A day after Paris Saint-Germain increased its lead to four points by beating Toulouse 3-1, Lens endured an off night and was overwhelmed by northern rival Lille 3-0, losing ground in the Ligue 1 title race.
PSG is in an ideal position to retain its league title as it has a game in hand over second-placed Lens going into the final rounds.
Match Interrupted by Discriminatory Chanting
The game was halted in the 35th minute and the announcer at Stade Pierre-Mauroy urged the Lille fans to stop the insults hurled at their opponents. The referee threatened to take the players back to the dressing room.
Lille's Goals
Hákon Haraldsson put the host ahead just before the interval, finishing a swift move sparked by a long, precise pass from Lille captain Aïssa Mandi. Fernandez-Pardo burst down the left flank then slipped the ball between two defenders and found the unmarked Haraldsson at the far post.
An embarrassing mix-up led to Lille's second goal. Matthieu Udol's poor back pass was intercepted by Felix Correia after Nidal Celik let the ball run. The Portuguese winger was quicker to the ball than goalkeeper Robin Risser and scored in an empty net in the 50th.
Lens later was awarded a penalty after Ismaëlo Ganiou handled the ball in the box. Fernandez-Pardo wrongfooted Risser from the spot to put the Derby du Nord firmly beyond Lens.
