It was the visitors who started the better with Tainan City nearly catching Madura napping in the 12th minute when Mohamed Sakkouh teed up Matheus Porto at the top of the box, but the Brazilian midfielder’s shot was straight at keeper Miswar Saputra.

The Chinese Taipei side squandered another chance seven minutes later when Toninho outmuscled his marker on the right flank and slipped a neat pass to Porto, who miscued his effort.

Madura finally found their rhythm in the 20th minute when Taufik Hidayat collected Miljan Skrbic’s pass from inside the box, with his effort testing Tainan custodian Pan Wen Chieh.

Iran Junior almost put the Indonesian side ahead two minutes later after he pounced on a poor clearance from Kim Sungkyum, while Lulinha failed to find the target from inside the area in the 27th minute.

The Indonesian side’s persistence finally bore fruit in the 38th minute after Brayan Angulo strode down the left before cutting the ball back to Junior, who struck a low shot into the bottom right corner. 

Tainan City struggled to find momentum and were caught again in the 59th minute after Junior’s defence splitting pass created space for Lulinha, who held off his marker before striking the ball into the bottom left corner.

The Chinese Taipei side came under pressure again in the 74th minute when they were caught on a counter-attack, leading to Junior teeing-up substitute Youssef Ezzejjari, whose curling effort from above the box sailed just wide of the right post.

Tainan City threw everything they had at Madura but their forward approach left them exposed and failure to deal with Lulinha’s cross from the left led to Andi Irfan bundling the ball into the back of the net from close range in the 84th minute as they confirmed their semi-final ticket in style.
