Benjamin Corgnet netted an extra-time winner to help Saint-Etienne to a 2-1 win over Ajaccio in Thursday's Coupe de France last-32 encounter.
Christophe Galtier's men started the match in fine fashion and needed only 10 minutes to open the scoring. Jean-Christophe Bahebec beat his marker to the ball after Valentin Eysseric's corner and headed home from close range to make it 1-0.
There were chances for Neal Maupay, Nolan Roux and again Bahebeck in the remainder of the first half, but Riffi Mandanda proved to be too much of obstacle between the sticks.
