In my small apartment in Nha Trang, there is a spreadsheet I open almost every morning. It has every column header in place — passes, successful tackles, distance covered, duels, pass accuracy — but the body of the sheet is empty. Not a single row of data. It is the statistical sheet of a women's football competition I followed for a whole season, and no official source provided enough numbers to fill it.
That empty sheet taught me more than any full one. Because every time it is empty, a familiar voice rises in my head: just estimate a few numbers, no reader will check. Just add "it seems" and "roughly," and a complete analysis will be born within twenty minutes. That temptation is the single greatest point of collapse in the trade of sports journalism.

I have spent forty-three years observing this industry, from the newsroom of a football paper in Madrid in 2026 to the stands of World Cups, Olympic Games, and the Giro d'Italia and Tour de France. I have covered eight Olympic Games and eight World Cups. And the greatest lesson I learned did not come from a match, but from a void.
A women's game counted on faith
People often say men's football data has become an industry. Every Premier League match generates hundreds of data points, from expected goals to pressing indices, from each player's running distance to the angle of the foot at the moment of the shot. Women's football is different. In many competitions, the most basic data — completed passes — still waits for a reporter to sit down and count by hand.
Look at the reality of Vietnamese women's football. The national women's championship has eight teams and plays a round-robin, but not every match is fully filmed. Some matches yield only a few minutes of a news package. When there is no footage and no data, the writer is forced to rely on memory, on feeling, on what others recount. And memory is where bias breeds fastest.
This is the context I call the season of voids. When a major tournament approaches — the 2026 SEA Games 29, for instance — reader demand spikes. Everyone wants to read about the women's national team, about Huỳnh Như, about the chance of a gold medal. But the supply of data does not rise with it. That gap between demand and supply is fertile ground for invented numbers.
Back then, in the newsroom where I worked, some commentaries were written within thirty minutes before deadline. The writer had no footage. They wrote from memory. And memory always favours the familiar: a beautiful free kick, a solo run by a star, a goalkeeper's mistake. The dry tactical details — a stretched midfield, a full-back not pushing high — were ignored. Women's football, written without data, became a sentimental story about pitiable people rather than a contest of wits on a pitch.
How the number-faking machine operates
I want to tell of an incident that taught me a lesson about honesty. In 2026, at the World Cup in Russia. I was one of three Vietnamese women reporters sent to cover the tournament. During a live radio commentary, I mispronounced the name of midfielder Aleksandr Golovin three times. Listeners mocked me. The clip spread. The online crowd called me incompetent.
I could have made excuses. It is a difficult foreign name, I could have said. But an excuse is a form of lying. Instead, I spent the following month rewatching all 64 matches of the tournament. I wrote down the pronunciation of the names of 736 players. I built my own reference dataset, and I never let myself mispronounce a name again. At the end of that year, I published an analysis of the correlation between passes and goals at the tournament, and many senior colleagues recognised it.
That story seems small. But it shows how the number-faking machine works. When a writer feels pressured to have an answer to every question, and the data does not exist, they have three choices. One: admit there is no information. Two: write only what they directly observed, however little. Three: fabricate. Most choose three. Not because they are bad. But because choice one requires courage, and choice three has no immediate consequence.
The number-faking machine runs on a frightening loop. A fabricated number in one article is cited in another. The second cites a third. By the tenth article, the fabricated number has become "official data." The final reader cannot tell truth from illusion, because both are presented in the same steady tone.
What is most dangerous is when the fabricated number supports a pre-existing bias. For example, when people say women's football is "slower" or "less technical," they often attach a number no one has verified: "women run ten percent less than men." No one knows where that number came from. I have searched many sources, and most scientific studies on distance covered show a far smaller gap than the bias suggests, while collision density and acceleration counts have their own distinct features rather than being "inferior" in any evaluative sense. A fabricated number, when it matches an existing bias, is believed more easily than real data.
A lesson from an empty sheet
In modern data analysis there is a concept I cherish: the null result. When a model lacks enough data to reach a conclusion, the professional move is to state plainly "insufficient information to assess," not to fill the table with a guessed number. An honest model knows how to say it does not know.
I have witnessed the opposite. In a consultation meeting for a women's football analysis project I took part in, someone proposed to "fill" the empty cells with the league average. It sounded reasonable. But all it created was a shell of completeness draped over a hollow body. When data that never existed is replaced by an average, every analysis computed on it becomes a systematic lie.
I learned this not in a meeting room, but in the pandemic. In 2026, when global competitions paused, I sank into anxiety — like everyone — and threw myself into research to soothe it. I collected data from 890 matches across five European top divisions before the pandemic, and 278 matches played in empty-stadium bubbles. I wanted to answer one question: how much home advantage remains when there are no fans?
The result made me check it several times. Home advantage fell by about 61 percent with empty stands. I wrote a piece titled "The Twelve-Man Wall Has Fallen," and it became a document many coaches consulted when planning away tactics. But what I remember most is not the 61 percent. It is that I had to refuse to publish many other tables, simply because the input data was insufficient for a conclusion.
There were weeks I sat before my computer with an attractive hypothesis and a dataset sufficient only to "suggest," not to "prove." The temptation to write a complete piece was enormous. But I recalled what my teacher said at journalism school: an honest writer is not one who has never erred, but one who knows when to stay silent. The emptiness in my spreadsheet, therefore, is not a failure. It is proof that I did not sell the truth for a byline.
The pitch has no gender, but the gaze at women on the pitch does
Back to the SEA Games 29 final. When I sat counting Vietnam's 312 passes against Thailand's 198, I was not counting merely to prove which team passed more. I was counting to break a lens. That lens is what an entire society puts on when it looks at women playing football. Through it, a three-player combination becomes "the girls' effort." A structured press becomes "enthusiasm." A tactical error becomes "femininity."
The pitch has no gender. The scoreboard does. When Huỳnh Như drops deep, receives, turns and releases to the flank, that is a tactical act that can be described in the language of men's football without adding a single word about gender. But commentators often do not. They say she "plays like a man" — a compliment that is itself an insult, because it assumes good qualities belong to men, and that women can only reach them by imitation.
For years I tracked how women players were described at World Cups. I wrote down every phrase. "She plays like a man." "A shot as powerful as a male player's." "It is surprising that a women's team has such a clear tactic." Each sentence is a brick in the wall of bias. And the sad part is that these bricks are often laid by people entirely unaware they are building.
We watch the World Cup to see football. But I watch it to inspect the lens people wear when they look at me. That lens is not only on the noses of spectators. It is on the noses of editors, sponsors, and those who decide broadcasting rights. It decides that a women's match will have fewer viewers, not because quality is lower, but because it is sold to the public with a less compelling story — usually one of sacrifice and pity, rather than a contest of wits.
Without a crowd, home is just an address on a map
There is a paradox I have spent years dissecting. Women's football has an economic base so thin that the concept of "home advantage" — one of the firmest laws of football — becomes fragile. When the stands are empty, when a match is played in a stadium few attend, home advantage collapses. I measured this across 278 bubble matches with no fans, and the 61 percent drop told me something larger than a statistic.
The larger thing is this: home is not a place, but a community. Home advantage does not reside in the grass, in the size of the pitch, in the away team's tiring flight. It resides in the roar of the fans, in the pressure they place on the referee, in the confidence they transmit to the home players. Remove the crowd, and you no longer have a home team. You have eleven people standing at an address on a map.
For Vietnamese women's football, this carries deep economic meaning. In a match with empty stands, the home side loses almost all advantage. Women players, already disadvantaged in every aspect of investment, are stripped even of the most equalising weapon — the support of the crowd. But this is also where the larger story of women's football's survival emerges: if a women's team can only survive when people come to watch, then its existence depends not on talent, but on public taste.
I do not need to be welcomed; I need a seat worthy of my work. I wrote that line for myself, but it applies to women players too. They do not need pity; they need a pitch, a stand, a dataset, an attention worthy of the effort they put in. Without a crowd, the away team laughs more — because it knows the home side has no one behind it.
Transfers: where fans' hopes are traded
Transfers are where hopes are bought and sold with the owner's money. But in women's football, that market barely exists. Most women players move on free transfers, on short contracts, on wages so low it is hard to call it a profession that sustains a life. There are no large fees, no blockbuster deals, and therefore no whole industry of speculation born around them.
I once followed the transfer of a promising young women's player from a central province to a bigger club. The story had no fee. No grand press conference. No number for news sites to sensationalise. She left her hometown, moved to another city, stayed in the team dormitory, and started over. If this were men's football, the story would have been packaged as a legend of perseverance. But because it is women's football, it was quietly ignored.
The data void here is not only about match statistics, but about value. When you have no valuation figure for a player, it is hard to defend her against indifference. Women's clubs lack ticket revenue, sponsorship, broadcasting rights. Without money, no analysis. Without analysis, no story. Without story, no audience. That vicious circle reproduces itself every season, and every season it erases another layer of memory about players who gave their entire youth.
Youth development: when physicalisation destroys the technical soil
In youth academies there is a trend I regard as a quiet threat: the pressure for results makes coaches favour physique over technique. At U18 level this is especially clear. A coach needs wins to keep his job, so he picks players who matured physically early — taller, stronger, faster — regardless of whether they have a technical foundation. Smaller players, late developers with good football intelligence, are pushed to the margins.
In women's football this trend is crueller still. At puberty, the physical gap between girls can be very large. An impatient coach will pick the early-maturing, bigger girl as a centre-back or striker, and discard the girl who can pass and handle tight spaces. When those bigger players mature and lose their relative physical edge, they have no technique to compensate. And the technical players who were abandoned have long since gone to other jobs.
This is why I always remind myself that any analysis of women's football must start from the development context, not from match results. A women's team does not play unattractively because it does not want to, but because the system eliminated its technical players when they were fifteen. If you look only at the match and not at the academy, you will blame players for mistakes adults made against them.
Fairy tales consumed and discarded
Every few years a fairy tale appears: a small, poor women's team overcoming everything to win. The media flocks. Emotional articles are widely shared. A week later, everything returns to normal. No investment rises. No audience returns to the stands. The story has been consumed and discarded.
I call this the fairy tale of the lower league. It satisfies the public's emotional need without demanding any structural change. Real reform — redistributing resources, investing in facilities, building a depth of competition — never comes. Because reform does not generate viral articles. It only generates quiet changes that take years to show.
This taught me something about choosing stories to tell. Rather than chasing the fairy tale everyone tells, I seek stories that reveal structure: which women's team was granted training land, who pays the coach's salary, how broadcasting rights are shared. Those are dry stories few read. But they are the truth, and the truth is more useful than a cute myth.
More data is not the answer
Here I want to offer a view contrary to my own intuition of years ago. I once believed the solution to every problem of women's football was data. More numbers, more charts, more models, and bias would be pushed back. But after forty-three years, I must say that belief, unless tempered, can itself become a new trap.
Because data is not neutral. How you measure, how you choose metrics, how you set variables — all derive from a gaze already shaped beforehand. If you measure women's football only with criteria designed for men's football, you will always find it "inferior" somewhere, and that is the fault of the ruler, not the measured. If you count only what is easy — goals, tackles — you will miss what is hard to count, such as how a women's team builds dominance through passes that do not immediately produce goals but strangle the opponent minute by minute.
More dangerously, once you have enough data to project professionalism, you can use it to confirm your own bias. This is confirmation bias. You select the numbers that support what you already believe, and ignore those that do not. A number-faking machine does not have to fake. It only has to select. And selection is subtler, harder to detect, and therefore more dangerous.
The same applies to the "hero against the system" narrative. I once wanted to write about women players as lone warriors against a male-dominated world. But the data showed me a more complex picture. Bias does not exist because one villain operates it. It exists because thousands of unconscious hands hold it: editors choosing sensational headlines, sponsors avoiding risk, audiences accustomed to an easy story, and women journalists themselves sometimes learning to write to a template to get published. Blaming one person does not help us understand the system. Only looking at the whole chain of hands can help us change it.
And here is the greatest paradox: the way to fight both the number-faking machine and the trap of selective data is not more data, but discipline. The discipline of self-verification. The discipline to say "I don't know" when I don't know. The discipline to refuse to publish a number just because it is pretty. These disciplines are not glamorous, do not generate viral articles, do not bring engagement. But they are what build dignity for a sport, and for those who write about it.
The change is happening
The change I await does not come from a resolution or an advertising campaign. It comes from voids being filled slowly but honestly. In Vietnam, more and more women's matches are fully filmed. More competitions have official statistics, however crude. Women's clubs are beginning to have data analysts, even part-time. And most importantly, more young reporters understand that their value lies not in how confidently they speak, but in how carefully they verify.
I write this piece as a reminder to myself, and to anyone holding an empty dataset. That empty sheet is not an enemy. It is an honest invitation: choose silence over fabrication, choose one small true observation over one grand lying conclusion. A missed shot can teach us more than a title, if we are willing to look at our own gaps. And an emptiness in a data table can teach us more than a perfect analysis, if we are willing to face the truth that we do not yet know.
Equality is not about flattening passion, but about ensuring everyone has the right to burn for it. And in the world of numbers, that right begins with being measured by honest rulers — or honoured by honest silence when no ruler yet exists. Vietnamese women's football does not need more invented legends. It needs writers courageous enough to open an empty dataset, look at it, and say: I will not fill it with lies.
