After the Legends' Farewell: Decoding Vietnam Football's Fitness Hunger in the New Era

The national stadium was drowned in a sea of red flags with yellow stars, but the moment I remember most was not a goal or a save. It was the image of a winger, after more than 90 minutes on the pitch, collapsing right as the final whistle blew. The referee had left, the crowd had started singing victory songs, but he was still lying there, gasping for air, legs trembling with exhaustion. No one noticed. The scoreline was good; everything seemed perfect. But in that moment, I saw a bigger question than victory: Is Vietnamese football ready for the long road ahead, or is it still just sprinting in short bursts of joy?

The context here is no longer the early days of the golden generation. The national team has experienced a historic cycle of success with achievements in the AFF Cup, SEA Games, and the World Cup qualifiers. But every cycle has an end. The pillars of that glory have stepped past their peak. And while fans still mourn as legends say goodbye one by one, a harsher reality emerges clearly: the next generation must replace not only the talent, but also confront a problem few dare to speak of — fitness.

Anyone who has watched Vietnam's national team regularly in the last two years will notice a worrying pattern. The deeper into a match, the slower the pressing tempo. Attacks on the wings lose their sharpness from the first half. And most notably, late goals conceded are no longer exceptions. There was a time when Vietnam's high-pressing style completely overwhelmed Southeast Asian opponents in the first 60 minutes. But what happens afterward?

Look back at a recent friendly against a West Asian team, when the home players began to visibly run out of breath from the 70th minute. Passes became inaccurate; the distance between the three lines stretched like a rubber band about to snap. A coach can rotate his lineup, can make three or four substitutions, but he cannot substitute the fitness of a whole collective drained by a congested schedule.

My story begins precisely here. In my 17 years observing Southeast Asian football, I have never seen a national team sustain high intensity over a long tournament without a truly strong medical and sports science team. Huge investments in stadiums, youth training centers, and foreign coaches are all necessary. But in an unnoticed corner, the physiotherapy room, the recovery chamber, and the heart-rate monitoring devices are where a team's true ceiling is decided.

Compare this to how Thai football, our longtime rivals, has operated. They don't only have excellent technique. They have synchronization between clubs and the national team. When players are called up, Thais almost already have a fitness foundation up to standard. For Vietnam, many players must go through a phase of 'recharging' fitness every time they join the national team. This gap is not always visible to the naked eye. It is in the numbers, in the data on distance covered, in the number of sprints at the end of matches.

The difference between winning a match and winning a whole tournament lies in fitness reserves. It is measured by the silence between two passes when the match is at minute 80.

I recall a visit to a high-performance sports center in Hanoi, where a team doctor showed me the blood glucose charts of players after heavy training sessions. He said a sentence I will never forget: 'Fitness is not about how many kilometers you can run, but how your body reacts when your brain is already starved of oxygen.' He told me that recovery between World Cup qualifiers was almost a race against time. Within just three or four days, players must fully recover from 90 minutes of high intensity. If this recovery phase fails, every tactical plan becomes meaningless.

This leads to a paradox I have witnessed over 8 years of reporting in Shanghai, following Chinese clubs in continental competitions. Many good players with great individual skill and burning ambition still lose to Korean and Japanese teams with fewer stars. The secret is in fitness preparation over the whole season. They don't let players peak during pre-season friendlies only to fade away afterward.

Data on the distance covered by Vietnamese players in international matches shows a clear trend: we tend to play at very high intensity in the first half, especially at home. But in the second half, especially after the 65th minute, these numbers drop significantly. Meanwhile, teams like Malaysia, Indonesia, and Thailand — those that have invested heavily in domestic leagues and recruited naturalized players with strong physiques — maintain a steadier intensity.

In recent World Cup qualifiers, I remember a match where our defense had to absorb constant pressure for the final 20 minutes. The opponent pushed high, creating enormous pressure. Vietnam's center-backs, despite good positioning, were beaten in seemingly harmless situations. The cause is simple: their legs were no longer quick enough to turn, no longer powerful enough to jump. This deficiency has nothing to do with technique.

When the attack lacks tactics, people think of substitutions. But when the defense begins to slow down, one must think back to the gym and the dining table.

Why is this issue rarely discussed frankly? Perhaps for a delicate reason: speaking about the fitness of Vietnamese players can make people feel you're disparaging their effort. Vietnam has improved so much technically and tactically. But the physical gap — height, strength, recovery ability — is a major barrier.

However, I am not talking about race or genetics. I am talking about management. The team has done part of the job, but it has only addressed the problem of training volume, not yet refined the problem of quality recovery for each individual. Nutrition for each position, sleep schedules, stress management — it is all a system. If one link is missing, the whole chain cracks.

Another angle rarely seen in Vietnamese football analysis is the lack of public data on player readiness. In European leagues, clubs publish metrics like injury frequency, average recovery times, or training completion percentages. These numbers not only help journalists analyze but also help fans understand why a player struggles. When Vietnamese football opens up more to data, fans won't be so harsh when a player underperforms: they'll understand he might have just endured a high-intensity training block or a series of matches with insufficient rest.

I remember, years ago, talking with a retired national team player. He described the loneliness of battling injury without adequate psychological support. 'Everyone sees the player on the pitch. Few see 2 AM, when an injury torments you, and you lie alone in your room, not knowing if you can play tomorrow.' His story is about a lack of a comprehensive care system. As the golden generation of Vietnamese football closes, this story becomes all the more urgent.

There are apologies that don't need forgiveness, only a stadium wide enough to contain them. Here, the stadium is the medical, nutritional, and recovery system of a football team.

What do fans expect from the national team now? Victories, of course. But sustainable victories only come when the team's foundation is strong. The next generation has talent — yes. But young talents from local academies are still not fully equipped to play high-intensity football in the region's demanding environment.

Young players like Phan Tuan Tai of Hanoi FC, or Nguyen Dinh Bac, who impressed at youth level, show technique and confidence are improving compared to the previous generation. But technique alone is not enough. They need a club environment where fitness is treated as part of tactics, not a side condition. The domestic league has better competition now, but the number of matchdays each season is still limited compared to continental standards. This directly impacts the ability to accumulate experience and maintain peak match fitness.

Another point must be raised: the approach to squad rotation. The French coach built a disciplined style, but rotation decisions by subsequent domestic coaches have remained somewhat instinctive. Selecting the right player for the right match is an art, but that art must be supported by the physical reality of the players. If a player is in great form but faces a congested schedule, sometimes the best solution is to rest him for one match, even if the team may lose. This is the mindset of sacrificing immediate gains for long-term interests.

The foreign player quota is also part of the story. The domestic league is increasingly dependent on foreign forwards. This inadvertently limits opportunities for domestic strikers. When they join the national team, they lack match sharpness and have only accumulated fitness from training, not from high-stakes matches. Vietnamese center-backs, on the other hand, are constantly tested by physical foreign attackers in club matches. This partly explains why the national defense often holds firm while the attack lacks sharpness.

Amid transfer numbers and billion-dollar contracts, I found the heartbeat: a belief that a Vietnamese player can shine on the continental stage if placed in a truly scientific system.

On data, xG analyses show the national team can create chances comparable to regional rivals. But the conversion rate of chances into goals in late match phases often drops. The cause is not only tension in finishing, but also the strikers' fading fitness to maintain composure and precision in final actions. When the body is tired, technique erodes.

If I may suggest a direction for Vietnamese football, we must accept a fact: there cannot be a strong national team if the domestic league is not demanding enough. A demanding domestic league is not just about having more clubs or more matches; it's about professional quality and sports medicine infrastructure meeting standards. Participating clubs need support to build recovery rooms, equip motion-tracking technology, and hire internationally certified fitness specialists.

Looking at Indonesian football: they haven't produced a golden generation like Vietnam, but they have enormous determination to improve fitness by naturalizing players of European descent and building academies with modern standards. Their story proves that at national team level, fitness is the shortest shortcut to closing the quality gap.

For fans, there is a comfort: fitness is improvable. Height is hard to change, but stamina, acceleration in single moments, and pain tolerance can all be trained. So the challenge rests with the coaching staff, youth development programs, and long-term planning.

It would be unfair not to mention those silently working day and night in sports centers. There, physiotherapists can only communicate with their eyes after scorching summer afternoons. There are doctors who must decide in minutes: let this player continue or pull him out. That decision is not just professional; it requires the courage to bear responsibility.

Football is a sport of microscopic errors. A pass off by half a meter, a step slow by half a beat, a jump short by two centimeters. All these errors, from a fitness perspective, are products of a long process. As our golden generation says goodbye, the young players inherit that glorious legacy. They will write their own stories. Hopefully, when that story is written, they won't be left alone in the fitness race at the final lap.

These lines are not written to criticize or condemn. They are written out of love for the game, out of a desire to see Vietnamese football step out of the comfort zone of superficial glamour and into sustainable values. Because a strong team is not only shown by the trophies it lifts but by how its players walk off the pitch with legs no longer trembling from exhaustion. And then, when the final whistle blows, they will stand tall — not only because of willpower, but because of a physical foundation built over many years from domestic football.
