The Round of 16 second legs of the 2014 AFC Asian Champions League were completed on Wednesday night.
Eight teams have made it through to the quarter-finals with just one of those coming from behind after a first leg defeat.
That side is A-League runners-up Western Sydney Wanderers who have progressed to the final eight in their first-ever campaign in Asia.
The Wanderers lost 3-1 to Sanfrecce Hiroshima in Japan last week but managed to turn the tide on the J.League outfit by winning 2-0 in Parramatta to go through on away goals. Second-half goals from Shannon Cole and Brendon Santalab saw Tony Popovic's men overcome the visitors and book their spot in the quarters.
Reigning champions Guangzhou Evergrande were beaten 1-0 by Cerezo Osaka in China but were easily through after hammering the Japanese side 5-1 last week, keeping alive their hopes of defending their title.
Ghanaian striker Asamoah Gyan scored twice as UAE club Al-Ain beat league rivals Al-Jazira 2-1 to progress 4-2 on aggregate as Saudi Arabia's Al-Ittihad beat domestic adversaries Al-Shabab 3-1 in Riyadh to win 4-1 on aggregate.
Pohang Steelers kept their noses ahead of K-League opponents Jeonbuk Hyundai to win 3-1 on aggregate following a 1-0 triumph in Pohang as FC Seoul escaped elimination at the hands of Kawasaki Frontale despite losing 2-1 at home. The Korean giants managed to go through on away goals after a 4-4 aggregate.
Qatar's Al-Sadd are into the elite eight thanks to their 2-2 draw with Iran's Foolad which gave them an away goal victory while Al-Hilal gave Saudi Arabia another representative when they beat Uzbekistan's Bunyodkor 3-0 in Riyadh to win 4-0 on aggregate.
The dates for the quarter-finals will be August 19 and 26 for the West Asia zone and August 20 and 27 for the East Asia zone.
