Bangkok took the lead in the 11th minute after Muhsen Alghassani threaded the ball through for Ilias Alhaft, who rode the challenge from Mohammad Abualnadi then saw his first attempt blocked by Kalamulah Al Hafiz but made no mistake with the rebound.

Selangor had little opportunity to regain their composure before the Thai side struck again, Jakkapan Praisuwan with a teasing cross from the right flank four minutes later that was nodded home by Alghassani.

The end-to-end game then saw Selangor pull a goal back in the 23rd minute when Quentin Cheng got into space on the right and delivered a low cross that was swept home by Chrigor Moraes.

Bangkok, however, only needed a minute to restore their two-goal advantage as Alhaft’s shot took a heavy deflection off Kevin Deeromram and looped over Kalamulah to settle in the net.

Matters got worse for the Malaysian side in the 39th minute when they went down to 10 men after Harith Haiqal committed a professional foul on Seia Kunori as he was running through on goal.

After the interval, Selangor had the opportunity to reduce the deficit immediately when Cheng nodded the ball across for a simple tap-in for Moraes but the forward’s heavy touch sent the ball wide when it looked easier to score.

Despite being at a numerical disadvantage, Selangor kept going and had a chance to pull within a goal of Bangkok but Faisal Halim’s decision to opt for another touch instead of taking a first-time shot from Zack Clough’s cross allowed Patiwat Khammai the time to close him down.

Selangor’s persistence was rewarded in the 73rd minute when Aliff Izwan tucked home a rebound seconds after coming on in place of Deeromram but in the end, it was nothing more than a consolation as Philipe Maia’s 84th minute header sealed the points for Bangkok.
