There's no definitive answer, but Marseille is in the right momentum to match PSG points or even overtake them. Luis Enrique squad will face two tough matches in Ligue 1, against Lyon and AS Monaco. We understand that PSG will be more focused on their Champions League matches, as they aim to secure a place in the playoffs. So I think, situationally, this is the best opportunity for any Ligue 1 contender to surpass PSG, even though the chances are slim. Whatever the scenario that will happen in the future, even though PSG will continue to dominate, at least the current competition makes Ligue 1 more lively.
I doubt that would happen, I can see why people may think like that but I really doubt that will happen. I think it's clear that we are going to probably see how things will change, and PSG will start to win, they are not a team that is used to losing points for too many games in a row, they will eventually get that win. Obviously bigger shocks do happen in football, look at City and how they failed to win for so long, I mean they have just one win out of 7 games or something like that, if PSG has a period like that too, then yeah you are right Marseille could pass PSG in that situation.
But premier league is insanely competitive, even Aston Villa may win Ligue 1, or at least would be fighting for a title, whereas Ligue 1 is simple, hence why they call it farmers league. I would say PSG will not have that kind of bad stretch, they had two ties, which is enough, they will probably go back to winning now, and will not let Marseille get any closer at all.
