Vietnam U23's dramatic defeat at the AFC U23 Asian Cup: a lesson bigger than tactics

Busan, one morning in April, I sat in front of my screen, trying to grasp the pulse of a match taking place half a world away. On the Al-Janoub pitch, Vietnam U23 had just suffered a bitter 0-2 defeat against Iraq U23 in the quarter-final of the 2026 AFC U23 Asian Cup. I was not there, but through the screen, I could still feel the silence descending after the final whistle. No audience in my mind, but I could still hear the heartbeat of the match. The captain and goalkeeper, Đặng Văn Lâm, who had started throughout the tournament, stood still watching the Iraqi players celebrate. He said nothing, only wiped his face with his hand, as if trying to brush away the sweat still rolling down his forehead. Behind him, the red-shirted defence hung their heads, some covering their faces. That image reminded me of those afternoons in Busan, when I stood outside the training ground watching Korean players go through similar moments. The match began with a balanced contest. Coach Hoàng Anh Tuấn set up the 3-4-3 formation he had used throughout the tournament, a proactive defensive system with Khuất Văn Khang and Nguyễn Thái Sơn shielding the back line. From the first minute, Vietnam U23 showed their intention to press high, preventing Iraq from easily building play from their own half. However, the pace of the match gradually exposed gaps in Vietnam's young defence. In the 23rd minute, from a quick counter-attack, the Iraqi forward sprinted down the right flank, beat two defenders, and crossed into the box. Midfielder Ali Jasim slid in to score from close range, opening the scoring for Iraq. At that moment, the entire stand seemed to erupt, while I only quietly noted in my notebook: "The goal came from speed, not tactics." The 0-1 scoreline at half-time did not reflect everything that had happened. Vietnam U23 controlled 55% of possession, created more chances, but lacked precision in the final moments. In the 39th minute, Khuất Văn Khang struck from distance, hitting the crossbar. In the 44th minute, Nguyễn Quốc Việt had a one-on-one chance with the goalkeeper but shot straight at him. The pulse of the match was still there, but the goal kept escaping their net. In the second half, Coach Hoàng Anh Tuấn brought Võ Hoàng Minh Khoa on for Nguyễn Văn Trường, switching to a 4-2-3-1 formation with the intention of increasing attacking pressure. This change pushed Vietnam U23 higher, creating significant pressure on the Iraqi defence. In the 55th minute, Minh Khoa dribbled past three players and passed to Quốc Việt, but his shot narrowly missed the post. That was the clearest opportunity the red team created in the entire match. However, football is like that. While Vietnam pushed forward looking for the equalizer, Iraq exploited the space behind the defence to seal the game. In the 83rd minute, from a lightning counter-attack, the Iraqi forward sprinted through and finished with one touch, making it 2-0. It was the deciding blow, and although Vietnam U23 pushed forward in the remaining minutes, they could not break through the opponent's solid defensive line. On tactics, Coach Hoàng Anh Tuấn had prepared thoroughly. He required his players to press from the opponent's half, while positioning Khuất Văn Khang deeper to assist in defence. However, keeping the ball without creating enough clear chances was a major issue. Vietnam U23 managed 14 shots with only 3 on target, while Iraq had 9 shots, 5 on target, and scored 2 goals. These numbers do not tell the whole story, but they reveal the difference in efficiency in converting opportunities. There are things that do not show on the scoreboard, yet they decide everything. On spirit, the most memorable moment was Đặng Văn Lâm charging forward to join the attack in stoppage time. He ran up like a forward, jumping for the ball in the box, as if trying to do something for his teammates. That was not a tactical decision, but a call from the heart. And he, a 30-year-old goalkeeper, still had a fierce heartbeat. But I do not want to use the word "failure" for this match. Because football is not just about results. Football is about moments when people overcome their own limits. Vietnam U23 played with all their heart, giving their fans moments full of emotion. They lost a match in which they played better than their opponents for most of the time, but were less efficient in the decisive moments. What is noteworthy here is how Vietnamese fans received this defeat. There was no heavy criticism, no harsh words on social media. Instead, they offered sincere encouragement to the players. One fan wrote on social media: "You gave everything, nothing to be ashamed of. See you at the next tournaments." This shows that Vietnamese football is maturing, not only on the pitch but also in the stands. Compared with what I witnessed in Korea, where pressure from fans sometimes frightens young players, I see warmth in how Vietnamese people accept defeat. Koreans have cried for Vietnamese football, and now I understand why they did. Because Vietnamese football is not just about victories, but also about stories of resilience, about belief in each other. Busan taught me how to keep the beat, and so did this match. I learned that silence is also a way to cheer. As the players walked off the pitch with tear-stained faces, the fans still stood, clapping and chanting the team's name. They did not need to say much, just seeing each other was enough. Looking back at the entire tournament, Vietnam U23 made significant progress. They advanced past the group stage with two wins against Kuwait U23 and Malaysia U23, along with a draw against Uzbekistan U23. They showed a cohesive style of play, a collective that knows how to fight for one another. That progress matters more than a ticket to the semi-finals. Each player has their own rhythm. I just find where it begins. For Khuất Văn Khang, that rhythm starts with composure in every pass. For Đặng Văn Lâm, it is decisiveness in every save. For Hoàng Anh Tuấn, it is persistence with his philosophy. Those rhythms will continue to sound, not only in this tournament but also on the road ahead. There is a question I keep asking myself as I sit in my small room in Busan: Did focusing too much on possession make Vietnam U23 lose their sharpness in counter-attacks? The numbers say they created more chances, yet lost comprehensively on efficiency. Perhaps, in the future, they need to learn to balance between controlling the game and attacking with direct speed. Not every match has an audience. But every match has someone who keeps the beat. And even though this match ended in defeat, I believe these young players have learned a lesson more valuable than any trophy. They learned that winning and losing are only part of the journey. What matters most is that they dared to face the challenge, dared to dream. From Busan to the World Cup, I learned that football does not lie. It shows exactly what you deserve. And Vietnam U23, despite losing this match, still deserves the applause, deserves the trust of their fans. Because they did something greater than winning: they made a small nation in Southeast Asia believe they can stand on the same stage with the strongest opponents on the continent. I turned off the screen and stood up from my desk. Outside the window, the city of Busan was waking up, its yellow lights spilling onto every street. I thought about the young players of Vietnam U23, perhaps now on their flight back home. They carry a defeat, but they also carry a future. And in my heartbeat, the heartbeat of a Vietnamese expatriate, I still heard the heartbeat of Vietnamese football. It is still there, strong and steady.
