Ludovic Obraniak scored a 92nd-minute winner for Bordeaux's at his old club Lille after they appeared to have blown a three-goal lead to win 5-4.
Bordeaux responded to the challenge of coach Francis Gillot to turn their season around by beating the top clubs, but only just as they conceded three goals in 25 minutes to give away an apparently comfortable advantage.
The visitors led after just three minutes through Nicolas Maurice-Belay and, although David Rozehnal levelled five minutes later, Obraniak's first had them in front again by the 16th minute.
Maurice-Belay added a third four minutes into the second half before Yoan Gouffran made it 1-4 just before the hour mark.
Lille responded as Eden Hazard and then Mathieu Debuchy got them back in it, before an 89th-minute equaliser from Nolan Roux infuriated Gillot. However, Obraniak bailed out Bordeaux as he finished from close range in injury time.
