Arthit Suntornphit put the visitors ahead just before the hour mark when he slotted home from close range but Brazilian striker Lucas rescued J League side Gamba when he struck in injury time.

Gamba had started well as Bare sent a header crashing against the crossbar in the 13th minute before Yasuhito Endo's free kick was palmed away for a corner by goalkeeper Kosin Hathairattanakool six minutes later.

Hathairattanakool then denied Shinichi Terada just before the break to ensure the two sides were level at half time.

But the visitors were ahead in the 58th minute when Ney Fabiano broke down the wing before beating Hroki Mizumoto in the box and unleashing a powerful shot which struck Hideo Hashimoto.

The ball fell perfectly for Arthit who made no mistake from close range.

Gamba piled forward to ensure they did not fall victim as one of the shock defeats of the opening games but were frustrated by the fine form of goalkeeper Hathairattanakool, who denied Lucas just after the hour mark and two Bare shots.

But, with time running out, Gamba finally found the equaliser they were searching for when former FC Tokyo striker Lucas slotted home deep in injury time.
