Marseille's poor run of form continued in a gritty 0-0 draw at Bastia in Ligue 1 on Saturday.
Without a win in four matches, Marseille were looking to bounce back from Wednesday's 2-1 home defeat to Arsenal in the Champions League but struggled to create chances.
Centre-half Lucas Mendes tested Bastia goalkeeper Mickael Landreau with a header from a corner midway through the second half, and the visitors were unlucky not to be awarded a late penalty when substitute Saber Khalifa was tripped by defender Francois-Joseph Modesto.
The draw means Marseille remain in fourth place and trail leaders Monaco by two points and third-place Paris Saint-Germain by one.
Fifth-place Rennes beat Ajaccio 2-0 thanks to a brace from midfielder Foued Kadir. Nolan Roux scored twice for Lille in a 2-0 win at bottom-side Sochaux.
Evian came back from two down to salvage a 2-2 draw with Montpellier thanks to goals from right-back Daniel Wass and forward Moudu Sougu. Efforts from striker Victor Hugo Montano and winger Remy Cabella either side of half-time had put Montpellier in control.
Newly promoted Guingamp held Reims to a 1-1 draw. An Anthony Weber own goal gave Guingamp the lead only for Nicolas de Roussel de Preville to level just before the hour.
