Coach Bae Ji-won Points Out Vietnam's Tactical Flaws After Thailand Defeat

In the match at Group B of the FIFA ASEAN Cup 2026 at Si Jalak Harupat stadium, Bandung, Indonesia, Vietnam lost to Thailand 0-2. This result not only cost Vietnam top spot in the group but raised concerns about their ability to break down deep-defending opponents.

Match Context

Just 34 days after winning the ASEAN Cup 2026 with a victory over Thailand in the final, Vietnam under coach Kim Sang-sik entered the rematch as defending champions. Experts and fans expected Kim's squad to continue asserting their strength. However, Thailand proved they had learned valuable lessons from their previous defeat.

Thailand under coach Anthony Hudson showed a completely different face. They proactively ceded possession, organized a tight low block, and waited for counter-attacking opportunities. Sarach Yooyen's opening goal in the 10th minute from a strike outside the box forced Vietnam to push forward in search of an equalizer, creating favourable conditions for the opponent.

Tactical Analysis: The Problem Lies in Imposing Play

Football analyst Bae Ji-won, who has years of experience following Southeast Asian football, made sharp observations about this match. He believes Vietnam did not reach peak form and exposed many problems in their ability to impose their game on opponents.

The key point in Bae Ji-won's analysis is that Vietnam controlled possession but could not convert that advantage into clear chances. Thailand proactively dropped deep, organized a multi-layered defensive structure, and let Vietnam hold the ball in non-threatening areas. Thailand's central midfield trio and full-backs excelled at closing spaces.

Vietnam's problem was not ball retention but how they used the ball. Currently, Vietnam possesses many players capable of quick transitions and attacking spaces behind the defensive line. However, when facing a deep block, those qualities can no longer be effective.

Bae Ji-won also pointed to specific moments where Vietnam could have created breakthroughs. Nguyen Tai Loc's offside-called run in the 37th minute and Nguyen Hoang Duc's penetrating run in the 58th minute were typical examples. This shows Vietnam has individuals capable of creating danger against a packed defence, but those moments lack repeatability and are not organized systematically.

Squad Quality Differences

One issue Bae Ji-won emphasized was squad quality and substitution capability. Thailand possesses a deep squad with experienced midfielders. Their central midfield trio played with high discipline, ready to drop deep to support defence when needed.

Meanwhile, Vietnam struggled to find replacement options of equivalent quality. This partly stems from many key players having fitness issues. Thanh Chung, Quang Hai, Xuan Son, and Hoang Duc all struggled with injuries due to a congested schedule in a short period. Losing important players in key positions significantly reduced coach Kim Sang-sik's ability to change the game.

Bae Ji-won questioned some of Kim Sang-sik's substitution decisions. He argued that not bringing Pham Gia Hung on to create an aerial threat in the final minutes was regrettable. Gia Hung may not be a complete player, but in a context requiring chaos in front of goal, his presence could have made a difference.

Contrarian View: The Problem Is More Than One Defeat

There is another way to look at this defeat that analysts rarely mention. Vietnam conceding early in the 10th minute completely changed the match dynamics. Thailand with a lead could comfortably implement the counter-attacking game they wanted. This is a favourable scenario for a team committed to pragmatic play.

In reality, the inability to impose play when trailing is not a new problem for Vietnamese football. In the past, when facing Southeast Asian opponents organized in tight defence, Vietnam often struggled similarly. What is different this time is that Thailand proactively built a game plan based on deep understanding of Vietnam's weaknesses.

Thailand under coach Anthony Hudson is showing a shift in philosophy. They no longer pursue attractive attacking football with intricate combinations but instead pragmatism and efficiency. The presence of players like Chanathip Songkrasin as a relay station created a different threat. Although Thailand did not regularly use Chanathip as a false nine, his presence forced Vietnam's defence to push up to track him, creating spaces behind.

Notably, even when winning, Thailand still faces criticism from experts and fans about their style. A Thai expert bluntly commented that just looking at the final result is enough. This view reflects a division existing in Thai football between those who want beautiful play and those who prioritize results.

The tension between these two views will continue to be a long-running story during Hudson's tenure. When results are favourable, criticism will temporarily quiet down. But if performances decline, pressure about style will quickly return.

Impact on Vietnamese Football

This defeat and Bae Ji-won's analysis may have deeper implications for Vietnamese football. The issue of squad depth and rotation capability is not just a national team story. It reflects systematic limitations of the V.League in developing backup players of equivalent quality.

The congested schedule of ASEAN Cup 2026 posed significant challenges for fitness management. Four key Vietnam players struggling with injuries from playing continuously in a short period is a warning bell about match load management. If this problem is not addressed, Vietnam will continue to face disadvantages in important matches.

From a tactical perspective, this defeat urgently requires developing a more diverse attacking approach. Vietnam needs to solve the problem of imposing play against deep-defending opponents, otherwise other teams will adopt Thailand's formula against them.

Specific solutions include developing automatic positional rotations, diversifying set-piece situations, and seeking alternative striker combinations. Combining an aerially strong striker with a mobile forward could create different options against a packed defence.

Regarding personnel, over-reliance on injury-prone key players raises questions about rotation strategy. Balancing maintaining the first team's strength and creating opportunities for backup players to develop is a difficult equation for coach Kim Sang-sik.

Pressure and Expectations

Vietnamese public opinion is in a state of high alert after this defeat. The story of the team revealing many problems is gradually becoming a hot topic. However, a fair view of the context of this loss is necessary.

This was a match where Vietnam faced many unfavourable factors: a congested schedule after the championship, injuries to key players, and an opponent in the process of shifting their playing philosophy. Drawing systemic conclusions from a single defeat may be an overestimation of the situation's severity.

More important is how Vietnam responds after this defeat. Can coach Kim Sang-sik adjust tactics to solve the imposing play problem? Can players recover physically and mentally to be ready for upcoming matches? Can the coaching staff find new personnel options to strengthen squad depth?

The defeat to Thailand is a challenge but also an opportunity for Vietnam to re-examine their limitations. Bae Ji-won's analysis, though potentially uncomfortable, provides a valuable perspective on areas needing improvement.

Signals from Within

Looking back at this match, the most notable aspect is not the scoreline but how Vietnam handled the situation of being behind. The team's inability to find solutions against an organized defence shows the absence of systematic breakthrough plays.

Vietnam's upcoming matches at ASEAN Cup 2026 will be opportunities to answer whether this defeat is an accident or a sign of a deeper problem. Vietnamese fans will follow closely to see if Kim Sang-sik's squad can learn from this loss and return stronger.

The heartbeat never lies in the ball, but in the people. The defeat to Thailand is not just a story about a match or a scoreline. It is a story about people trying to find ways to adapt to new challenges, about a football nation trying to overcome its own limitations. And in any story, what matters is how we respond to difficulties, not the difficulties themselves.
