Brothers Andre Ayew and Jordan Ayew set up goals that gave Marseille a 2-0 victory at Rennes on Friday to keep the pressure on French league leader Lille.
Loic Remy and Lucho Gonzalez finished the opportunities set up by the Ghana internationals that kept them in the hunt of retaining the title.
Andre and Jordan Ayew set up a goal in each half as Marseille moved to within one point of Lille, before the rest of the weekend games.
Rennes is second and has the same points as Lille, which leads on goal difference.
Remy scored his eighth league goal of the season with a diving header from Andre Ayew's cross in the 23rd minute.
Jordan set up Gonzalez in the 80th to end Rennes' run of five straight league wins.
