The N/A Analysis and the 0-7 Loss to the Netherlands: Vietnamese Women's Football Is Missing the Most Important Thing — Data

People worship the commentary of legends; I see a wrong number. This time, however, every number was stamped “not available.” A nine-page, six-section deep analysis produced only “N/A — insufficient information.” That is not an accident; it is a miniature portrait of Vietnamese women’s football. At the 2026 Women’s World Cup, Vietnam finished with three losses, no goals, 12 conceded and less than 30% possession for much of the tournament. The 0-7 defeat against the Netherlands was not the real problem. The real problem is that Vietnam plays without tactical data. There is no database to measure pressing speed, passing maps or recovery time. Praise for the team’s fighting spirit misses the point. Without data, glory becomes a misunderstanding. Bồ Đào Nha, a first-time World Cup team, scored against the US because they used positional data. Vietnam did not. This article argues that Vietnamese women’s football must invest in data science — not just in warm applause. An empty analysis document, one with no information points, is a warning. The door to the changing room is now open, but without numbers to guide decisions, an open door is still a wall.
