Jurgen Klinsmann overcame Roberto Mancini as South Korea advanced to the quarter-finals of the Asian Cup on penalties after a dramatic draw against Saudi Arabia.

South Korea won 4-2 in the shoot-out after the round-of-16 match had ended 1-1 after extra time.

Defeat will be particularly hard for Mancini to take as Saudi Arabia led 1-0 deep into stoppage time at Education City Stadium through Abdullah Radif's 46th-minute strike.

Cho Gue-sung levelled the game in the 99th minute to send it into an additional period, then South Korea goalkeeper Jo Hyeon-woo was the hero in the shoot-out when saving penalties from Sami Al Naji and Abdulrahman Ghareeb.

Hwang Hee-chan converted the winner from the spot to send his country through to the last eight and a match against Australia on Saturday (AEDT | NZDT).

Uzbekistan are also into the quarter-finals after beating Thailand 2-1, setting up a clash with hosts and defending champions Qatar.

Azizbek Turgunboev put Uzbekistan ahead in the 37th minute, controlling Diyor Kholmatov's diagonal pass on his chest and volleying low past Patiwat Khammai.

Thailand equalised through Supachok Sarachat's curling effort from outside the box 13 minutes after half-time, but it took just seven more minutes for Uzbekistan to regain the lead with what proved to be the decisive goal from Abbosbek Fayzullayev, who struck from distance to beat Khammai.
