Saint-Etienne went top of France's Ligue 1 on Saturday with a 3-1 win at Valenciennes as Benjamin Corgent grabbed a brace.
Corgnet's brace came on either side of Romain Hamouma's strike for Les Verts before Maor Melikson grabbed a consolation for the hosts from the penalty spot ten minutes from time.
It was enough to move Saint-Etienne a point above Paris Saint-Germain at the top of Ligue 1 following the champions' 2-0 win at Bordeaux on Friday.
Big-spending Monaco could go back to the summit if they win at home to Lorient on Sunday.
New Turkish attacking signing Mevlut Erding, formerly of PSG, may have drawn a blank but his supporting act stepped up to the mark in fine style.
Corgnet slotted into an empty net in the 17th minute after home goalkeeper Nicolas Penneteau had denied Hamouma.
The latter then doubled the advantage in the 47th minute, beating Penneteau with a fine strike from 20 yards.
Corgnet wrapped up the victory with a shot through Penneteau's legs from Hamouma's cross six minutes later.
Valenciennes' sole response came from a generously-awarded penalty when the referee whistled for a handball against Bayal Sall.
Marseille draw in Toulouse
Marseille's hopes of returning to the French Ligue 1 summit were hit by a 1-1 draw at lowly Toulouse on Saturday.
In fact, the former European champions needed a late goal from Brazilian defender Lucas Mendes to snatch a point against the team that begun the day bottom of the league.
Marseille had led the standings two weeks ago before being overhauled by Monaco, who won 2-1 at the Velodrome in their last match before the international break, and then by Paris Saint-Germain, who won 2-0 at Bordeaux on Friday night.
But the team from the Cote d'Azur could have regained top spot with a victory.
That looked a likely scenario throughout as Marseille created, and squandered, several opportunities, including a shocking miss by Dimitri Payet, who failed to find the net while goalkeeper Ali Ahamada lay prostrate and helpless on the ground.
Ahamada then made an important save to deny France winger Mathieu Valbuena before Toulouse took a shock lead as Wissam Ben Yedder slotted home a pass from Dane, Martin Braithwaite.
It would have been enough to secure a first win of the season but Mendes headed home a Valbuena free-kick three minutes from time to earn a point.
Even so, Elie Baup's team will need to up their game considerably if they are to gain anything at home to Arsenal in the UEFA Champions League in midweek.
"We had some good periods, especially in the first half, some real quality moves, well co-ordinated, but we didn't turn them into goals," Marseille coach Elie Baup said.
Sochaux dropped to the bottom of the table following a 1-0 defeat at Nantes, who moved up to sixth.
Reims are fifth after a goalless draw at Montpellier while Ajaccio continue to fall -- they are now just one place above the relegation zone - following a 3-2 defeat at home to Evian.
Their Corsica neighbours Bastia drew 1-1 with Guingamp.
