Australia's Western Sydney Wanderers beat defending champions Guangzhou Evergrande to reach the East semi-finals of the Asian Champions League where they will take on FC Seoul.
After Western Sydney won the opening match 1-0 in Sydney, Guangzhou edged the Wanderers 2-1 in the return-leg, leaving the teams level 2-2 on aggregate but the Australian side advanced on away goals.
The Wanderers are the first A-League club to reach the Asian competition's semi-finals since Adelaide United in 2008.
In the other quarter-final, goal-keeper Yu Shang-hun made three saves in the shootout as FC Seoul defeated Pohang Steelers 3-0 on penalties.
The teams played 210 minutes without scoring - the first-leg in Pohang and 120 minutes on Wednesday in Seoul.
In the shootout, Yu stopped the first three Pohang shooters, saving captain Hwang Ji-soo's low shot to his right, punching out Kim Jae-sung's attempt by diving to his left, and then diving again to his left on Park Hee-chul's low strike.
Al Ain, winner of the inaugural Champions League tournament in 2003, will face Saudi club Al Hilal in the West semi-finals.
Al Hilal will host the first leg on September 16, with the second leg set for September 30 in the United Arab Emirates.
