South Korea maintained their unbeaten start under former Portugal coach Paulo Bento on Tuesday as they thrashed Uzbekistan 4-0 in Brisbane.
Hector Cuper's side offered little threat to the Koreans, who will be among the favourites to win the Asian Cup when they travel to the United Arab Emirates for the continental championship in January.
Qatar-based midfielder Nam Tae-hee put Bento's team in front after nine minutes when his bouncing volley beat Uzbek goalkeeper Ignatiy Nesterov.
Fifteen minutes later Hwang Ui-jo doubled the lead when he smashed the ball in from a tight angle after Uzbekistan failed to clear a corner.
Moon Seon-min added a third in the 70th minute with a left-footed strike from outside the area and Suk Hyun-jun completed the rout eight minutes from time.
The Koreans have now played six games since Bento succeeded World Cup coach Shin Tae-yong, winning three and drawing three.
