Brothers Andre and Jordan Ayew were on target as Marseille snapped a three-match winless streak on Sunday with a 2-0 win at Ajaccio to draw level on points with Ligue 1 leaders Paris Saint-Germain.
Marseille move to 22 points from 10 matches, and although their inferior goal difference sees them still trail PSG, Elie Baup's side have a game in hand on their arch-rivals.
Toulouse could leapfrog both clubs though if they beat Bordeaux by a two-goal margin in Sunday's late kick-off.
PSG saw their unbeaten start to the domestic campaign come to a halt on Saturday, as they were beaten 2-1 at home by Saint-Etienne in a game that also saw Zlatan Ibrahimovic dismissed for a dangerous challenge on goalkeeper Stephane Ruffier.
Marseille were far from their best against an Ajaccio outfit that had been unbeaten in Corsica since last December, but the result will undoubtedly have provided them with some comfort after taking just one point from a possible nine.
Andre Ayew accounted for Marseille's first league goal since October 7, as he nodded Charles Kabore's looping header beyond Guillermo Ochoa on 55 minutes after the hosts failed to properly clear their lines.
Jordan Ayew, who replaced the ineffective Loic Remy midway through the second half, then secured the points two minutes from time when he slotted low into the corner following Mathieu Valbuena's cutback.
