Marseille will face PSG in mid-October. This is PSG's home match. If Marseille manages to beat PSG in this match then I would say Marseille is a worthy contender for this season's title. If PSG wins against Marseille then we will see PSG dominate this season as in previous seasons. And PSG will win the title at the end of the season. Personally, I think Marseille will lose their consistency very quickly and start going down the points table.
It looks like Marseille will find a tough opponent in mid-October because of their several meetings last season (20/21 and 21/22). Marseille have only won once when they played at PSG and drew once when they played at home in 2021. So this is a very tough opponent for Marseille because they have lost so many times against PSG, and it would be amazing if this season Marseille were able to make the difference through their best performance by beating PSG.
