South Korea sealed their place in the Asian Cup quarter-finals with a 2-1 victory over Bahrain after extra time in Dubai.
Kim Jin-su's header in the second minute of injury time at the end of the game's first extra period was enough to deny Bahrain a famous win over a side ranked 60 places above them in FIFA's global standings.
Mohamed Al Romaihi had cancelled out a goal from Hwang Hee-chan to force the additional 30 minutes at Rashid Stadium, but Kim Jin-su met Lee Yong's cross to settle a tense last-16 encounter.
South Korea dominated the early possession, but it was a stinging strike from Mohamed Marhoon that threatened to break the deadlock in the opening minutes.
