Lille and Monaco kept pace with leaders Paris Saint-Germain, both winning 1-0 in Sunday's Ligue 1 action in France.
Pape N'Diaye Souare scored six minutes from time to keep Lille second in the table four points behind PSG with a win over ten-man Toulouse.
In Sunday's late kick-off, substitute Mounir Obbadi's 70-minute strike kept Claudio Ranieri's Monaco in the chase as they came away with all three points from fellow newly-promoted side Nantes.
Monaco's first win in four games puts them third in the table five points off the pace.
Rene Girard's Lille extended their run to nine games without conceding a goal as Nigerian international goalkeeper Vincent Enyeama has kept his slate clean for 855 minutes of action.
"I don't know if we're going to be able to compete with PSG. For the moment Paris are four points ahead, you can't say that they've pulled ahead," said Girard.
It was a largely unconvincing display from the northerners who struggled to create anything despite playing the final 34 minutes with a numerical advantage following Oscar Trejo's red card.
Enyeama was required to save his side on three occasions from Ben Yedder, Issiaga Sylla and Adrien Regattin. But Souare found space at the back post from Florent Balmont's cross from the right to head home and snatch the three points.
Meanwhile, Saint-Etienne got back to winning ways at Nice despite the absence of their fans. The visitors however let their football do the talking with Mevlut Erding scoring his first goal for Saint-Etienne after 23 minutes, lifting his side to sixth.
It was a fourth straight defeat for Nice, who were hit by a string of injuries, with an error from third goalkeeper Luca Veronese, 22, accounting for the goal.
