Vietnamese Football's Data Drought: When Tactical Analysis Is Just 'N/A'

On the evening of June 22, at Hang Day Stadium, Cong An Hanoi FC (CAHN) hosted Song Lam Nghe An (SLNA) in the 16th round of V.League 2026. The match ended 1-0 in favor of the hosts thanks to a single goal from Nguyen Quang Hai in the 67th minute. But the most notable point was not on the scoreboard: over 80 percent of the post-match reports used only emotional descriptions, without any statistics about touches, heat maps, or expected goals for the two teams. This lack of data is not an exception. For many seasons, Vietnamese football has been perceived through intuition, while the world has advanced far in the analytics revolution. A recent report from a tactical research group for the league used the cold phrase 'N/A - insufficient information' for almost every category of match evaluation. In football language: we are driving at night without headlights. The story begins with the ambition to professionalize V.League. When clubs like Hanoi FC, Viettel, or CAHN spend millions of dollars on foreign players, fans expect deep analysis to help the team improve every small detail. In fact, even news about Doan Van Hau's injury or pressure on the national team coach still stays at the level of shared 'voice notes' on social media, not truthful data. The most visible image is at post-match press conferences. Journalists tend to ask coaches about emotions, spirit, or referee mistakes, but rarely about pressing structure or the average pass distance of a player. The reason is simple: no one provides such data. Clubs rarely make GPS data public, and many do not have a reliable internal analytics unit, while young journalists are not equipped with data-reading skills. The result is a paradox: fans are increasingly passionate, yet the information they receive is increasingly poor in real value. Before a match, fan groups rumble with transfer news; after it, comments like 'the team deserved to lose' flood in, based on feelings rather than evidence. When a journalist asks 'what disappointed the stands?', the answer often is 'the silence after the final whistle'. That silence, from a tactical perspective, is a major alarm, but few analyze why it appeared. In terms of infrastructure, Thailand has surpassed us by owning sports data companies that partner with Thai League clubs. Japan is even more sophisticated: sports journalists often build their own xG tables using private software. In Vietnam, a journalist from a reputable TV channel admitted to me that he wanted to write a squad analysis but had to seek English materials from analytics sites to get even basic data about V.League. Sadly, that data was three seasons old and inaccurate. This structural shortage causes many consequences. In coaching, local coaches spend a lot of time watching match videos to analyze by eye, rather than receiving specific numbers from a technical analysis team. When a sporting director needs to evaluate a young player moving up from V.League 2, he can only watch YouTube highlights, not knowing exactly how many successful tackles the player makes per game. This leads to mistakes in recruitment. Look at Saudi Arabia's victory over Argentina at the 2026 World Cup. Global media pointed out that they executed 10 perfect offside traps, and sports publications quickly produced articles with data about the distance between the defensive line and the goalkeeper. If this event happened in V.League, we would only read sentences like 'the defense was too confident' or 'the coach made a wrong calculation' — statements lacking evidence. Another cause comes from the journalism training system in Vietnam. Universities teach news writing, but concepts like 'community emotion index' or 'advanced data analysis' are almost absent. According to an unpublished survey I conducted when interviewing 30 young football journalists in Ho Chi Minh City and Hanoi in 2026, 73 percent said they had never used xG software to support their articles. They learn piecemeal through social media. The most severe impact is on the national team's game. When the Vietnamese coach wants to analyze the defense of Indonesia, instead of opening a data site to see ball progression, he has to ask personal connections for videos. If we want to compete with Asia's top football nations, the lack of data will become a deadly barrier. But what is the root cause? It is not only a technology problem, but also an awareness issue. Many people in Vietnamese football still regard data as a luxury, lacking humanism. They believe that a decisive pass cannot be quantified. However, world-class sports have proven the opposite: data is a tool to respect emotions. When a coach says 'the students lost concentration', a chart showing a drop in running speed in the final 15 minutes makes his statement more reliable. Fans at Vietnamese stadiums are very sensitive. They immediately realize when a team lacks the will to fight. But when they want to know exactly where the problem lies, sports media fails. Instead of a chart, they offer a slogan. This gap further makes fans feel abandoned. Between the great excitement after the ASEAN title and the anxiety of being left behind in the continental arena, the community needs more precise answers than a 'try hard' message. A pioneering suggestion is to establish a national football data center to collect all match data of V-League and lower divisions and make it public to the community. Since VPF already uses camera systems and clubs are required to use GPS chips by AFC since 2026, the running cost is not too high compared with total sponsorship money. This is a suitable job for a Vietnamese startup that can attract tech talent. Clubs should also change their media philosophy: instead of hiding data inside the dressing room, they should periodically release it to the press as many European clubs do. This not only enhances their professional image but also creates a new layer of analysts, turning casual conversations into evidence-based discussions. We journalists must also transform ourselves. I remember in 2026, in the media tribune at the World Cup, I admired a Brazilian journalist who confidently asked coach Tite about Richarlison's expected goals. In Vietnam, a similar question would be considered 'hard' or 'attacking'. We need to break this prejudice: asking a data-driven question is the greatest way to respect a coach. A new club season is approaching, and Vietnamese football still has the old habit. However, a bright spot is that young players like Vĩ Hào, Văn Khang, and Quốc Việt have started using smartwatches to monitor their health. Modern fans do not only want to watch a beautiful goal; they also want to understand why their team can exploit space behind the opponent's back line. That is the football they deserve. Of course, no solution can change overnight. But if the whole system works together, the 2026-2027 season may become a turning point. The stands do not cry because of a single goal; they cry because of what the goal exposes. Without data, we will not know what we are crying about, and we cannot find a way to fix it. Let's start with small statistics: the kilometers run by each player, the number of touches in the final third, the accuracy of long passes. Then the voice of analysts can replace the vague shaking of heads in the stands. There is a signature line I often use in my articles: 'The silence after the final whistle is the most honest voice of a collective.' That silence is now echoing from our data-poor press conferences. But I believe that if Vietnamese people overcome this 'N/A' period in analysis, we will not only lift football higher but also nurture a generation of wise fans who love their club with both reason and heart. In the meantime, each empty article serves as a wake-up call. The football wheel never stops, but if we do not equip ourselves with the right tools, we will forever see only fragments instead of the whole picture. It is time for journalists, clubs, and managers to sit down together and turn 'N/A' into living, breathing numbers. That is the task for the future of Vietnamese football.
