Video replay was the MVP for France on Monday.
A contentious VAR decision helped the host nation earn a 1-0 win over Nigeria and secure the top spot in Group A.
After sending an errant penalty off the outside of the post with just over 10 minutes to go in Rennes, French defender Wendie Renard was allowed to retake the spot-kick when teenage goalkeeper Chiamaka Nnadozie was adjudged by VAR to have jumped off her line early.
Replays showed she was mere inches off the line when Renard struck the ball.
Given a reprieve, the imposing center-back made no mistake the second time around, ensuring that France finished up the group stage with three wins from as many matches. It's the first time it has ever won all three group games at the World Cup.
Nigeria, sitting on three points, will wait to see if that's enough to secure a knockout spot as one of the best third-placed sides. The South Koreans are going home after losing all three matches.
