Yesterday's home defeat against Eintracht in the Champions League showed just how weak Marseille are. Marseille have shown a good streak of results but it is clear that they will not have the strength to continue at the same level as PSG all season - unexpected results like yesterday will happen in Ligue 1. And even if, due to some miracle, Marseille can share points in face-to-face meetings with PSG, I am sure that by the middle of the season, Marseille will lag behind PSG very much.
What happened to Marseille yesterday can happen to any team regardless of their form at the moment. Marseille enjoyed more possession of ball in the game but failed to utilize their chances to score goals but I don't think their defeat is as a result of their weaknesses rather I think the luck was not on their side in the game at such they couldn't score a goal. With the performance shown so far by Marseille in Ligue1, I don't think the team is going to drop points even though they face PSG which is their biggest problem in the league right now, they can go all the way to beat PSG when they face each other If they attack very well and do well in their defense line.
I still think that people are overrating this Marseille team, I mean they are of course not terrible and of course they can be second, each year we see a different team be a beast and they look like they have the biggest chance to be second.
However, the fact that some people expect them to beat PSG is a bit beyond what they should be capable of. It would be awesome for them if they can achieve it of course, but I do not think that they would be able to achieve such a thing and they would lose the league title if you ask me. However a good progress continentally and being second in the league all equals to a good amount of money, which could be sustained success if they use it well enough.
