The Thai champions had lost 3-0 at Urawa Red Diamonds on Matchday One while Jeonbuk came into the game on the back of a fine 3-1 victory at home to Beijing FC.

But Supachok’s second-half strike resulted in a reversal of fortune for both sides and put Buriram back on course to compete for a place in the Round of 16 for the second year in a row.

Jeonbuk looked the more impressive side in the opening stages and Lee Dong-gook’s volley had to be deflected wide in the 14th minute.

Two minutes later, Siwarak Tedsungnoen did well to hold onto Ricardo Lopes’ awkward bouncing shot from distance.

Looking to bounce back from last week’s 3-1 defeat to Jeonbuk Hyundai Motors, the home side took immediate control of the game and it was Zhang Xizhe that had the first real chance on goal when he fired low and hard from the edge of the area, forcing a good save from Shusaku Nishikawa after just 10 minutes.

Roger Schmidt’s team should’ve taken the lead eight minutes later when Cedric Bakambu was played in one-on-one with Nishikawa. Having done the hard bit by rounding the Urawa custodian, he inexplicably pulled his shot wide from an acute angle to let the visitors off the hook.

Daegu, playing their first ever home game in the AFC Champions League, could not have picked a more illustrious opponent than the two-time winners and, after both had won their opening fixtures, it was forward Kim who stole the show against the Chinese side.

His inch-perfect cross from the left allowed Brazilian Edgar to volley home midway through the first half, before he found Cesinha, who played in Edgar for Daegu’s second as the interval approached.

There was a scrappy opening to the game and neither side was able to gain the upper hand in the first 20 minutes.

There was finally a chance for Ulsan in the 21st minute but Kim Su-an failed to get enough power on his header, allowing Yan Junling to save comfortably.

The hosts almost gifted SIPG the opening goal when Oscar intercepted a loose crossfield pass from Dave Bulthuis. The Brazilian advanced on goal and his shot from 25 yards was pushed wide by Oh Seung-hoon.

On a chilly night in Kawasaki, the home side were looking for their first win in the AFC Champions League since 2017 and they had a great chance to take an early lead, but new Brazilian striker Leandro Damiao sliced his effort just wide after 12 minutes.

JDT’s Safawi Rasid forced an early save from Lee Bum-soo as his curling shot threatened to sneak in at the far post.

Diogo Luis Santo must have impressed the watching Ronaldo with an audacious attempt in the 24th minute. After a flowing move, the ball made its way to S. Kunanlan on the right and his cross was met with an overhead kick that flew just over.
