Ulsan showed their intent when Matias Lacava drove through the Buriram midfield from deep inside his own half before releasing Yago Cariello behind the defence, but Neil Etheridge was off his line quickly to ensure the forward’s attempt was blocked.

Suphanat forced Jo Hyeon-woo to take action at the other end moments later but there was nothing the Korea Republic international could do to keep out the Bissoli strike that gave Buriram the lead.

The Brazilian was gifted possession deep inside the Ulsan half as Jung Woo-young slipped and the striker was only too happy to surge forward to slam the ball past the diving Jo from the edge of the area.

Jo ensured the home side did not double their lead five minutes later when Bissoli again took aim, the Ulsan goalkeeper this time managing to tip the ball away for a corner at full stretch to his left.

That save was to pay off in the first minute of added time as Ulsan pulled level. Darijan Bojanic’s pass through the Buriram defence found Jang unmarked and the 22-year-old forward had the time to slide a low shot past Etheridge.

Suphanat wasted a gilt-edged opportunity three minutes into the second half when he sent a weak header, when unmarked, into Jo’s hands and six minutes later he was ruled offside after curling a perfectly measured strike around the goalkeeper.

Etheridge kept out Park Min-seo’s attempt from his right as Ulsan sought the winner needed to stay alive while a sprawling Jo pushed Martin Boakye’s effort wide for a corner as the action started to swing from end to end.

Suphanat was denied at close range with five minutes remaining by substitute goalkeeper Moon Jung-in, on after Jo suffered a blow to the face, but he made no mistake eight minutes later, sliding in at the far post to convert Dion Cools’ cross from the right.
