BG Pathum United suffered a narrow 1-0 home defeat to Pohang Steelers in their AFC Champions League 2 group stage match on September 18, 2025. A single goal separated the sides in a tense encounter where the Korean visitors' efficiency in front of goal proved decisive. The match's only moment of real quality came in the first half when Pohang scored from a well-rehearsed set-piece routine. BG Pathum United pushed forward in search of an equalizer in the second half and created several half-chances, but they were unable to find a way past a resolute Pohang defense and goalkeeper. The result was a disappointing start to the continental campaign for the Thai side, who were left to rue their missed opportunities.
