Lille - who have averaged almost two goals per game in a tight league where Olympique Marseille could also snatch the title - have a four-point cushion and want to make sure they do not lose their advantage when they travel to mid-table St Etienne on Tuesday.
"There are four games left and if we are to win them 1-0, I'm OK with it, no problem," defender Mathieu Debuchy told reporters after his team beat Nancy 1-0 at the weekend.
"Nobody will remember how we grabbed our points."
Debuchy explained that Lille's priority is now to play solidly and not attractively.
"At Nancy, we did not play our best game of the season but we were solid from the start until the end and this is how it is going to be until the end of the season," he said.
"It is still doable, even if it is less than a week ago," coach Didier Deschamps said ahead of the champions' home game against Stade Brest on Wednesday.
"I still believe we can do it."
"We still have four games left and if we win them all, we may be doing better (then third)," midfielder Miralem Pjanic told reporters.
