Considering Lens, it is true that they could not show the performance they expected at the beginning of the year, but their performance is gradually increasing. They had gained morale especially after the Arsenal win. They drew 1-1 with PSV yesterday. They still have a chance to get out of the group and they will want to advance to the next round by winning the other matches they will play. In the French league, they will try to win matches by reflecting their energy on the field. I think luck will slowly turn for Lens.
This season seems to be a season that is quite surprising for Lens because it is indeed with a fairly busy schedule that makes them definitely difficult so that this has an impact on performance.
In the current domestic competition they can only win 2 out of 9 matches played and this is clearly inversely proportional to their performance last season which was very good at the beginning and even until the end of the season but I think when their focus begins to narrow imo they can still rise only for now they are still difficult to do that because in the end there are still several competitions they have to live in close proximity.
At the moment it's likely they will still focus on the Champions League regardless of what the final result is but they will definitely use this as their capital to get better but indeed for Ligue 1 I think they can still rise in the middle of the season later.
