Lille and Marseille played out a lacklustre goalless draw in the Ligue 1 on Friday.
The result left Marseille fifth in the standings, 22 points off leader Monaco's pace, with Lille lagging 34 points behind.
The hosts had the match's best chance with six minutes left but Eder's headed effort was parried away off the crossbar by goalkeeper Yohann Pele.
The game marked Marseille manager Rudi Garcia's return to his former club.
Lille is managed by Franck Passi, the man Garcia replaced at Marseille after American billionaire Frank McCourt's takeover.
Garcia spent five years as Lille coach, leading the club to a league and cup double in 2011. He went on to coach Roma in Serie A.
Metz ended a five-match winless run to move seven points clear of the relegation zone with a 1-0 win against Bastia.
The hosts had the best chances and forced Bastia keeper Jean-Louis Leca into a couple of good saves before Gilles Cioni scored an own goal in the 47th minute when Lindsay Rose's clearance hit the defender and went in.
Bastia had only three shots during the whole game and none of them was on target. The Corsican side remain in the danger zone, three points above last-placed Lorient.
