the end of this season.
We will focus on fighting for the second and third positions this season because of the difference in the points table apart from Marseille and Lens, Monaco is also worth considering because he has accumulated as many as 61 points and the position that Lens has today is also not a good position because in behind them is Monaco who are ready to overtake Lens in third place.
