Heat Maps Don't Tell the Truth: Why Vietnam's Wingers Are Being 'Neutralized'

At about 4:30 PM on June 6, 2026, at My Dinh Stadium, I stood in the corridor of the dressing room. The training session of the Vietnamese national team had just ended, and wingers like Nguyen Van Toan or Pham Tuan Hai left the pitch with expressions not very excited. They had just spent nearly 30 minutes practicing inward movements – a tactical requirement that has become a 'golden rule' under coach Philippe Troussier. The heat map of the Vietnamese national team in the match against Indonesia in the 2026 World Cup qualifiers (March 2026) is being widely shared on social media. The image shows that attacking players do not hug the touchline. They drop deep, cut inside, creating a crowded block in the area just outside the opponent's penalty box. Many commentators say that Vietnam controls the ball well, but in reality, they are stuck in their own style. For me – a person who has followed Vietnamese youth teams for over 9 years – this is not a problem of individual technique, but a tactical philosophy that is distorting wingers who were born to cross and stretch the spaces. Let's look back at Vietnamese football in 2026-2026, under coach Park Hang-seo, or even earlier with generations such as Cong Phuong, Van Toan, Trong Hoang. They hugged the touchline, crossed the ball, or dribbled past defenders and cut back. The national youth teams did the same. In the U19 squad that won the 2026 Southeast Asian Championship, I had the opportunity to watch every match – young wingers like Nguyen Quoc Viet or Nguyen Thanh Nhan often made crosses from the wing, creating opportunities for the striker to finish. But under Troussier, everything changed. His 4-3-3 model requires the two wingers to operate as 'number 10s' in the middle. They are encouraged to receive the ball from central defenders, maneuver in tight spaces, and make through balls. Looking at data from the last 10 matches of the national team: crossing attempts from wide areas decreased by 42% compared to the 2026-2026 period, while dribbles cutting inside increased by 28%. However, goal efficiency decreased: shot conversion rate dropped from 14% to 9%. The problem is not that 'crossing is good' or 'exploiting the middle is bad' – the issue lies in the fact that we are eliminating an important attacking dimension. The world has seen how Morocco reached the World Cup 2026 semi-finals thanks to the flexibility of wingers like Hakim Ziyech, who could both cross and cut inside to shoot. Or at Manchester City, despite using inverted wingers, they still always have a full-back pushing high as a crossing option. Modern football does not deny the role of the wing; they combine the two to create unpredictability. But why does Troussier, who helped Japanese football advance remarkably, apply a somewhat rigid model to the Vietnamese national team? The answer may lie in the squad characteristics. Our center forward is not strong enough to compete in the penalty area, so crossing becomes less effective. Therefore, he shifted to playing on the ground, asking wingers to constantly move into central areas to create numerical superiority. This is a reasonable adjustment in theory, but it breaks the 'essence' of Vietnamese attacking players who are naturally muscular and direct. Let's look at a specific number: in the match against Iraq in the third round of the 2026 World Cup qualifiers (September 2026), Vietnam made 11 crosses from the wing, completed 2, and none created a shot. Meanwhile, our only goal came from a central combination between Nguyen Hoang Duc and Nguyen Van Toan. In theory, this is a correct tactic, but looking at the overall match, Iraq's defense pushed high and blocked every pass into the middle. We lack a real winger to stretch the defense – from my observations at the press box, I clearly noticed that. Iraq only needed to press our two central defenders to neutralize our entire midfield, because our wingers did not hug the touchline, making it easy for their markers. I start from youth data; every number is a drumbeat before kickoff. When I reviewed videos of the U19 championship-winning generation in 2026, I clearly saw the change in how young players move. They no longer habitually dribble to the byline and cross, but instead receive the ball in midfield and pass to teammates. That makes me wonder: are we creating a generation of 'blunt' wingers? There are too many heat maps, too many positional drills, and not enough 1-vs-1 sessions on the wing, not enough crossing and heading exercises. My opinion, developed over many years covering F1 and football, may be hard to hear for those who believe in possession football: it is this so-called 'possession' that is killing creativity. Players like Nguyen Van Toan, famous for his speed and dribbling skills, are now confined to a narrow area between two defenders. He cannot use his strength of dribbling along the wing but must constantly maneuver in tight spaces. Statistics show that Van Toan's successful dribbles for the national team decreased from 2.1 per match (2026-2026) to 0.8 per match (2026-2026). That is proof that this style has eroded his strengths. The story is not limited to the national team. The current youth system is also following Troussier's model from his time as VFF technical director. Academies such as PVF, Nutifood JMG, and Hoang Anh Gia Lai are all trained with possession-based methods, emphasizing short passing rotation and smart movement. However, when watching youth tournaments in recent years, I rarely see high-speed dribbles on the wing that lead to crosses. Instead, we see many triangular combinations in midfield, then deadlock. When the stadium is silent, I learn to listen to the team through my pages of notes – the numbers are telling us that Vietnamese football is losing a crucial part of its attacking identity. However, there is a paradox. If we look at the results, the Vietnamese team under Troussier has maintained its top-3 rank in Southeast Asia and had impressive victories against Thailand and the Philippines. Their average ball possession is 65%, much higher than the previous period. So is my skepticism wrong? It must be acknowledged that those victories often came against weaker opponents, where we could hold the ball without facing much pressure. When encountering well-organized defensive teams like Iraq, Japan, or Australia, the team's ability to create chances is very low. In the third round, they scored only 3 goals in 6 matches, of which 1 came from a set piece, 1 from a counter-attack, and 1 from an opponent's individual error. No goal came from wide attacks. I do not deny the value of possession football, but I believe that a hybrid between possession and direct play is the way for Vietnamese football to reach Asian standards. Look at Japanese football after Troussier left: they developed versatile wingers who can play wide, as playmakers, and can cross even without a strong aerial center forward. It is not necessary to abandon the current formula, but adjustments are needed so that wingers are not 'boxed in' to a single role. In a private conversation with a U23 assistant coach after a friendly match in October 2026, I heard: 'We want attacking players to be flexible, not too rigidly tied to the wing.' That may be true in theory, but in practice on the field, they still lack a forward who pins wide to create space. The World Cup door opened thanks to a relationship; but I keep it open with consistency – this is my mantra when dealing with sources. And I see that Vietnam does not lack talented players, but lacks a tactical environment that respects the diversity of attacking options. Data from domestic leagues like V-League also show something similar: goals scored from crosses account for about 32% – a significant proportion, but in the national team, that number is less than 15%. Some will say: there have been many advances from the wings, but the full-backs play an important role. But full-backs cannot be the sole burden for two wide players and the central striker at the same time. This raises a question about squad balance. Finally, I want to emphasize that a heat map is only part of the picture. A heat map shows positions, but not whether a player provides unpredictability. A winger in the middle might receive the ball 60 times and make 5 key passes, but he still may not pose a real threat if he only moves back and forth without intention to penetrate. Looking at data from a media company's analytics department, I found that in the last 10 matches of the national team, our midfield and wings produced only 23 successful take-ons – a very low number compared to seeded opponents. What does that mean? We control the ball but do not control space. The rhythm of a team is not born on the pitch, but is maintained on rainy days. When I was a journalist at Brentford, I learned to look at youth data to predict the future. Now, watching Vietnamese academies, I fear that there will not be many real wingers anymore. Look at the current generations of U15 and U17 national teams: they are taught to control the ball, but will they have the skills to beat a full-back from the wing to the inside? Who will deliver those devastating crosses in an era when center forwards are getting rarer? I asked this question to a foreign tactical analyst working at VFF, he replied: 'You cannot expect a society still accustomed to emotional football to immediately adopt modern tactical football. We are building a foundation.' Maybe, but as a person who nurtured a passion for the wing penetrations of players like Nguyen Van Toan, I believe that every football nation needs to maintain diversity. If we sacrifice that diversity just to gain possession dominance, we may succeed at the regional level, but will face great difficulty at the continental level. People write about goals; I write about the silence before the ball hits the net. That silence is the anticipation of how a player will act in a tight space. But when the game lacks direct duels as before, those moments are becoming rare. I don't have a definitive answer, but I can point out that if we look at data over the next 5 years, we may witness the return of wingers who can cross, because Vietnamese football needs them to touch the World Cup dream. Every contract is a film shot from the time the player trained in a dusty field – but let them practice crossing, let them be themselves. For 9 years I have stood on the touchline, and I have seen too many young players trained to be obedient tactical machines while forgetting improvisation. Data is not in a hurry; it waits for me to read carefully before trusting emotions. And my emotion now is nostalgia for wingers who could 'blind' opponents, then cross low to a striker. The modern era may differ, but the instinct to win remains. I keep the rhythm; football finds those who listen. For the Vietnamese national team, I will still listen on rainy days at My Dinh, waiting for a cross to revive the identity. Are we going too far with the possession style? Or have we not yet refined it into a sharp weapon? I do not have a complete answer, but I believe this is the question everyone who loves Vietnamese football should ask. Looking at world football history, the most successful teams always balanced possession and directness. Spain won the 2026 World Cup with possession-based football, but they still had wide attacks from Sergio Ramos and Jordi Alba. Manchester City under Pep Guardiola may dominate possession, but their important goals often come from wide situations. So the issue is not necessarily the choice of philosophy, but the flexibility in tactical situations. This is what Vietnam is missing. In the near future, in August 2026, the team will play friendlies against Saudi Arabia U23 and Lebanon. This is an opportunity for Coach Troussier to try different attacking options, allowing players like Xuan Son (if naturalized) or Nguyen Van Toan to play with a real striker, or using wingers who tend to hug the touchline. But ultimately, fans do not wait for friendly results; they wait for direction. I hope that in the coming days, training sessions are not just repetitive positional drills, but a place for wingers to showcase their strengths. Because once wingers are choked, the team becomes a rotation machine without a blade. Data never lies. Looking at the technical indicators of the national team in the last 20 matches, I see a trend: the number of shots from outside the box increased, but the number of goals from central combinations did not increase correspondingly. This proves that long-range shots become a last resort when we cannot approach the goal from the wings. Again, the reason lies in the lack of wingers who truly make a difference in the opponent's final third. I am not optimistic that things will change immediately. Changing a system built over 3 years is not easy. But I believe in the value of honestly assessing current limitations and fixing them gradually. Vietnam owns a generation of players aged 24-27 who are at their peak, but they need a tactic that exploits directness. Focusing on possession without a genuine threat from the flanks will not bring the team closer to the 2030 World Cup – a goal VFF has set. In the immediate future, at the 2026 AFF Cup, if they face Thailand, Philippines, Indonesia – all have fast wingers – we will face more difficulties if we cannot play out wide. After all, and no matter how much analysis I make, I am still just an outsider. But I have traveled from Hanoi to Ho Chi Minh City pitches, watched hundreds of matches, and I know that wingers always bring thrilling moments to fans. There is a saying I often use: 'People write about goals; I write about the silence before the ball hits the net.' That silence, before a cross from the wing meets a striker's head, is the moment that makes people love football. And I hope that moment will return to Vietnamese football. Then, the heat map of the national team will look beautiful not only in the middle of the pitch, but also with highlights along the wings. That will be the moment when we know that tactics do not bind talent but elevate it.
