Jonathan David's early goal was enough to help second-place Lille secure a 1-0 win at Rennes and stay level on points with Ligue 1 leaders Paris Saint-Germain.
The Canada forward pounced in the 15th minute after goalkeeper Romain Salin failed to properly clear a corner, and the ball fell to him to sweep into the left side of the net.
After a slow start to his Lille career, the 21-year-old David now has four league goals.
The youngster made a sharp run behind the Rennes defence midway through the first half and was awarded a penalty after being fouled by defender Nayef Aguerd.
But referee Eric Wattellier reversed the decision after a video replay showed that David was fractionally offside when making his move, and rescinded the yellow card shown to Aguerd.
The home side threatened little after the break and it was a comfortable win for Lille, who trail defending champions PSG only on goal difference after 21 matches.
Both clubs are two points ahead of third-place Lyon, who won 5-0 at local rivals Saint-Etienne.
Tino Kadewere and Marcelo scored twice, while Memphis Depay created three goals.
Saint-Etienne coach Claude Puel had to field an inexperienced side because several players were unable to play after contracting coronavirus.
Saint-Etienne striker Denis Bouanga scored at the wrong end in the 81st minute, with his own goal from Depay's free kick ending the scoring.
Puel's side is languishing in 16th place.
Elsewhere, Hwang Ui-jo made it three goals in two games for Bordeaux with an early brace in a 2-1 home win against Angers.
Former France coach Raymond Domenech's stint in charge of Nantes is proving difficult, as his team lost 2-0 at mid-table Metz.
