London - New Tottenham Hotspur signing Son Heung-min demonstrated his finishing abilities with a hat-trick as South Korea walloped lowly Laos 8-0 in their World Cup qualifier in Hwaseong on Thursday.
Son, who joined the English club for a reported €30 million from Bayer Leverkusen last week, struck in the 17th minute to make it 2-0 after slotting in a cut back cross.
A powerful strike from an acute angle by the 23-year-old made it 5-0 in the 74th minute and he completed his first international hat-trick a minute from time with a tidy run and finish.
The win was the Koreans second from two games in Group G ahead of Tuesday's away match in Lebanon. Kuwait and Myanmar are the two other teams in the group.
Only the group winners in the pool, which also serves as the qualifiers for the 2019 Asian Cup, are guaranteed a spot in the next round of matches in the continent's long road to Russia 2018.
