Shanghai SIPG became the second club through to the AFC Champions League knockout stages courtesy of a 1-0 win at Ulsan.
Yohei Toyoda shot wide in the 39th minute and within 60 seconds the Japanese striker inexplicably blazed over from just two metres out when it seemed easier to score with the goalmouth gaping.
The result sees SIPG remain five points clear at the top of Group F with two rounds left in the group stage but Ulsan now find themselves level with Melbourne Victory, who left it late to beat Kawasaki Frontale 1-0 for their first win of the campaign.
Qualification from Group H is still wide open after leaders Kashima Antlers drew 1-1 at home to Sydney FC Tuesday.
It was the J1 League side who initially took the lead three minutes before the half-hour mark, after a awful attempt at a clearance by Joshua Brillante allowed Mu Kanazaki to score with an easy header from point-blank range.
New Zealand worldwide Barbarouses beat Jung Sung-ryong at his near post in the 90th minute to give the hosts a precious three points.
In West Asia, former champions Al Sadd jumped to the top of Group C on goal difference with a 4-0 thrashing of Uzbekistan's Nasaf in Doha.
Matt Simon cancelled out Mu Kanazaki's first-half opener to earn the A-League champions just their second point, although Suwon Bluewings' 2-0 success at Shanghai Shenhua means Group H's top two is nearly finalised.
Abdelkarim Hassan, Baghdad Bounedjah and Jugurtha Hamroun were also on target for the hosts, who are now top of Group C.
Dejan Damjanovic and Choi Sung-kuen were both on target to give the Korean club a four-point buffer to third-placed Shanghai.
Shanghai SIPG is unbeaten on 10 points at the top and guaranteed a place in the knockout stages while Kawasaki, quarter-finalists previous year, are bottom with just one point.
Meanwhile, in Group A, Tractor Sazi and Al Ahli drew 1-1 with Al Jazira and Al Gharafa respectively.
