South Korea upset Australia 1-0 at the Asian Cup to top the Group A standings and secure a potentially easier path to the final while leaving the host nation facing a treacherous route.
Striker Lee Jeong-hyeop scored a perfectly-executed goal in the first half to give his team a surprise lead then the Koreans held on against a wave of Australian attacks to clinch the victory.
The win meant South Korea finished at the top of the Group A standings with three wins and will play either Uzbekistan or Saudi Arabia in the quarter-finals.
As Group A runners-up, Australia will play the Group B winners China with the defending champions Japan lurking as a possible semi-finalist.
In the other Group A match, being played at the same time in Newcastle, Oman beat Kuwait 1-0 to finish third in the group, courtesy of a 69th minute header from Abdul Aziz Al-Maqbal.
Neither team had the chance to advance after losing their first two matches.
