Vietnam booked their place in the semi-finals of the 2026 ASEAN Cup on August 7 by finishing atop Group A after a dominant 3–1 performance against Cambodia at My Dinh Stadium in Hanoi. The convincing victory, coupled with an unbeaten group-stage campaign, leaves Vietnamese coach Kim Sang-sik's side in a commanding position ahead of the knockout stages, while leaving regional observers to assess how well Vietnam's form translates against stronger opposition.
From the opening minutes, Vietnam's intent was unmistakable as they sought to impose their game on Cambodia through sustained possession and aggressive play down the flanks. The home crowd's presence appeared to energise the Vietnamese players, who showed tactical discipline in building from the back and creating numerical advantages in attacking areas. Cambodia, however, refused to be overawed by their opponents' initial ascendancy, and they fashioned a genuine opportunity to capitalize on their counter-attacking approach in the 14th minute when Samuel Bong found himself presented with a clear one-on-one chance against goalkeeper Patrik Le Giang, only to squander the opening.
Vietnam's breakthrough arrived just four minutes later through Nguyen Dinh Bac, whose penetrating run through Cambodia's midfield allowed him to advance into the penalty box and deliver a precise low finish past keeper Koy Salim. The goal appeared to settle the home side's nerves, and they subsequently maintained control of the tempo and territory. Cambodia's response was to retreat into a deeper defensive shape, prioritising solidity at the expense of pressing Vietnam's ball-carriers, a pragmatic but ultimately restrictive approach that limited their attacking opportunities as the first half concluded with Vietnam holding a slender 1–0 advantage.
Cambodia's defensive approach persisted into the second half, yet it proved ineffective in preventing Vietnam from accumulating chances. The hosts continued to dominate possession and create threatening positions, suggesting that a second goal appeared inevitable. However, tournament football frequently delivers unexpected turns, and in the 71st minute, Cambodia produced a moment of genuine quality that restored parity when Iago Bento latched onto a lengthy aerial delivery, accelerated past Pham Xuan Manh, and coolly finished beyond Le Giang to level the match at 1–1.
The equaliser injected fresh momentum into Cambodia's display and raised questions about Vietnam's ability to withstand external pressure in competitive fixtures. Nevertheless, Vietnam's superior depth of resources and tactical flexibility eventually proved decisive. In the 84th minute, Nguyen Xuan Son engineered space to shoot, forcing Cambodia's Im Vakhim to desperately clear the ball, only to inadvertently deflect it into his own net and restore Vietnam's lead at 2–1. The own goal reflected Cambodia's increasing desperation and the mounting pressure Vietnam continued to exert.
Vietnam sealed the result conclusively in the 90th minute when Dinh Bac added his second goal, executing a clinical finish during a swift counter-attack to establish a final scoreline of 3–1. The brace capped an impressive individual performance from Bac and underscored Vietnam's clinical edge in front of goal. Coach Kim Sang-sik's team accumulated ten points across four group matches comprising three victories and one draw, establishing a commanding first-place finish that reflects their superiority throughout the preliminary phase.
Singapore secured qualification for the semi-finals as runners-up in Group A following their 1–1 stalemate with Indonesia, whose elimination removes one of Southeast Asia's traditional footballing powers from contention. The outcome ensures that Vietnam and Singapore will contest opposite semi-final berths, with the second semi-final pairing to be determined by Group B's concluding fixtures scheduled for August 8. Thailand currently lead Group B with nine points accumulated from three consecutive victories, positioning themselves as strong contenders for the tournament.
Malaysia occupy second place in Group B with six points and remain very much in contention to progress alongside Thailand, though their pathway depends on results against the Philippines in their final group encounter. Myanmar also possess six points but trail Malaysia on head-to-head record, maintaining mathematical qualification possibilities but facing mounting pressure. The Group B finale will therefore resolve critical questions about which teams complete the semi-final lineup, with implications for Southeast Asian football's competitive hierarchy and the tournament's eventual champion.
Vietnam's group-stage dominance reflects their status as tournament hosts and previous continental champions, yet the format's completion will provide a clearer picture of their standing relative to Thailand, Malaysia, Singapore and other regional opponents. The semi-finals are likely to feature far tighter contests, with Vietnam required to sustain their impressive form against elevated opposition. For Malaysian followers and observers across Southeast Asia, the tournament's knockout stages promise compelling encounters that will test each nation's tactical sophistication, mental resilience and technical capabilities under intensified pressure.
