The Empty Analysis and the Discipline of Data in Vietnamese Women's Football

That day, a dossier was placed in front of me. It had a complete header, a "football" label at the top, and a neat nine-section template. But when I turned to the body, every box was empty. No title. No source. Not a single information point. Only one cold line: "insufficient data for analysis."

I sat still for a long time. At fifty, after thirty-four years in this trade, I had grown used to reports crammed with numbers, xG charts curving across pages, PPDA tables dense with figures. An empty analysis is a rare thing. But it was that very emptiness that taught me something no thick report ever could: the hardest part of the job is not finding the answer, but daring to admit you do not yet have the question.

And when I think about Vietnamese women's football, I realise we are drowning in similar "analyses" — stuffed with conclusions, hollow of data.

Past the World Cup threshold

In 2026, the Vietnam women's national team walked onto a World Cup pitch for the first time. A milestone. The whole country turned toward Australia and New Zealand. In the stands, on social media, in every coffee shop, people talked about women's football as never before. That was cause for joy. But alongside that attention came a torrent of opinion: who is good, who is weak, how the team should play, whom the coach should substitute.

Most of those opinions contained not one verifiable information point. No numbers. No context. No one stopped to ask: what life is this number hiding?

In the analytical document I read, this is called "analytical contamination." When a framework is empty, the writer's instinct is to fill it with plausible-sounding guesses. And so a conclusion without foundation is born, then spreads, then becomes "truth" in the minds of many.

This is not merely the problem of one article. It is the problem of an entire way of talking about women's football.

After 2026, the Vietnam women's team entered a new cycle. The national women's league remains small in scale. Few matches are broadcast live. Female players still live on modest incomes. In such a context, every remark carries weight. A well-timed criticism can open a door. An unfounded one can close a career.

What I learned from numbers that speak

In 2026, I began a WK League analysis programme on a digital platform. Over six months, I tracked the data of Incheon Hyundai Steel Red Angels. And I found a substitute striker named Choi Yu-ri, who had played only 214 minutes but recorded an xG — expected goals — of 3.2, the highest in the squad.

From the numbers, I saw a person waiting to be called by name.

A month later, she started the final match of the season and scored twice, helping the team win the title. Had I written only by the feel of the stands, I would never have seen her. The feel of the stands is always loud. But it cannot distinguish between a lucky bounce and a player type the system forgot.

That is why I trust data. But precisely for that reason, I learned that data is a double-edged knife. It can illuminate, and it can become a hiding place. When someone offers a number without placing it in context, that number does not tell the truth — it conceals.

For Vietnamese women's football, we need exactly that discipline. Before saying "Vietnam's women press poorly," show me PPDA — the passes allowed per defensive action. The lower the number, the more intense the pressing. Before saying "the attack is weak," show me xG and xG per shot. Before saying "this player is not good enough," tell me how many minutes she played, in what position, against which opponent.

From Choi Yu-ri in Korea to Huỳnh Như of Vietnam — who once played in Portugal for Lank FC — every female player deserves to be judged by process data, not by prejudice.

In 2026, at the Tokyo Olympics, I ran the women's football column. South Korea, under coach Colin Bell, took only one point from three matches. Looking at the table, everyone said: failure. But when I checked, their PPDA was 8.6 — the lowest in the tournament. That meant that despite being physically inferior to European sides, they pressed the most aggressively. I wrote the piece "A Meaningful Failure," analysing the asymmetry of resources. It reached 250,000 reads — the highest of my career.

That taught me: a team can lose on the scoreboard yet win in process data. And the analyst's job is to point that out, not to shout along with the result.

Vietnamese women's football deserves to be treated that way. Not with generic applause, but with analysis specific to every single ball.

When "I don't know" is the most professional answer

Here I want to say something that may irritate many people. In my trade, the greatest temptation is not inventing a wrong conclusion. The greatest temptation is filling a void with a reasonable-sounding conclusion.

The empty analysis I mentioned at the start is an example. It had room for nine sections of analysis: tactics, finance, results, league standing, rules, dressing room, risk, media, transmission chain. If I wished, I could fill all nine with sentences that sound extremely "expert." But all I had was a "football" label and not one information point.

A professional writer must have the courage to say: not enough data. Not out of laziness. But out of respect for the truth. And respect for the people being discussed.

I once made a mistake on this. In 2026, at the FIFA U-20 Women's World Cup in France, during the Korea versus England match, I mispronounced the name of striker Ellie Brazil three times in the first half. I received a wave of criticism. I was so ashamed that I spent the next two weeks reviewing every recording, learning the pronunciation of all 352 players at the tournament.

Mispronounce a name once, remember it for life; correct it, and you treasure it more.

From then on, I built a system of notes on the pronunciation, shirt numbers and biographies of more than 300 female players from 16 countries. I never again accepted carelessness. And I understood: if I do not have the patience to call a player by her correct name, what standing do I have to analyse her game?

That World Cup did not get the name wrong; I was simply not grown enough to say it right.

So it is with Vietnamese women's football. Before rushing to conclude, learn the names, the shirt numbers, the positions, the running distances of each person. That is the foundation work. Without it, every analysis is a building raised on sand.

The phone call in the middle of the pandemic

In 2026, when the pandemic halted every tournament, I lost my working rhythm. Emotionally exhausted, I lay still in my Incheon apartment for three weeks, unable to write a single line. One evening, I video-called Ji So-yun, the legendary midfielder who once played for Chelsea. She told me that at fourteen she had to leave her family to train alone. My tears spilled over.

The phone call in the middle of the pandemic taught me that sport heals without an audience.

Since then, my writing changed. I began each piece with an ordinary moment in a female player's life, then led into the data. Because behind every metric is a person. Behind every substitution is a sleepless night. Behind every goal is a family that sacrificed.

For Vietnamese women's football, I believe the same. Our girls do not need to be tinted into fairy-tale warriors. They need to be analysed fairly, like any male player. That is real respect.

The discipline of numbers, the humanity of people

There is another temptation I want to warn against: defending women's football unconditionally, afraid to criticise tactics. Having devoted a career to championing forgotten women, a writer easily turns them into sacred ground no one may touch.

But I keep one strict standard for both men's and women's football. The greatest respect is fair criticism, not leniency because of gender. If a female defender misplaces three passes that lead to goals, talk about it as you would about a male defender. If a female coach has a good tactic, praise her for that tactic, not because she is a woman.

The truth is: if we lower the standard for women's football, we are implicitly saying it does not deserve to be taken seriously. That is a subtle form of discrimination, dressed in goodwill.

What I want to leave behind

The corridor of women's sport is not only victories, but doors slowly opening.

The 2026 Women's World Cup was one such door. It opened a broader conversation about Vietnamese women's football. But a door is useful only if we walk through it with open eyes and a mind that refuses carelessness.

And perhaps this is what I most want to engrave: in a world full of "experts" ready to deliver conclusions in three seconds, the most decent professional is sometimes the one who dares to stay silent. Not silent out of fear. But silent because they know they do not yet have enough data, enough fairness, enough patience to call a person by their right name.

At fifty, I understand that the pitch has no borders, but the heart has coordinates. And the coordinates of my heart, right now, lie in women's tournaments that have never been seen properly — where every penalty box holds a story no one has told, and every table holds a person waiting to be called by name.
