Marseille have failed to win 4 home games in a row, but they have also had some very serious opponents recently (Nice, PSG, Monaco).
Montpellier have excellent statistics - 5 wins and 1 draw, but the team had a fairly simple calendar (the only serious rivals were Lans, with whom Montpellier drew at home). In contrast, their head-to-head encounters with Marseille are going very poorly (4 defeats and 1 draw).
Prediction: Marseille to win. We recommend the “1 Win” bet, odds 1.5
