It was really important to win this game to take the second position in the standings back from Lens as well. These two teams still have a similar form to each other on the recent weeks so the balances can be upset anytime again. Marseille should just focus on benefiting from the quality advantage.
Lens-Marsielle game on May 6th could decide who wins that 2nd place and direct qualification for CL. Imho, I think that Lens is in a better form at the moment and is more likely to finish 2nd, despirte Marseille objectively having stronger team.
In this match, I will put the team ahead in Marseille. Because I saw the performance of the last few matches in Marseille. They are playing very well. They have won the last two matches against Troyes and Lyon. Both teams were strong. And they will play against Auxerre in the next match. Although this team is at the bottom of the points table, the team is in very good form. I guess Marseille will be able to continue their winning streak. They will win against Auxerre and Lens and they will be able to tighten the second place in the points table.
Marseille in their meeting with Lens will act as guests, so this is an advantage for Lens to be able to take advantage of the atmosphere at their home turf. But that doesn't mean it will be an easy match for Lens or Marseille. It is difficult of course to determine who will be the winner because in strength they are not much different. A draw is also very likely to occur in a big match like this.
