Kim Min-Woo bagged a brace to help South Korea to a 3-0 win over Paraguay in the U-20 World Cup on Monday, which saw them qualify for the quarter-finals.

Before putting his name to the score sheet, Min-Woo had a hand in the opener five minutes from the hour mark when his drive was diverted by Joel Silva into the path of Kim Bo-Kyung who tucked home with ease.

Min-Woo ensure South Korea's superiority five minutes later with a second goal after he smashed past the keeper, after latching onto a quickly-taken free kick to get in the area.

Shortly after, Paraguay's Rodrigo Burgos was sent off for two bookable offences to widen his team's woes.

Twenty minutes from time, Min-Woo headed the third to wrap up the precious victory for the Koreans.

South Korea now will face the winners of the playoff between Ghana and South Africa on Friday.
