no team is the favorites in this game if you ask me. Both teams are close enough to each other for the whole season that right now only 1 point separates them and this is why we will have to wait and see who could win.
Just like you, I also think that there is no favorite in this match as in my previous response that we will most likely see a draw. But if we look at the betting market, RC Lens is the favorite here.
That's because in their meeting they managed to beat Marseille and this time they will play at home, maybe people think Lens will win even by 2 goals. Whatever it is, I choose to avoid betting on this match because there are so many considerations.
This match, Lens versus Marseille, is going to be almost like a decider of which team is going to be in the second position of the table. I also agree with everyone here that there is not going to be a favourite in this match. I am also not going to be surprised if this is a draw. But I would expect both of them to go for the win. There is also no chance to actually differentiate these teams based on goal difference because that is also very close for both of these teams. Honestly, I just want this match to be competitive which I am quite sure that this match is actually going to be.
