A quartet emerged victorious on Tuesday and Wednesday to complete the quarter-final line-up of the 2012 AFC Champions League, with Adelaide United, Bunyodkor, Guangzhou Evergrande and Ulsan Hyundai progressing to join the already-qualified Al Ittihad, Al Hilal, Al Ahli and Sepahan in the last eight.

It proved to be a fiercely-contested matchday, with all four games won by a one-goal margin. The Japanese rounded off their campaign in miserable fashion, though, with all three teams going out, while Australia, Korea Republic and Uzbekistan each boast a team into the next knockout phase.

The match
Ulsan
Hyundai 3-2 Kashiwa Reysol
Cheered on by a raucous home crowd, hosts Ulsan Hyundai pinned Kashiwa Reysol in their own third during the opening half, wreaking havoc with marauding runs and spectacular shots. However, their poor finishing, lack of luck, and a series of superb saves by visiting goalkeeper Takanori Sugeno all combined to deny the hosts as they went into break with nothing to show for their efforts.

The home team piled on the pressure after the restart and their efforts finally paid dividends on 54 minutes when Kim Shin-Wook opened the scoring. Their lead, however, lasted just 13 minutes as Leandro Domingues drew level with a header to put the game on a knife-edge. With so much at stake, Ulsan restored their advantage when Lee Ho's cross was turned home by Naoya Kondo. Lee Keun-Ho would put the game beyond doubt with a superb volley two minutes from time, leaving Junya Tanaka's last-minute effort nothing more than a consolation.

The surprise
Seongnam
 Ilhwa 0-1 Bunyodkor

Having set a new Asian record by becoming the first team to progress beyond the group stage in all five attempts, Bunyodkor continued their amazing run as they edged hosts Seongnam Ilhwa by a single goal. The continental campaign has so seen the Uzbeks get past a trio of former champions en route to the last eight. The Central Asians first sealed the second qualifying spot at the expense of Gamba Osaka and Pohang Steelers during the group stage, before upsetting Ilhwa to book their third appearance in the quarter-finals.  

The Koreans were dominant throughout the opening half, with Yoon Bit-Garam and Hevertinho both coming close to opening the scoring. However, it was the visitors who went in front eight minutes after the interval when Hayrulla Karimov converted a penalty earned by Kamoliddin Murzoev. The remainder of the game belonged to Bunyodkor's international goalkeeper Ignatiy Nesterov, who repeatedly frustrated the hosts’ attack as his side defended their slender lead.

The other attractions
Like Bunyodkor, Adelaide United secured a 1-0 defeat of Nagoya Grampus largely courtesy of some brilliant goalkeeping by Eugene Galekovic. The keeper first pushed away Josh Kennedy's powerful downward header and after Jon McKain bundled home to put his side ahead before the break, the Reds captain once again came to the team's rescue by smothering out a headed chance from Mu Kanazaki 15 minutes from time as the 2008 runners-up progressed to the last eight for the second time.

Marcello Lippi got his first Asian campaign off to a dream start as Guangzhou Evergrande edged FC Tokyo at home 1-0. Despite playing away, the Japanese were the first to attack, with Lucas stinging goalkeeper Yang Jun’s hands with a powerful drive early on. Having weathered the early pressure, the hosts gradually clawed themselves into the contention and they scored the match-winning goal on half-an-hour when Cho Won-Hee's pass across the goalmouth was bundled home by Cleo.

The player
Muriqui was always at the centre of Guangzhou’s attacking threat. He had a hand in the side's only goal as he sent Cho clear in to the area, before twice going close to doubling the lead in the second half. His efforts were all the more impressive considering that he had only just returned from injury.

The stat
1
- Al Ittihad became the only one of five former champions to survive the competition so far, while Guangzhou emerge the sole representatives of the nine-tournament debutants into the last eight.

What they said
"We left our rivals with few chances and little space so we played a good game as I expected. Next we have three months to prepare for the quarter-finals and I hope the players can make the best of this period to sharpen their form and get fit for the next showdown," Marcello Lippi, Guangzhou Evergrande coach
