Striker Majeed Waris scored his fifth league goal of the season in Wednesday's 3-2 win over Paris-Saint Germain in the Ligue 1.
Thilo Kehrer was caught out by Coulibaly, who moved into the box before picking out Samuel Moutoussamy — the midfielder miscued his shot.
But it served Majeed Waris perfectly, and the Ghana international finished from close range in 44th minute to celebrate his 100th Ligue 1 Conforama appearance in style.
PSG's veteran Italian goalkeeper Buffon denied Waris a brace and hist team's fourth in the 67th minute before PSG rallied.
