Paris Saint-Germain (PSG) have remained undefeated in Ligue 1 Round 19, as they continue to lead the table with 26 points from their first 18 matches. The French giants have been impressive throughout the season and are currently the top team in the league.

On the other hand, Lens has also made some progress in recent weeks. They have managed to keep a clean sheet in two consecutive games, which is a significant achievement for any team. However, they remain just one point behind PSG and will be looking to pick up another three points against Reims on Sunday.

Despite being only four points behind the leaders, Lens have struggled at home this season. They have lost five of their eight away games, while they have won just one of their six home matches. This could be a major problem for them if they want to challenge for a European place next season.

Overall, it seems that PSG's dominance in Ligue 1 remains intact. They have shown their class time and again, and will likely continue to do so until the end of the season. On the other hand, Lens' form at home will be closely watched, as they look to mount a serious challenge for a Europa League spot.
