Selangor got off to a fast start with Nooa Laine timing his run into the box to perfection in the fourth minute to reach Alvin Fortes’ cross, only to see his point-blank header saved by Kittiphong Phoothawchuek. 

The home side were not to be denied a minute later when Yohandry Orozco’s shot took a deflection and fell kindly for Quentin Cheng to sweep home past Kittiphong.

While Muangthong regained their composure and had captain Picha Autra directing traffic at the heart of midfield, they found little joy against Selangor’s back three of Safuwan Baharudin, Harith Haiqal and Umarbek Eshmurodov. 

Selangor had the opportunity to widen their lead going into the break when Ahmad Zikri made a forceful run in the 37th minute from the left before laying the ball to Orozco in the middle of the box, however, the Venezuelan sent his attempt just wide.

The Thai side started the second half the better of the two sides and pulled level eight minutes in when Harith inadvertently headed Muangthong’s corner back across his own goal, allowing Felicio Forbes to bundle in from close range.

The frame of the goal twice stood between Selangor and a second goal, Ronnie Fernandez struck his effort against the upright in the 65th minute followed by Fortes against the opposite post two minutes later.

However, it was Muangthong who once again showed their set-piece prowess in the 76th minute to take the lead, Poramet Arjvilai’s initial header was blocked by Zikri but the forward slammed the rebound home.

Selangor came within a whisker of drawing level with seven minutes left to play but luck was not on their side as the post denied them again, this time through Safuwan’s strike as they suffered a second consecutive defeat.
