Marseille goalkeeper Steve Mandanda has admitted that winning the Ligue 1 title this season will be "difficult" for his side.
The former French champions fell nine points behind leaders Paris Saint-Germain on Sunday as they were held to a goalless draw by Lille away from home.
"It was important not to lose against Lille because they are a good side and are trying to catch up with us in the table," he told Le Parisien.
"There are still six games to go and the objective is to consolidate second place - Paris are nine points ahead, so it will be difficult to catch them now."
Lyon are two points behind Marseille in third place in the league table.
