Nancy recorded a valuable away victory over Brest as they continue to fight to stay in Ligue 1.
The hosts started brightly and went close early on when Eden Ben Basat linked up with Bruno Grougi to create an opening for Mario Licka, whose 25 yard shot whistled past the post.
As the first half wore on, it was Nancy who began to boss the game and they took the lead after 18 minutes.
Bakary Traore opened the scoring when Massadio Haidara had burst into the area and teed the ball up for him to strike low into the net.
Djamel Bakar could have made it 2-0 in the 68th minute had it not been for the brilliance of Brest goalkeeper Steve Elana.
The striker's vicious left-footed drive looked destined for the top corner before Elana's magnificent flying stop.
Brest could not draw any inspiration from their keeper's efforts and Nancy went onto win and climb to 12th in Ligue 1.
