Guingamp have come from a goal down to beat Ajaccio 2-1 away from home in Ligue 1, thanks to strikes from Mustapha Yatabare and Claudio Beauvue.
Ajaccio took the lead in style after only eight minutes when Paul Lasne drilled home an impressive left-footed shot from outside the box.
The hosts' advantage was not to last long, however, as Guingamp replied in the 13th minute when Yatabare was played in by Younousse Sankhare, leaving him with time and space to fire into the bottom corner.
Guingamp could have gone into half time a goal ahead, but Mana Dembele couldn't guide his effort on target following an inch-perfect cross from Jonathan Pereira.
The visitors grabbed the match-winning goal in the 74th minute through Beauvue, who got his head to a delivery from Thibault Giresse to guide the ball into the top corner.
