When Vietnamese Sports Data Remains a 'Lowland': Lessons from an Empty Analysis

I sat in front of the screen, reopening the Stage-2 analysis a colleague had sent over. All nine analytical dimensions — from technique, performance, competition systems to risk and media narratives — displayed the same cold line: 'N/A — insufficient information, cannot assess.' No numbers, no names, no events were recorded. I suddenly recalled my own words from World Cup 2026: 'From a mispronunciation during the World Cup, I understood that football doesn't begin with the feet, but with the ear.' Today, I understand one more thing: Vietnamese sports don't begin with victory, but with data — and our data is a vast lowland.

The empty analysis was not the fault of its author. It reflects a painful reality: in many domestic tournaments, we have no data collectors, no storage systems, no standardized information. When a V-League match ends, we know the score, we know the goalscorer, but we don't know the pressing count of the central midfielder, the distance covered by the full-back, or the pass completion rate in the final third. Meanwhile, in Europe, a third-division English match generates more data than a Vietnamese National Cup final.

I remember Euro 2026, when I manually timed Federico Chiesa's pressing count in Italy's match against Turkey. 34 times — a figure I discovered not from any statistics website, but from my own patience. The article 'Chiesa – The Fire Man, Not the Star' was born from that, and it was widely shared. But I ask myself: in Vietnam, how many young players are performing well without anyone noticing, simply because no one counts, no one records, no one analyzes? How many 'silent Chiesas' are being forgotten in the darkness of data scarcity?

Pressing data cannot lie, but they whisper the name of a star still dreaming. This saying of mine has never been truer than in the current context. When I followed matches at SEA Games 32 in Cambodia, I noticed something: the Thai, Indonesian, and Malaysian teams all had dedicated data analysis units, with specialized software open on laptops in the stands. And us? We rely on the intuition of coaching staff, on the experience of former legends, on the luck of a moment. That's not wrong, but it's not enough for a football nation aspiring to reach the continental level.

Look at how the Thais operate. They have a national data system where every match, from youth to professional levels, is recorded, analyzed, and stored. When a 17-year-old player in the Thai third division makes 12 successful tackles in a match, that number immediately enters the system, and three months later, he might be called up to the national U19 team. In Vietnam, a talented young player could perform well for an entire season without anyone recording his tackle count. The difference lies not in talent, but in the talent-detection system.

I once wrote in a World Cup 2026 analysis: 'Qatar is hot, but the transfer shock that year was hotter than the desert wind.' In Vietnam, our shock is not transfers, but the silence of data. When I wrote the exclusive story about goalkeeper Nguyễn Văn Hoàng's move to CLB Hà Nội in November 2026, I had no database to consult. I relied on sources, on cross-verification, on 11 years of professional experience. But I wonder: if we had a standardized transfer data system, could I have detected the story earlier, and could clubs make wiser decisions?

A player truly speaks when the ball lies between his boot and my curiosity. That curiosity needs to be nourished by data. I'm not saying we should mechanically copy the European model. We need a system suited to Vietnam's conditions — low cost, easy to deploy, compatible with existing infrastructure. A tablet with a simple note-taking app, a well-trained volunteer, a standardized data process after each match — these are humble but practical first steps.

I remember Paris 2026, when I entered the press conference after the women's football final between Spain and Brazil. An older male journalist whispered, 'What would a woman know about pressing?' I didn't respond, but that night I wrote a match report that turned the Spanish team into a symphony — where attacking players were the high notes, the midfield the bass keeping rhythm. The article became one of the most-read on the Asian Football Confederation's homepage. I tell this story to illustrate a point: data is not dry, if we know how to tell stories from it. But to tell stories, we need data first.

Hearing the crowd roar, I know I'm writing with sweat, not just ink. My sweat is the sleepless nights watching match footage, the times I manually timed pressing counts, the phone calls verifying information with agents. But my sweat cannot replace a system. I can count 34 presses by Chiesa in one match, but I cannot count 34 presses by a young Vietnamese player in a season — because there's no complete footage, no standardized data, no one recording.

The empty analysis I received today is a wake-up call. It's not the fault of the analyst, but the fault of an entire sports ecosystem that hasn't yet considered data a national asset. When we have no data, we cannot assess, cannot compare, cannot detect talent, cannot make sound tactical decisions. We are swimming in darkness, while our competitors have long turned on their headlights.

From pressing to goal is a long journey, like me learning to pronounce my own name again. Vietnam's journey from a data-poor sports nation to a data-driven one is similarly long. But every journey begins with a first step. That step could be a small investment in a data collection system, a training course for statistics volunteers, or a regulation requiring clubs to submit match data to the federation. When we have data, we will have stories. When we have stories, we will have recognition. And when we have recognition, we will have complete analyses — no more cold 'N/A — insufficient information' lines.

Each sport is its own universe, and I am fortunate to be a traveler between those orbits. But a traveler needs a map. Data is that map. And our map, currently, still has too many blank areas. It's time for us to pick up the pen and start drawing.
