even-time reigning champions Lyon, who are away at Le Mans on Saturday, top the table with nine rounds of fixtures left but they are just a point clear of Marseille, with Bordeaux a further two points back.
Les Gones are still considered favourites to land what would be a record eighth consecutive crown but they have won just one of their last four matches.
This weekend's match should be one of their easier games between now and the end of the season as they still have the likes of OM, Bordeaux, Paris Saint-Germain and Toulouse yet to play.
"If we are going to win the title, we'll have to produce a great end to the season," said Lyon forward Ederson.
