Kotaro Omori scored a late winner as Gamba Osaka beat Buriram 2-1 in their Group F AFC Champions League match which took place at the New I-Mobile Stadium on Tuesday.
Theeraton Bunmatan scored the only goal for Buriram when the two sides drew 1-1 in Japan and was on the scoreboard again in the ninth minute when he headed home from a corner kick, after a period of concerted pressure.
Buriram's Brazilian striker Diogo had the opportunity to put the hosts even further in front after 15 minutes when he was found unmarked in the Gamba box, but could only fire his shot straight at Masaaki Higashiguchi in the visitors' goal.
Gamba continued to search for the equaliser, though, and five minutes from the half-time whistle industry when Brazilian forward Lins managed to get his shot away – albeit against the run of play – and leveled matters.
Hiroyuki Abe found Shu Kurata on the left flank and the midfielder cut the ball back to Lins, who made no mistake from close range to beat Siwarak Tedsungnoen with his shot.
Buriram continued to show the more attacking intent in the second half as Diogo was once again denied by Higashiguchi from close range.
The hosts thought they scored the winner five minutes from full time when Theerathon thought he got his second of the night, before being flagged for offside.
Two minutes later, Buriram were made to pay the ultimate price for their slackness in front of goal when Koki Yonekura cushioned a pass into the path of substitute Omori, who struck a sweetly-timed volley past Siwarak.
After four matches, Buriram is on seven points in second position in Group F.
Gamba is lying on the bottom of the table on four points but with every chance of still qualifying for the next round following Tuesday's result.
