The Data Gap in Vietnamese Women's Football

In July 2026, in Dunedin, I sat in the stands at Forsyth Barr with a notebook and not a single data screen. Vietnam's women's team had just lost 0-7 to the Netherlands, closing their first World Cup group stage in history with three defeats, 12 goals conceded and none scored. Behind me, a group of fans in red shirts kept singing. I recorded every phase by hand, because the organisers' statistics board offered only a handful of basic metrics: possession, shots, corners. No expected goals. No pressing metric. No touch map. And so nothing on earth could prove how many kilometres Huynh Nhu had run in the first half, or how many passes the Vietnamese back line had absorbed before committing their first foul. In the men's national league, nearly every V.League 1 club has GPS vests, a data provider and a pre-match analysis meeting built on pre-cut video. In the women's league, most matches are not televised, not fully recorded, and nobody collects event data minute by minute. The teams of Ho Chi Minh City I, Hanoi I, Than Khoang San Vietnam, Phong Phu Ha Nam, TNG Thai Nguyen and Son La begin the season with one head coach, one assistant and a notebook. I have sat in many such stadiums. On some days, they did not even have a correct team sheet to hand to the press. The 2026 WK League season in Korea is where I learned to read women's football data. I tracked Incheon Hyundai Steel Red Angels for six months. A substitute forward named Choi Yu-ri had played only 214 minutes, yet her expected goals figure was 3.2, the highest in the squad. I wrote about her, and a month later she started the final match, scored twice and the team won the title. From numbers, I see a person waiting to be called by name. In Vietnam, such people certainly exist. It is just that nobody records their numbers. The problem is not technical. Vietnam's women won the 31st SEA Games at home in 2026 and the 32nd SEA Games in Cambodia in 2026, beating Myanmar 2-0 in the final. To reach the 2026 World Cup, coach Mai Duc Chung's side came through the AFC Women's Asian Cup 2026 play-off in India with wins over Thailand and Chinese Taipei. That is the record of a well-organised football nation. But results and data are two different stories. The pressing metric is the clearest example. PPDA, the number of passes an opponent is allowed before each defensive action by your team, says a great deal about how a side chooses to live. At the 2026 Women's World Cup, Vietnam sat in the low-block group. Three matches and 12 goals conceded was a predictable consequence of facing the United States, Portugal and the Netherlands in the same group. But to know whether the low block came from a lack of fitness, respect for the opponent, or a calculated plan, you need half-by-half data. I do not have it. Nobody published it. Meanwhile, in Europe, women's leagues already have their own data providers. England's WSL, France's D1 Feminine and Spain's Liga F all publish detailed numbers after every match. When Huynh Nhu joined Lank FC in Portugal in 2026, she became the first Vietnamese woman to play professionally abroad. Her passes, her shots, her ball recoveries there were all counted. The irony is that the domestic game where she grew up counts nothing at all. Names are data too. Get a name wrong once, remember it for life; get it right and you value it more. In 2026, commentating at the FIFA U-20 Women's World Cup in France, I mispronounced the name of an England forward three times in the first half. For two weeks afterwards I sat through the footage and learned the phonetics of all 352 players at the tournament. I built a notebook of pronunciations, shirt numbers and biographies covering more than 300 women's players from 16 countries. That lesson has stayed with me: if you cannot even get her name right, do not talk about analysing whether she is any good. The data gap in Vietnam produces three concrete consequences. Good players stay invisible, because a midfielder brilliant at running off the ball, or a defender who reads situations quickly, leaves no trace in any table, and so gets no chance abroad. Coaches are judged on instinct, because without numbers every selection argument ends in personal authority rather than evidence. And sponsors have nothing to sell, because sponsorship of women's football usually rests on image, and image needs stories, and stories need numbers. One detail still troubles me. During the pandemic, when every competition stopped, I lay still in my Incheon apartment for three weeks without writing a line. One evening I video-called Ji So-yun, the midfielder who played for Chelsea. She told me that at 14 she had left her family to train alone. That call in the middle of the pandemic taught me that sport heals without an audience. But it needs people to remember that women players also had childhoods, tears, and years nobody counted. Defenders of the old way will object. They say money should go to players' wages, to pitches, to medical care, not to analysis software. I understand that argument and I do not deny it. But money for data does not compete with money for wages. A 14-round women's league, with event data collected at every match, costs less than a fraction of what a mid-table men's club spends on foreign signings. The issue lies elsewhere: people still treat women's football as a social activity that deserves encouragement rather than a sports product that deserves measurement. Encouragement needs praise. Measurement needs rigour. And rigour is the highest form of respect. If I analyse a Vietnamese women's midfielder and praise only her spirit, I have reduced her to a symbol. If I point out that she passes well on the left but loses the ball too often when pressed centrally, I am treating her as a footballer in the proper sense. The standard must be identical for men's and women's football. The greatest respect is fair criticism, without leniency for gender. The annual season is running. Somewhere in a stadium without cameras, a 19-year-old Vietnamese woman has just run 11 kilometres and nobody recorded it. At 50, I understand that the pitch has no borders, but the heart has coordinates. Mine are in empty stands. If the organisers would fund a single training session for an event-data collector, the next one might not have to wait eight years to be called by name.
