Guilherme Bissoli almost put Buriram in front in the seventh minute, the Brazilian stretching to meet Kingsley Schindler’s inviting cross from the right but the forward’s toe poke bounced agonisingly wide of Yan Junling’s right post with the Port goalkeeper beaten.

Eight minutes later, however, Supachai converted. Robert Zulj picked up possession 25 yards from goal and the Austrian slipped his pass into the area for Supachai to beat Yan in the race to the ball, lifting his effort over the China PR international’s attempt to block.

Neil Etheridge denied Shanghai Port an equaliser in the 24th minute when the Philippines international parried Wang Shenghcao’s header to safety after the defender emerged through a crowd of players to nod Oscar Melendo’s free kick towards goal.

Shanghai Port probed for a way through before the interval with Matheus Vital among those frustrated as the Chinese Super League side were unable to prize open the home defence.

Those frustrations continued after the interval with substitute Lyu Wenjun’s weak header trundling wide on the hour mark and five minutes later the visitors saw the deficit doubled through an error by Yan.

Theerathon Bunmathan delivered a corner from the right towards the far post and, with Yan grasping at thin air, Goran Causic headed back across the face of goal and Good gleefully tapped in from millimetres out.

Good headed over the bar as another corner caused concern in the Port defence with 11 minutes remaining while Port should have claimed a consolation at least, but Li Shenglong headed his 87th minute effort wide despite being unmarked eight yards from goal.
