Lee Dong-gook scored the first two goals to set up South Korea's 4-2 win over Uzbekistan in Saturday's friendly game as both teams prepare for World Cup qualifiers on Wednesday.
Former English Premier League striker Lee put the hosts in command at Jeonju World Cup Stadium and Kim Chi-woo netted twice after the break to give coach Choi Kang-hee a win in his first game in charge.
With Korea leading 3-0, Ibrahim Rahimov and Stanislav Andreev scored for Uzbekistan but Kim's late goal ended any hope of securing a draw.
South Korea are preparing for a vital qualifier against Kuwait, with their chances of reaching the next round still in the balance. Uzbekistan will face Japan, with both teams already through to the third round.
