Rennes pulled off the biggest surprise of Saturday's Ligue 1 fixtures as they won 2-1 at title-hopefuls Lyon, while Bastia and Angers continued their strong starts.
Pedro Henrique gave the visitors an early lead before Nabil Fekir restored parity for Lyon but Mehdi Zeffane came back to haunt his former club by restoring Rennes' advantage on 55 minutes and they held on for the win.
The home fans made their disapproval clear as they booed last season's Ligue 1 top-scorer Alexandre Lacazette when he was replaced on the hour-mark.
Bastia were Saturday's biggest winners, meanwhile, trouncing struggling Guingamp 3-0 to move up to second, with Julian Palmieri and Lassana Coulibaly finding the net to add to an own goal from Maxime Baca.
And surprise packet Angers round out the top three following an impressive 2-0 victory at GFC Ajaccio, a brace from Cheikh N'Doye proving enough to down the Corsican side.
Thomas Lemar earned a point for Leonardo Jardim's men when he came off the bench and fired home a low shot midway through the second half, while in Nice, Caen dropped to sixth after suffering their first loss of the campaign - going down 2-1 to the home team.
