Vietnam vs Singapore: Coach Kim Sang Sik's Strategic Calculations

Coach Kim Sang Sik's strategy introduces a new dynamic, turning the Vietnam team into a formidable and versatile squad. While still in its early stages, it has sparked intriguing possibilities for future games.

The emphatic 7-0 victory over Timor Leste in the opening match of the ASEAN Cup 2026 not only secured a significant advantage in points and goal difference. More notably, the performance in this tournament unveiled a completely new dimension in the offensive organization of the Vietnam team under Coach Kim Sang Sik. The decision not to rush into forming a fixed starting lineup reflects a long-term strategy, prioritizing versatility and adaptability among players against any opponent.

Since taking charge of the Vietnam team, Coach Kim Sang Sik has consistently adhered to the 3-4-3 formation. In this system, decisive attacks often come from the wings, where full-backs push high to execute overlaps or crosses for strikers to finish.

While this style has yielded many successes in the past, it has also become a predictable pattern that strong opponents like Thailand or Indonesia can study and neutralize. Recognizing this risk, the South Korean coach has quietly prepared a tactical shift.

Starting from the friendly match against Myanmar and effectively implemented in the encounter with Timor Leste, the Vietnam team has reduced the frequency of monotonous crosses. Instead, the team has actively increased small-group combinations in the central area. Direct attacks through the opponent's central corridor have appeared frequently, with high speed and precision.

Looking back at the win over Timor Leste, what stands out is not just the number of goals but the way they were orchestrated. Although each goal had its own scenario, the common thread was that most decisive finishes came from intelligent runs into the gaps between the opposing center-backs.

This change demonstrates the improving ability of Vietnamese players to play short, fast, and direct football. Moving away from over-reliance on wide attacks makes the offensive rhythm much more unpredictable. When gaps are spotted in the middle, attacking players immediately break through directly instead of shifting the ball out wide as before.

Although Timor Leste is not a strong enough test to fully gauge the team's strength, the manner of victory is what experts appreciate. Coach Kim Sang Sik is clearly honing a complete "Plan B" in preparation for tougher matches in the knockout stage.

In a demanding tournament like the ASEAN Cup, rivals such as Thailand, Indonesia, or Malaysia have surely memorized Vietnam's wide-play patterns. Therefore, proactively adding the ability to attack through the middle with one-twos or through passes is the key for Coach Kim Sang Sik to refresh the lineup, creating a diverse and unpredictable playing style.

This tactical variation has room to thrive as the Vietnam team now possesses midfielders capable of creating high-impact moments, such as Quang Hai, Hoang Duc, and Hoang Hen. Additionally, the presence of naturalized striker Xuan Son provides an ideal focal point for direct attacks, thanks to his excellent hold-up play and ability to lay off the ball. In a tournament lasting over a month, the champion team needs not only attractive football but also multiple ways to approach the goal.

In summary, in terms of operation, the current Vietnam team demonstrates remarkable flexibility with a high-intensity pressing game and rapid transitions. Although major challenges from Thailand, Indonesia, or Singapore still lie ahead, with a stable core and a strong desire to prove themselves, Coach Kim Sang Sik's squad is brimming with confidence as they aim to conquer the Southeast Asian championship.
