John Tshibumbu scored for a second successive game as Gazelec Ajaccio came from behind to draw 1-1 with out-of-form Nantes.Following a goalless first half, it was Les Canaris who drew first blood when Alejandro Bedoya's cross found Emiliano Sala at the back post and the former Bordeaux man headed home.The visitors could not hold onto their lead, though, as Tshibumbu volleyed home from close range after substitute Louis Poggi picked him out inside the area.A point for the Corsican outfit ensured their unbeaten run was extended to seven games, leaving them two points above the bottom three.
