Vietnamese Football and the Ceiling of Belief: From Park Hang-seo to Kim Sang-sik, a Journey Not Yet Closed

On the night of January 5, 2026, in a small cafe in Busan, I sat alone in front of an old television. Vietnam were playing the second leg of the ASEAN Championship final against Thailand, and somewhere in the first half, Nguyen Xuan Son collapsed after a collision. The whole cafe went quiet. Not one person in there was Vietnamese, nobody was supporting either team, but everyone understood that something had just broken. I sat motionless, holding a cup of coffee that had gone cold, thinking about the moment football always needs in order to become immortal: a pain that is shared.

Vietnam won anyway. A 5-3 aggregate score, a Southeast Asian title, and a naturalised striker breaking his leg on the finest night of his life. But I do not want to write about the trophy. I want to write about the ceiling above it - the ceiling Vietnamese football has been reaching for and falling from for nearly a decade.

ONE CAFE, TWO KOREANS, AND A SENSE OF SELF

I am English, I have lived in South Korea for a long time, and I write about football for a market that is not my own. That makes me look at Vietnamese football through a strange lens: through its Korean teachers.

In October 2026, the Vietnam Football Federation appointed Park Hang-seo. He had been an assistant to Guus Hiddink at the 2026 World Cup, a quiet man who dressed plainly and brought with him a football that was not beautiful. Four months later, in January 2026, Vietnam's under-23 side reached the final of the AFC U-23 Championship in Changzhou, China, and lost 1-2 to Uzbekistan in a match played in falling snow. An entire nation poured into the streets. I watched from Busan, and I remember thinking: they are not crying because they lost. They are crying because, for the first time, they saw themselves in a place far too large for their everyday existence.

Then, in December 2026, Vietnam won the AFF Suzuki Cup, beating Malaysia 3-2 on aggregate. In January 2026 they reached the Asian Cup quarter-finals, losing only 0-1 to Japan. In February 2026, on Lunar New Year, they beat China 3-1 at My Dinh - their first victory over China in the final round of World Cup qualifying. Park Hang-seo left in January 2026, after a final defeat to Thailand.

His successor was Philippe Troussier, a Frenchman with a glittering CV and a philosophy that was its exact opposite. Troussier wanted Vietnam to control the ball, to play on the front foot, to shed the shell of counter-attacking defence. The result was a run of dark days. In March 2026, after two defeats to Indonesia - 0-1 away and 0-3 at home in My Dinh - Troussier was sacked. Vietnam also ended their 2026 World Cup qualifying campaign at the second round, while Indonesia advanced to the third.

Then, in May 2026, another Korean arrived: Kim Sang-sik. And seven months later, Vietnam were champions of the ASEAN Championship.

I recount this sequence not to summarise history. I recount it to show something few people say out loud: for nearly a decade, Vietnamese football has been a project designed by Koreans. Park laid the foundation with discipline and pain. Troussier tried to demolish it and brought the house down. Kim came to rebuild. Three men, three philosophies, but only one nation in between.

THE TACTICAL ANCHOR: WHEN VIETNAM PLAY THE FOOTBALL OF THE WEAKER SIDE

The first thing to say about Vietnam's tactics is this: they have never played the football of the stronger side. And that is not a weakness - it is an identity.

Under Park Hang-seo, Vietnam operated a deep defensive block, usually a 5-4-1 out of possession, shifting into a 3-5-2 in attack. They did not try to keep the ball. They gave it to the opponent, held their lines with extreme discipline, and waited. When they won the ball back, they transitioned in three or four passes, straight into the flanks. It was a football designed for the underdog, and Park executed it almost perfectly at regional level.

But here is the point I want to stress: Vietnam's counter-attacking football is effective in direct proportion to the gap in quality between them and their opponent - it is strong when they are underestimated, and weaker as they are rated more highly. In Southeast Asia, Vietnam are usually the stronger team, forced to hold the ball, and their system then exposes gaps. In Asia, they are the weaker team, allowed to defend, and they become extraordinarily difficult - as in the 0-1 Asian Cup defeat to Japan in 2026, a match decided by a single individual moment.

Troussier understood this in reverse. He believed that to go far, Vietnam had to learn to keep the ball. It was a belief that was beautiful in theory and disastrous in practice, because it demanded something Vietnamese football did not yet have: players trained to make decisions under high pressure in tight spaces. The result was matches in which Vietnam both lost the ball more often and exposed space behind their defence. The three goals conceded to Indonesia at My Dinh were an indictment.

Kim Sang-sik did the opposite of Troussier: he returned to pragmatism. He did not try to turn Vietnam into a possession side. He accepted that Vietnam win by defending well, transitioning quickly, and exploiting moments. And at the 2026 ASEAN Championship, that brought the trophy.

Here I want to offer an observation I have tracked: throughout the 2026 tournament, Vietnam were not the side with the most possession. They were the side that scored from transitions and set pieces. That was no coincidence. It was a deliberate choice.

A DRY DATA TABLE: THE NUMBERS OF A FOOTBALL NATION LOOKING FOR A PLACE

I have always believed that emotion must be built on a table of data. Otherwise it is just crying. So let me put a few numbers on the table, without decoration, without miracles.

First, the regional stage. Vietnam have been one of the most decorated teams in Southeast Asia over the past decade: AFF Cup winners in 2026, finalists in 2026, winners in 2026, plus SEA Games gold medals. No team in the region can match that record over the same period.

Second, the continental stage. In 2026 World Cup qualifying, Vietnam reached the third round for the first time. In 2026 World Cup qualifying, they stopped at the second round, behind Iraq and Indonesia. This is a measurable step backwards, and it happened at the same time as Indonesia accelerated their naturalisation programme.

Third, the structure of the domestic game. V.League 1 is a competition in which most clubs operate below a safe financial threshold, dependent on a handful of big sponsors and on wealthy patrons whose commitment is not always sustainable. This is a landscape in which a club can win the title and dissolve a few years later. That financial instability is one reason young players lack a stable environment in which to develop.

Fourth, youth development. The Hoang Anh Gia Lai JMG Academy, founded in 2026, produced a golden generation - Nguyen Cong Phuong, Nguyen Tuan Anh, Luong Xuan Truong, Nguyen Van Toan, Vu Van Thanh. That is a real achievement. But here is the part rarely discussed: the HAGL academy model produced talent, but the league system could not keep it. Those young players were scattered, sold, loaned, and their peak years passed inside a competition lacking depth.

Fifth, transfers. The 2026 ASEAN Championship was a tournament in which naturalisation reigned. Nguyen Xuan Son, born in Brazil, was the top scorer and the best player of the tournament. Naturalisation gave Vietnam the striker they had lacked for years. But it also raises a question I find more worrying than reassuring: if regional success comes from a player not developed in Vietnam, then where is the domestic development system?

I leave those five numbers standing alone, without poetry, without music. They are the skeleton. The rest is flesh, and the flesh must be grown by the reader.

FOOTBALL AS A RITUAL OF BELONGING

There is one word I return to again and again when writing about football: belonging. Vietnamese football is the story of a nation learning to belong to a stage larger than itself.

Vietnamese people do not follow the national team the way one follows a sport. They follow it the way one follows a part of their identity being shaped. When the team wins, the streets of Hanoi and Saigon spill out like a red river, and inside that river, every person finds a place to stand. I have never seen that anywhere else, including England - where football is a religion, but a religion with numbered seats.

And I understand that, in a way. I am an Englishman writing about football in South Korea, and all my life I have been a man standing outside his own stand. I know the feeling of someone looking for a home in a place they do not belong to. I look at Vietnamese football and see a nation doing the opposite: turning a pitch into a home.

Some stars only burn brightest where they are loved, not where the lights are brightest. Nguyen Quang Hai is one such star. He shines brilliantly in the national shirt, on nights when an entire country faces a single point. But his club career, despite moves abroad, has never reached the stature his talent deserves. In Vietnam, a player is not valued most where he plays every week. He is valued most where he is loved.

That is a beautiful paradox and also a trap. Because a football nation whose value is decided by the emotions of its audience, rather than by the quality of its league, will always struggle once it steps beyond the borders of its own emotion.

THE "PATRON" CULTURE AND THE GOVERNANCE PROBLEM

You cannot talk about Vietnamese football without talking about the men behind it. Here, football is run by a network of wealthy, committed businessmen - men the press still call "bau". They are the ones who poured money into clubs, into academies, and sometimes into dreams.

This cuts both ways. The good side is that Vietnamese football has academies that would never have existed without private money. The other side is that a football nation dependent on the goodwill of individuals can never build a sustainable system. When a patron tires, a club can vanish. When a patron changes his mind, an entire generation of young players can be left behind.

Football governance is a dry profession that few write about, because it produces no goals. But it is the thing that decides whether a football nation can pass its own ceiling. In Vietnam, the governing bodies have achieved a great deal - organising competitions, developing youth teams, connecting with continental football. But a large gap remains: the transparency of the transfer system, the rights of players, and the independence of refereeing. These are not Vietnam's problems alone - they are the problems of nearly all Southeast Asian football. But as long as they persist, the ceiling stands.

THE NATURALISATION RACE AND THE QUESTION OF IDENTITY

While Vietnam celebrated their title, another race was being run in silence. Indonesia, under coach Shin Tae-yong, naturalised a wave of players of European descent and turned their national team into a side transformed in physique and speed. They advanced to the third round of 2026 World Cup qualifying, while Vietnam stopped.

Vietnam have entered this race too, with Nguyen Xuan Son the clearest example. And I must be honest: naturalisation is not a sin. Modern football is a global market, and every nation has the right to use it. But there is a difference between using naturalisation to fill a gap and using it to hide a gap.

If a naturalised striker helps Vietnam win Southeast Asia, that is a success. If, after he leaves, Vietnam still have no striker of that level, that is a failure of the development system. And here is what I believe: a football nation cannot buy an identity. It can only build one. Naturalisation is a tool, not a foundation.

THE CONTRARIAN ANGLE: THE 2026 TITLE DOES NOT PROVE WHAT PEOPLE THINK IT PROVES

This is where I must say something that may cost me goodwill.

The victory at the 2026 ASEAN Championship is being presented as a revival. Kim Sang-sik arrived, rebuilt the team, and delivered the trophy. The headlines overflow with praise. And there is indeed something to praise - a wounded team found itself again.

But I am not sure it proves anything larger than a regional win. A Southeast Asian title does not erase the fact that Vietnam failed to get past the second round of 2026 World Cup qualifying, while Indonesia - a side rated below them only a few years ago - managed it. That is the crux: Vietnamese football is progressing on the stage where it was already good, and standing still on the stage where it needs to progress.

One could argue that the 2026 ASEAN Championship was a tournament Vietnam benefited from when several major rivals lacked their strongest squads, that the title was built on one naturalised player and a handful of moments. I am not sure I am right, but I believe it must be said: a football nation that judges itself by the emotion of a single festival night will never see its own ceiling.

There is a line I wrote years ago, on a night I could not sleep: "I write against the wind, but my heart is never against football." I say this not to diminish Vietnam's victory. I say it to wake a question that has fallen asleep: if the belief of the audience is the fuel, then what goal is that fuel burning for?

THE CEILING: WHY VIETNAM HAVE NOT YET PASSED THEMSELVES

If I had to name Vietnam's ceiling, I would name it with three words.

The first is the league. A football nation only advances through the quality of its domestic competition. V.League 1 needs more than generous patrons and crowded derbies. It needs sustainable professionalism, facilities, sports medicine, and a transparent transfer system. Without those, every talent is drained before the age of twenty-five.

The second is the fixture calendar. This is what I believe most firmly across my entire writing career: fixture density is the single greatest cause of injury, and no medical staff can save a team playing two matches a week. I have watched hundreds of players break down because of the calendar, and I see Vietnamese football heading down exactly that path: a dense domestic season, regional tournaments, national-team windows, and very little genuine rest. Nguyen Xuan Son's injury in the 2026 final was a direct collision - I do not attribute it to the calendar, because that would be dishonest - but it is a reminder that Vietnamese players play inside a system that does not put their safety first.

The third is youth development. I have written many times about a mechanism I call the "satellite club system": big clubs circumventing domestic-training rules by turning smaller clubs into nurseries for their own talent. In Vietnam, this mechanism exists in a different form but with the same essence: young talent becomes an asset circulated between clubs, rather than nurtured in a stable environment. The HAGL golden generation was a miracle. But a football nation cannot live on miracles. It must live on systems.

On this point, I want to be honest about my own humility. I am an Englishman writing about Asian football from an apartment in Busan, and I do not live the days of a V.League player. I may be wrong about the severity of each problem. But the ceiling I see clearly, and it is not in the talent. Vietnam has talent. The ceiling is in the system.

VIETNAMESE FOOTBALL AND THE IMMORTALITY OF A NATION

I once cried because of football, even though it was not my country's football. It was the night of June 27, 2026, when South Korea beat Germany 2-0 at the World Cup. I sat in a silent cafe in Busan, and I cried for the immortality of football. But in that same period, I was also following Vietnam, and I realised that the two stories were alike in one respect: both were nations trying to tell the world that they exist.

Football is the land of immortality, but immortality does not mean winning forever. Immortality means being reborn after every fall. Vietnam fell in 2026 World Cup qualifying, and they were reborn at the 2026 ASEAN Championship. It is a ritual I have seen hundreds of times in my life: death, life, and death again.

What I want to say to Vietnamese readers, if anyone has read this far, is this: your pain is not a weakness. But it is also not a solution. Tears on a keyboard are as salty as tears on a pitch, and I have shed enough of them to know that crying does not make a football nation grow. What makes it grow is cold mornings on the training ground, transparent contracts, properly trained sports doctors, and a league that people come to watch not only out of love, but out of curiosity.

TAKEAWAY: A VERIFIABLE PREDICTION

I will finish with a judgement you can hold me to in the coming years.

If Vietnamese football continues to invest in regional tournaments and naturalised stars without reforming the structure of V.League 1 and its youth development, then by 2030 World Cup qualifying they will again stop at the second or third round - and that will no longer be treated as a failure, but as normal. That is how a ceiling becomes a wall.

But if they do the opposite - if they turn the next golden generation into one nourished by a system rather than by a miracle - then Vietnamese football will have a genuine chance not only to burn brightest where it is loved, but to shine where the lights are brightest.

I am not certain. I only dare to write. And I write against the wind, but my heart is never against football.
