The game against Timor Leste at a neutral site in Thailand kicks off the journey to retain the crown for Kim Sang Sik's men. Going up against the underdog of Group A, Vietnam's target extends beyond securing three points; it's about achieving a resounding win, improving their goal difference, showcasing their prowess, and conserving their squad for the upcoming challenges.
Reaching the summit is tough; maintaining the number one spot is tougher. That's the test awaiting Vietnam from the opening moments of the ASEAN Cup 2026. Though Timor Leste might not be a formidable rival, they serve as the initial gauge of the mettle, readiness, and aspirations of Kim Sang Sik's squad.
Examining the comparative strength, it's difficult to see any parity. Vietnam boasts overwhelming resources, the deepest roster in Southeast Asia, and a meticulously planned buildup for the competition.
A two-week training camp in South Korea, followed by three straight wins over local sides, and a final rehearsal with a 4-0 thrashing of Myanmar in Thai Nguyen, provided an ideal prelude. Vietnam has won all four recent friendlies, netting 14 goals while allowing only four. Crucially, the squad has kept a two-year unbeaten run under Kim Sang Sik, underscoring their consistency in both performance and mentality.
What gives supporters the greatest confidence at this moment is not merely the outcomes, but the manner in which the team finds the net. The Vietnamese forward line is in high spirits, boasting a variety of methods to penetrate the opposition's goal.
Xuan Son provides power and a bulldozing presence inside the box. Dinh Bac has grown in maturity, displaying confidence and pace. Hoang Hen causes chaos with his clever off-the-ball runs, while Quang Hai and Hoang Duc orchestrate the tempo. Even full-backs like Xuan Manh contribute in attack. With so many players capable of scoring, Vietnam has become far more difficult to anticipate.

Vietnam will target a comprehensive victory, a clean sheet, and no injuries to their key players. Goal difference may prove critical in Group A, which also features strong sides like Singapore and Indonesia. A lopsided win over Timor Leste would hand Vietnam an early edge and ease the pressure in the upcoming difficult encounters.
Timor Leste reached the group stage by beating Brunei in the playoffs, yet that does little to narrow the vast chasm in quality. Pedro Alves's side is still heavily dependent on players plying their trade in lower divisions in Australia and Portugal.
Their approach, centered on long balls, wide play, and counting on Joao Pedro's solo efforts, remains flawed. The defensive setup of Timor Leste is disjointed, frequently exposing spaces during transitions. Even Coach Pedro acknowledged the immense disparity and sees the clash with Vietnam as a chance to gain experience.
Nevertheless, this does not give Vietnam the license to be overconfident. In the 2024 ASEAN Cup, Timor Leste gave Malaysia a scare, losing 3-2 only after leading. Lower-ranked teams always give their all against championship favorites. If Vietnam starts the game lacking concentration or rushing against a compact defense, they could face real trouble.
The encouraging aspect is that Vietnam currently possesses multiple ways to break through deep-lying defenses. Their win over Myanmar demonstrated a more varied attacking approach, including central combinations, flank exploitation, and set-piece routines.
The game at Chonburi Stadium is also being held in rather advantageous circumstances, as Timor Leste lacks a certified home stadium. Consequently, the crowd factor is negligible. What remains is solely up to Vietnam to showcase their champion's quality.
To venture into the big stage, Vietnamese football cannot settle for tight victories against inferior sides. A top-tier team must assert its dominance at the opportune moment, convert advantages into decisive edges, and transform the opening game into a declaration of intent for the whole competition.
