The Rain at Thong Nhat Has Gone, But Vietnam's Winter Just Burned: The 2026 AFF Cup Triumph and What We Haven't Said Yet

The rain at Thong Nhat in 2026 washed away the fear of young writers. I wrote about Cong Phuong in that rain like a father crying for his child. Seven years later, I no longer sat in the stands of the home stadium to hear the rain beat on the tin roof. I sat in front of a screen, more than 1,800 kilometers from Bangkok, and heard the screams of millions of Vietnamese people burst out on the night of the second leg final of the 2026 AFF Mitsubishi Electric Cup. On January 5, 2026, at Rajamangala Stadium, Vietnam defeated Thailand 3-2 in a match that no statistical figure could fully capture. But I am a football poet, and I know that after every great match, there are always things we haven't said. The context of this championship is not simple. Vietnam entered the tournament with a South Korean coach, Kim Sang-sik, who had less than six months to rebuild a team that had suffered a disappointing 2026 Asian Cup with three straight losses under Philippe Troussier. Fans were accustomed to watching the team play possession-based football, but Kim Sang-sik brought a different philosophy: proactive defense, fast transitions, and maximizing the physical strength of players. This change made many people skeptical. I remember one evening in late November, I wrote in my notebook: "Hanoi's winter came early this year, and the whole country is waiting to see if Kim's fire is warm enough." The turning-point decision was recalling Nguyễn Xuân Son – a naturalized Brazilian-born player – into the squad. Son, born Rafaelson Bezerra Fernandes, had a brilliant 2026 V.League season with 31 goals for Thép Xanh Nam Định, breaking the record for goals in a single season. But calling up a naturalized player is always a sensitive topic in Vietnam, where the concept of "Vietnamese blood" still holds value. Kim Sang-sik staked his career on this decision. And that bet changed history. But let's talk about the final, because the 3-2 win at Rajamangala was not just a match. It was a symphony of moments. In the 8th minute, Nguyễn Hoàng Đức – a player I've followed since his days at Viettel – opened the scoring with a long-range shot from outside the box. The ball flew hard, low, and tore through the Thai defense. I remember writing while watching: "That shot didn't just go through the defense, it went through Vietnam's 20-year obsession with Thailand." But Thailand, the team that had won the AFF Cup two consecutive times, was not easy to subdue. They equalized 1-1 in the 28th minute and took a 2-1 lead in the 63rd minute. In the stands, 40,000 Thai fans cheered. In the living rooms of millions of Vietnamese families, the atmosphere sank. And then Nguyễn Xuân Son appeared. In the 82nd minute, from a fast counterattack, Son received the ball in the middle, shielded it cleverly against the Thai defender, then unleashed a precise left-foot shot into the far corner. 2-2. Rajamangala Stadium fell silent. Four minutes later, Son headed in from a cross by Phạm Tuấn Hải, sealing the 3-2 scoreline. A brace by a naturalized player in the final on Thai soil. I couldn't sit still. I stood up, walked around the room, and wrote in my notebook: "People say football is a sport for the young, but I watch it to see how fast I used to run." The aggregate score over two legs was 5-3 in Vietnam's favor. And that was Vietnam's third Southeast Asian championship, after 2026 and 2026. But this championship carries a different meaning. It didn't come from beautiful possession football. It came from pragmatism, from accepting pain to wait for the moment of explosion. In the first leg final at Việt Trì, Phú Thọ, where snow has never fallen but the cold pierces the bones, Vietnam won 2-1 in a match where Thailand controlled 58% of possession. They accepted giving up ground, giving up the ball, and punished the opponent with deadly counterattacks. Based on my 33 years of experience following Southeast Asian football, I can say that this victory was not a coincidence. It is the result of a radical tactical transformation. Kim Sang-sik built a defensive block with two steel center-backs, Bùi Hoàng Việt Anh and Nguyễn Thanh Chung, and two full-backs with superior speed and stamina, Vũ Văn Thanh and Hồ Tấn Tài. He used Nguyễn Hoàng Đức as a "metronome" – the one who regulates the rhythm of the match – and Nguyễn Quang Hải as a free artist behind Son. But the most important thing, and this is what I want to emphasize, is how Kim Sang-sik managed the team's intensity. In a tournament lasting nearly a month with 7 matches, keeping the team at its best physical condition for the final is a difficult puzzle. He rotated the squad intelligently, giving key players rest in the last group-stage match against Myanmar, and used squad depth effectively. Data from the tournament shows Vietnam averaged only 48.2% possession across 7 matches, but they had the highest xG (expected goals) in the tournament with 14.7. They created 87 shots, 31 on target, and scored 21 goals – the most in the tournament. But the most impressive figure was 5.2 km/h – the average sprint distance per match of Nguyễn Xuân Son. He ran less than many other players, but every sprint was decisive. This brings me to a view I've held for years: distance covered and sprint counts are often packaged as effort metrics, but ineffective running also produces pretty numbers. Son didn't run much, but he ran at the right moments. In modern football, precision of timing matters more than abundance of energy. But now, let me talk about what few dare to mention in this jubilant atmosphere. This championship, though great, has exposed an uncomfortable truth: Vietnam still relies too heavily on a 27-year-old naturalized player who suffered a broken leg right in the final and had to leave the pitch on a stretcher. Nguyễn Xuân Son scored 7 goals in the tournament, breaking the record of his predecessors. But when he left the pitch in the 90th minute, his face contorted in pain, I suddenly realized that a whole generation of Vietnamese strikers still cannot replace him. Công Phượng is 29 and no longer at his peak. Phạm Tuấn Hải, though excellent, is more of a winger than a pure number 9. And the question arises: are we too dependent on short-term solutions? This is my counter-intuitive angle: this victory could create a dangerous complacency. I remember 2026, when Vietnam first won the AFF Cup, the whole country celebrated as if we had conquered the world. But 16 years later, we only had one more championship in 2026. Meanwhile, Thailand – the team we just beat – has won 4 more times. Consistency, not explosive moments, is the measure of a great football nation. Kim Sang-sik has done a wonderful job, but will he stay? His contract expires in March 2026, and offers from the K-League have already appeared. If he leaves, we start from zero again. Let's look at the numbers from a financial perspective. This victory brings the Vietnam Football Federation (VFF) about $4.5 million in prize money from AFF and sponsors. But the cost of naturalizing Nguyễn Xuân Son, including the 5-year residency wait and legal procedures, is a long-term investment. The bigger question is: can we produce our own "Xuân Son" from our academies? The PVF Academy, HAGL Academy, and other training centers have invested millions of dollars, but the best products they've produced in the past decade are still Nguyễn Quang Hải and Nguyễn Hoàng Đức – talented players but not natural-born strikers. The gap at the center-forward position is a systemic problem, not anyone's fault. But I don't want to end this article with a gloomy warning. Football, as I've written many times, lies in the silence between two touches of the ball, where the hearts of spectators score goals on their own. On the night of January 5, 2026, millions of Vietnamese people scored together. I saw posts on social media – a father hugging his son and crying uncontrollably, a group of students dancing on Nguyễn Huệ walking street, an 80-year-old grandmother in Hải Phòng calling her granddaughter to ask "did we win, child?". In that moment, I understood that this championship doesn't belong to Nguyễn Xuân Son, doesn't belong to Kim Sang-sik, doesn't belong to the VFF. It belongs to the people who waited 7 years since the last time they could celebrate. I was at Thong Nhat Stadium in 2026, where the rain washed away the fear of young writers. I sat in the stands of Kazan in 2026, witnessing Mbappé teach physics a lesson about speed. And I sat in front of a screen on the night of January 5, 2026, hearing the screams of an entire nation burst out. Every generation has a moment to remember. For my generation, it was 2026. For the younger generation, it was 2026. For children born after 2026, tonight is the beginning of their most beautiful memory. And when Nguyễn Xuân Son left the pitch on a stretcher, his face in pain but still smiling, I remembered what I wrote in my old notebook in the quiet winter: "Opening an old notebook in the quiet winter, I see hope – measured by heartbeat." The rain at Thong Nhat in 2026 washed away the fear of young writers. The night at Rajamangala in 2026 washed away the fear of an entire generation of fans. But the biggest question remains: what will we do with this victory? Will we build a truly effective youth development system, or will we continue to rely on stopgap solutions? Will we keep Kim Sang-sik, or will we change coaches mid-stream again? I don't have the answer. But I know that, as I wrote in an old poem: "I'm too old to chase the ball, but young enough to chase the highlights on screen." And tonight, I am young again. Let me say one last thing about tactics, because that's what I know best. In the second leg final, Kim Sang-sik used a 3-4-2-1 formation without the ball, switching to 4-3-3 with it. This created incredible flexibility. When Thailand had possession, Vietnam's 4-man midfield compacted, creating a wall in front of the box. When they had the ball, the wing-backs pushed high, and Nguyễn Quang Hải had space to drift into the half-spaces. But the most interesting thing was how they used Nguyễn Xuân Son as a decoy – a sacrificing player. Son would often drag two Thai center-backs out of position, creating space for Hoàng Đức or Quang Hải to burst through. It was from such a movement that Hoàng Đức's opening goal was created. This is smart football, not beautiful football. And in finals, smart always beats beautiful. But I cannot end without mentioning a special person: Đỗ Duy Mạnh. The 28-year-old center-back played all 7 matches of the tournament with outstanding form. He averaged 8.2 clearances per match, the highest in the tournament, and more importantly, he was the spiritual leader of the defense. In the second leg final, when Thailand pushed forward looking for a goal, it was Duy Mạnh who organized the defensive line to hold firm. He didn't score, didn't assist, but he is the reason Vietnam conceded only 6 goals in 7 matches. In a modern football world full of attacking stars, Duy Mạnh is a reminder that silent warriors are the foundation of every championship. And then, when the final whistle blew, I saw Kim Sang-sik run onto the pitch, embracing every player. This 48-year-old South Korean man, who was heavily criticized after the 0-2 loss to India in a friendly in October, had become a hero. He did what many thought impossible: brought Vietnam back to the top of Southeast Asia in just 6 months. But I wonder: are we worshipping a savior we will soon forget? The history of Vietnamese football is full of coaches who were heroes before becoming villains. Remember Park Hang-seo, who took Vietnam to the 2026 U23 Asian Cup final and the 2026 AFF Cup semi-final, but was criticized for negative defensive football in his final years. A coach's career is an endless loop. I want to dedicate these final lines to an image I will never forget. When Nguyễn Xuân Son was carried off on a stretcher in the 90+3rd minute, the Thai players, who had just lost the match, applauded. That was a moment that transcended tactics, transcended the scoreline, transcended everything. Football, in that moment, was no longer a match. It was a symphony of respect. And I remember writing in my notebook, with tears: "When night falls on an unlit pitch, I hear the ball roll and call it a poem." Tonight, all of Vietnam is a poem. But how long will this poem last? That is a question I cannot answer. I only know that as I write these lines, Hanoi is turning cold. This winter will be warmer than previous ones, because we have a championship to keep us warm. But spring will come, and with it, the 2027 Asian Cup qualifiers. Our opponents will no longer be Thailand, Indonesia, or Malaysia. They will be Iraq, Japan, South Korea – teams we have never beaten in an official tournament. Will Nguyễn Xuân Son recover in time? Will Kim Sang-sik stay? Will we learn the lessons from this victory? I don't know. But I know that, as I wrote in another poem: "Football lies in the silence between two touches of the ball, where the hearts of spectators score goals on their own." And tonight, my heart scored a goal. Let it resonate for a long time.
