Son Heung-min's South Korea sent Saudi Arabia crashing out of the Asian Cup 4-2 on penalties on Tuesday to set up a quarter-final with Australia, after a nail-biting game ended 1-1.
Substitute Abdullah Radif struck just after coming on at half-time for Saudi Arabia, but Cho Gue-sung equalised deep in injury time to force extra-time, and from there the game went to penalties.
