Dimitri Payet netted his fourth goal in 11 Ligue 1 games for Marseille when he added his side's final goal in Sunday's 4-0 win over Saint-Etienne.
Florian Thauvin netted twice while Bafetimbi Gomes also struck before Payet brought an end to a quick attack as Marseille made it seven games in a row unbeaten.
Rudi Garcia's men are sixth in the league, three points behind Lyon, who occupy the last Europa League spot.
