The results of losing and drawing in the last two matches worsened the situation that at the beginning of the season played consistently and now a little out of control, but Marseille also played badly they were often punished with red cards and yellow cards in every match and I think they are too emotional can not control the game because of the pressure they have to face with violence, I think they need time to recover and the next match away I doubt they can produce 3 full points even though their opponents are below them.
Marseille was previously able to perform quite consistently, but for some reason suddenly they crashed when they were in pretty good form at the beginning of the season, the loss to Strasbourg was actually the beginning of their inconsistency including when they had to get a draw from the anger in the previous match, so I think maybe it will also affect them when they have to face Montpellier in the match, I saw in the match against Angers that it was seen that the Marseille players were unable to control their emotions and in the so actually harmed themselves, so I think it is a problem that De Zerbi must immediately overcome at this time.
For now Marseille is still in the top three after playing seven matches with a score of 14 points and that is certainly not a bad result for a team like Marseille because currently the team is only three points behind PSG and five points from Monaco who are at the top of the standings. And for the next match I think Marseille could win again because considering their opponents are not strong enough even though Marseille will be the away team in the match. However, head to head I have not seen Montpellier able to beat Marseille in Ligue1.
If you look at the head-to-head record between Marseille and Montpellier so far, they are still quite ahead of Montpellier with the last 31 meetings, Marseille won 16 times, while Montpellier only won 7 times, while the two teams draw in 8 matches so far, So this shows that Marseille has a good enough chance to win even though they play away later, but even so, of course it is important for Marseille to improve their current form if they don't want to get bad results like against Strasbourg and Angers.
