Lille boss Rudi Garcia believes his table-topping side will respond positively to their recent wobble
A three-match winless run has seen their lead at the summit cut to two points, with reigning champions Marseille closing in fast.
Didier Deschamps' side also have a game in hand, meaning they could take pole position were they to prevail in their extra fixture.
Lille are refusing to panic, though, and remain confident that they can take the top flight crown.
"You measure the quality of a side on their ability to bounce back," Garcia told L'Equipe.
"This group can do that because they know what they have to do.
"We know that no team will win every match between now and the end of the season - not us, not Marseille or any other team.
"The moment performances start to slip you have to ensure that you respond well."
Lille defender Aurelien Chedjou also believes that the club are still capable of landing a first league title in 57 years.
"Nothing can trouble us and we don't feel like we are under pressure," he said.
"We want to achieve something great, but without putting ourselves under pressure.
"It is not nice when you see 'Aurelien Chedjou titles: none'.
"There are some great players that end their careers without winning a title, though, so we are lucky to be in such a positive position."
