Nigeria boosted its hopes of reaching the knockout stages of the Women's World Cup with a 2-0 win over South Korea.
An own goal from Kim Do-yeon, given after a VAR check, and Asisat Oshoala's strike in Grenoble got the Super Falcons off the mark in the tournament.
They now face host France in their final game in Group A, while South Korea, who remains without a point but still has an outside chance of qualification, faces Norway.
Both sides entered the game in search of a response to defeats in their opening group games.
It was South Korea, beaten 4-0 by France in the tournament's curtain-raiser, who started the more purposefully with Lee Geum-min testing Nigeria goalkeeper Chiamaka Nnadozie with a curling effort before Lee Mi-na drove narrowly wide.

However, its opponents took control against the run of play courtesy of a defensive error when Kim inadvertently volleyed beyond her onrushing goalkeeper and into her own goal.
Referee Anastasia Pustovoytova eventually gave the goal after a lengthy VAR check to determine whether Nigeria forward Desire Oparanozie had handled the ball before it crossed the line.
Oparanozie headed narrowly over in the 50th minute, while South Korea were denied a goal for offside nine minutes later.
Nnadozie could count herself fortunate when she palmed a cross straight to Lee, who converted only for the offside flag to go up.
Barcelona's Oshoala sealed the victory with 15 minutes left when she latched onto Chidinma Okeke's excellent pass to squeeze home from a tight angle.
