Burak Yilmaz scored an early penalty and added a superb long strike as French league leaders Lille won 3-0 at Lens on Friday to move four points ahead of Paris Saint-Germain.
PSG must beat Rennes on Sunday to stay within one point of Lille.
But even if defending champions PSG win at Rennes, who are chasing fifth place and a Europa League spot, Lille can seal a first title in 10 years by winning the last two games.
Yilmaz took his total to 15 league goals since joining from Istanbul side Besiktas last summer.
He struck with a penalty in the fourth minute and spun outside the penalty area to clip a brilliant dipping shot into the top corner in the 40th, moments after Lens midfielder Clement Michelin was sent off for a second yellow card.
Canada forward Jonathan David grabbed his 12th of the campaign with a sharp finish on the hour mark.
Lens dropped to sixth place to trail fifth-placed Marseille on goal difference and are only two points ahead of seventh-placed Rennes, having played one game more than both sides.
