The Flying Eagles had the greater possession and dominated all the areas except the most crucial portion, South Korea’s penalty box, as the Asians wielded a well-knit guard.
Korea did not register a shot attempt until stoppage time in the first half. Nigeria attempted seven shots and handily won the possession battle, with Victor Eletu and Salim Lawal knocking on the Korean door in the opening 45 minutes.
Nigeria continued to dominate the run of play in the second half and they had answers to Korea’s counterattack attempts.
The teams remained goalless after 90 minutes, with Korea unable to put any shot on target.
Korea was able to push through, five minutes into extra time. Captain Lee Seung-won took a corner which was headed in by Choi Seok-Hyun past the helpless goalkeeper Kingsley Aniagboso. It was Korea’s first shot on target in the match.
The two-time FIFA U-20 World Cup first runners-up did try to set up a comeback into the game but Korea’s defence stood solid as they secured a semi-final spot.
