Lens moved back above Paris Saint-Germain into top spot in the French Ligue 1 table on Friday after a Ruben Aguilar goal secured a 1-0 win at home to struggling Le Havre.
Aguilar, a right-back capped once by France in 2020, arrived at the far post to score from a Matthieu Udol cross in first-half stoppage time on a rainy night in far northern France.
It was a welcome return to winning ways for Lens, who had recorded 10 straight victories between league and cup before a 3-1 loss last weekend in Marseille.
Lens therefore came into this match in second place in the Ligue 1 table, two points behind PSG.
The win moved them a point ahead at the summit after 20 games, even if Luis Enrique's team will be able to reclaim first place by avoiding defeat away to Strasbourg on Sunday.
