It's not bad, but it's not good either. I think they are still lucky when they are in 6th place now, why? in my opinion they are in the current position because other clubs have performances that are not better than them. Their performance at the end of last season they carried over to this season, last season in their last 5 matches, Marseille could only record 1 win, while for 4 other matches they had to lose, that made them lose the competition with Lens last season.
But when compared to Lens, this season Lens is so bad that they even have to be thrown to 14th place in the standings.
In the next match, both of them will face opponents who are quite different in terms of their performance this season. Lens will face an opponent who is one level above at the moment, namely Le Havre, which this season was promoted to Ligue1, so Lens must be able to take advantage of this opportunity to get full points at home to Le Havre. Meanwhile, Marseille will face Nice, who are currently runners-up in the Ligue1 standings, so it might be a little difficult for Marseille to win at Nice's home ground.
