Girondins de Bordeaux suffered their first Ligue 1 defeat of the season when a Florian Thauvin brace inspired promoted SC Bastia to a 3-1 win on Sunday.
Bordeaux, who were unbeaten in their first nine league matches, threatened a comeback in the first half, but the Corsican side had more in the tank after the break.
Thauvin put the hosts ahead after just six minutes when he fired home from close range after benefiting from some terrible defending.
He then made it 2-0 11 minutes later, poking the ball home after Cedric Carrasso deflected a Toifilou Maoulida cross into his path.
Yoan Gouffran pulled one back for the visitors on the half-hour mark. His volley was parried away by goalkeeper Magno Novaes, but the midfielder followed up to slot home with his second attempt.
Wahbi Khazri curled a free-kick into the top corner to make it 3-1 in the 56th minute.
The clash between third-placed Olympique de Marseille and fourth-placed Olympique Lyonnais was postponed because of strong winds.
Earlier, Lorient avoided their second consecutive defeat when Gilles Sunu’s last-gap goal salvaged a 4-4 comeback draw at home against AC Ajaccio.
Lorient were 4-1 down at halftime after Chahir Belghazouani, Adrian Mutu and Eduardo’s brace had put the visitors firmly in command.
The home side, who had been thrashed 6-1 at Valenciennes the previous weekend, reduced the arrears thanks to Jeremie Aliadiere’s brace and they snatched a point when Sunu volleyed home four minutes into stoppage-time.
