Bae Ji-won and the Crack Behind the Trophy: How Vietnam Lost to Thailand

In the 10th minute at Si Jalak Harupat Stadium in Bandung, Sarach Yooyen received the ball about 25 metres from the Vietnam goal. No red-shirted player stepped out in time. The shot flew into the top corner, and the match was effectively shaped from that instant. A second goal followed later, sealing a 0-2 scoreline and stripping Vietnam of top spot in Group B of the ASEAN Cup 2026.

I sat for a long time after the final whistle. What troubled me was not the scoreline, but the manner of the defeat.

Thirty-four days earlier, this very team had drawn 2-2 with Thailand in the ASEAN Cup final and lifted the trophy. The distance between the summit and the ground turned out to be shorter than expected. Data I compiled shows this was Thailand's first win over Vietnam after three defeats and one draw. That number says a great deal about the psychological cycle on both sides, but it is not the whole story.

The real story lies in how Thailand won, and how Vietnam lost.

Coach Bae Ji-won, who has managed clubs in the K-League and spent time working in Vietnam, offered blunt assessments after the match. He said Vietnam "revealed many problems." That is a diplomatic phrasing. Reading closely what he analysed, I see it is not the problem of one match, but the problem of an entire tactical system.

In my profession, the first lesson never comes from a signed contract, but from a rumour no one has confirmed. I learned that to understand a match, you must read the gaps between the answers. And the match in Bandung had plenty of such gaps.

Territorial dominance and the trap set in advance

Basic statistics show Vietnam had more possession. The red shirts pressed Thailand back into their own half, mounted continuous attacks, and created the feeling that an equaliser was only a matter of time. But that feeling never became reality.

Thailand deliberately dropped deep. They did not need the ball. They needed space, and they waited for Vietnam to create that space themselves.

This is the key point many overlook. Holding more possession is not an advantage when the opponent does not want to contest the ball. With Vietnam's current squad, holding the ball only exposes the limits of their ability to break through a crowded defensive block. Bae Ji-won pointed this out, and from my observation, he is right.

Look at how Thailand organised. Their central midfield trio played with extreme discipline, sealing the half-spaces behind Vietnam's strikers. Their two full-backs sat deep, resisted the urge to push forward, and willingly sacrificed attacking potential to ensure safety. The result was that Vietnam held the ball but had no one to pass to.

I have watched many matches involving Southeast Asian teams, and I recognised a familiar pattern. When opponents deploy a low block, Southeast Asian sides often fall into an identical state of impasse. They circulate the ball sideways, push it wide, then cross into the box. There is no surprise, no change of tempo. The opposing defence simply stands in position and waits.

That is exactly what happened in Bandung.

The moments that should have been the solution

The interesting thing is that Vietnam were not entirely stuck. Bae Ji-won pointed to two specific moments that could have become solutions.

In the 37th minute, Nguyen Tai Loc put the ball in the net but the goal was disallowed for offside. In the 58th minute, Nguyen Hoang Duc made a notable penetrating run into Thailand's box. Those were moments when Vietnam broke the defensive block by playing the ball through the opponent's midfield, rather than circulating it in front.

The problem is that those moments arrived randomly. They were not the product of a well-drilled attacking pattern, but of isolated individual efforts. The team has the tools to break a low block, but lacks the process to use those tools consistently.

This is the point I want to emphasise. In modern football, the difference between a good team and a great team lies in reproducibility. Great teams can create chances in the same way, over and over, against any opponent. Good teams wait for individual moments of brilliance.

Vietnam in this match were a good team, not a great one.

Bae Ji-won recommended improving ball circulation speed, sustaining pressure, and diversifying attacking options. He also suggested bringing on Pham Gia Hung to exploit aerial ability. These are technical suggestions, but they touch on a deeper issue: whether the Vietnam national team has enough personnel to execute those options at all.

When the injury storm is no longer an excuse

Four key players were absent or played below peak condition: Nguyen Thanh Chung, Nguyen Quang Hai, Nguyen Xuan Son, and Nguyen Hoang Duc. According to the information I have, the cause was playing continuously over a short period.

I do not want to turn this into an excuse. But I also do not want to ignore it. Four key players injured from overload is not a matter of chance. It is a workload-management problem, and it is systemic.

In my career, I have witnessed similar crises. In 2026, when the pandemic left stadiums empty, I acted as a bridge between a supporters' group and the board of a K-League 2 club on the brink of bankruptcy. Across six online meetings, I learned one thing: fitness crises and financial crises share the same root, namely a lack of preparation for worst-case scenarios.

Vietnam won the ASEAN Cup. But that victory seemed to mask a reality: this team lacks squad depth. When four key players fail to reach peak condition, there is no equivalent replacement. Bae Ji-won calls it a personnel problem. I call it a development-cycle problem.

Thailand are different. Their midfield trio are not only technically gifted but battle-hardened. They know how to manage a match when leading. They know how to slow the tempo, commit tactical fouls at the right moments, and wait for counter-attacking chances. That is the kind of experience Vietnam, at this moment, does not yet have.

Looking from the other side of the touchline

In my profession, there is a principle I always try to follow: list each side's motivations before writing, cross-check them, and let the answers reveal their own limits. So I cannot view this match only from Vietnam's side.

Thailand won, but not convincingly in the eyes of their own fans. Thai experts and supporters have criticised coach Anthony Hudson for his pragmatic style. A Thai expert, Be Bangkapong, said that looking only at the final result is enough.

This is an intriguing paradox. Thai football is undergoing a debate about identity: between a tradition of beautiful play and a results-first pragmatism. This debate is not confined to Thailand. It is unfolding across Southeast Asia.

Hudson chose the pragmatic path. He deployed Chanathip Songkrasin as a false nine, a relay station rather than a genuine centre-forward. This arrangement did not work perfectly as intended, but it was enough to create a threat that forced Vietnam's centre-backs higher, opening space behind them.

Thailand won through discipline, not creativity. And in elite football, discipline sometimes matters more than creativity.

Contrarian angle: What the scoreline does not say

I have a habit of writing a "Contrarian Angle" column, where I challenge my own conclusions. On this match, I must say this: concluding that Vietnam are in crisis is a hasty conclusion.

One defeat does not define an era. Vietnam remain the reigning ASEAN Cup champions. They still have coach Kim Sang-sik, who took the team to the summit barely over a month ago. Four injured players are a genuine mitigating factor, not an excuse.

But if I had to point to one blind spot in the official narrative, it is this: Vietnam's problem is not losing one match, but having no tactical answer to a specific type of opponent. Thailand produced a blueprint for beating Vietnam. That blueprint will be copied by other teams.

When another Asian side faces Vietnam, they will study the Bandung match. They will see that if they play a low block, score first, and wait, they have a chance. That is the biggest strategic risk this defeat leaves behind.

Kim Sang-sik's substitutions were also questioned by Bae Ji-won. He argued that not bringing on Pham Gia Hung to exploit aerial ability was a waste. I do not have enough information to judge whether that was tactical rigidity or a lack of trust in backup personnel. But I know one thing: in football, a good agent does not sell players; they sell a future priced in trust. The same applies to a coach. When he does not trust his backup options, he limits his own capability.

The next domino

The question is not whether Vietnam will advance from the group. The question is whether they will learn the lesson of Bandung before the knockout stage begins.

Bae Ji-won offered specific suggestions. Ball circulation speed. Sustained pressure. Diversified attacking options. These are fixable technical issues, but they require time and a shift in coaching mindset.

The personnel problem is harder. Four players injured from overload is a warning about how Vietnamese football manages its calendar. If the V.League continues to schedule densely around national-team windows, this situation will recur. This is no longer a national-team problem alone; it is a systemic one.

In closed meeting rooms, people talk about price. In the corridors outside, they talk about the fear of being left behind. I believe that at the Vietnam Football Federation right now, some people are worried about exactly that. Not the fear of losing one match, but the fear of being left behind in Southeast Asian football's tactical arms race.

Thailand have changed. They accept playing ugly to win. Other teams in the region are learning. And if Vietnam do not find an answer to the low-block problem, defeats like Bandung will no longer be the exception.

I once wrote before I listened. Now, I listen to the gaps between the answers. And in the silence after the Bandung defeat, I hear an unanswered question: is the ASEAN Cup trophy a destination, or merely a stop on a much longer road?
