PSG host Lens and the result of this match is very important for both teams. There is a six-point gap between the two teams and it will either increase or decrease with this match. It is a match that will perhaps decide the fate of the league. For this reason, I think all teams will focus on this match. The result of this match will also be important for Marseille and Monaco. They are the teams competing for 2nd place.
I won't be surprised at all if I see PSG lose this game against Lens both teams are on top of the table and Lens should itself in this game by winning this important match against PSG and if they somehow beat PSG the gap between these two teams can be decreased to three points which can put PSG in danger.
Psg will not allow Lenz to have a win against them. The best result of Lenz in that match will be draw. If you check very well 6 points difference is not large enough, if Lenz closes it to 3 points, this will force pressure on the PSG team.
From the other Angle, if Lenz losses tonight, it will give Marseille a chance of catching up with Lenz at the first position. So, it will be a tough display between the two clubs.
