Marseille rose to second spot on the Ligue 1 table after a narrow 1-0 win over Lille at the Stade Velodrome on Sunday.
Jordan Ayew headed home a Mathieu Valbuena cross immediately after half-time to send the home side ahead and from there they held on to record their eighth win of the season.
Marseille now sit behind league leaders Paris Saint-Germain on goal difference, while Lille drop to ninth having now lost their last two games in Ligue 1.
Fellow title hopefuls Lyon missed the opportunity to stay top of the table after they were surprisingly beaten 3-0 by Toulouse at the Stadium Municipal.
All of the goals came in the second half, with Toulouse midfielder Wissam Ben Yedder playing a starring role for his side.
The 22-year-old opened the scoring on 50 minutes before doubling his side’s advantage with three minutes left.
The French Under-21 international capped off an impressive performance by assisting Etienne Capoue for his 90th minute goal in what was an important win for the home side.
Lyon now drop to fourth on the table while Toulouse are just three points behind Remi Garde’s seventh-placed men in what is proving to be a typically congested French top flight.
In the day’s other fixture Bordeaux also lost ground on the frontrunners after they lost 1-0 away to Montpellier.
After going into the weekend in second position Francis Gillot’s side were keen to add to their five-game winning streak but could not overcome a resilient Montpellier side, who won the game thanks to a Remy Cabella goal in the 69th minute.
The loss sees Bordeaux drop out of the European places while Montpellier rise to 12th after breaking a run of three successive draws.
