Despite scoring their first in the ninth minute, France could have already had a couple of goals by that time.

Eugénie Le Sommer finally capitalised on her side's intense attacking pressure to score the first goal of the tournament. 

Griedge Mbock Bathy then had an emphatic volleyed goal ruled out for offside by the video assistant referee, but 6ft 2in centre-back Wendie Renard showed her expertise in the air by heading home in the 35th and 45th minutes.

The match had already been won by the half-time whistle but France continued to command the game in the second-half. 

Amandine Henry made the result certain when she curled the ball round South Korea's goalkeeper from just outside the penalty box in the 85th minute.
