Vietnamese Football: When Data Sources Are Empty and Questions About the Future of Sports Analysis

In modern football, where data and statistics play an increasingly crucial role in shaping tactics and transfer decisions, a concerning reality is emerging: the complete absence of reliable information sources. As sports analysis departments become increasingly professionalized, accessing raw data has become essential, but what happens when that supply is completely empty? This is not a hypothetical question. In reality, many Vietnamese analysts are facing similar situations: a severe lack of in-depth data on domestic leagues, rudimentary player tracking systems, and a significant technological gap compared to top European competitions. This creates a vicious cycle: no data means no in-depth analysis; no in-depth analysis means no improvement in football quality. Take the example of xG (Expected Goals) - one of the most important analytical tools in modern football. While competitions like the Premier League or La Liga have complete xG data collection systems for every possession, the V-League is still in the early stages of digitization. This means Vietnamese analysts lack sufficient historical data to build reliable predictive models, forcing them to rely on international sources or inaccurate estimation methods. Similarly, metrics like PPDA (Passes Per Defensive Action) - a measure of pressing intensity - or GPS tracking (player position and fitness monitoring) are virtually non-existent in Vietnamese football context. Without these tools, evaluating a coach's tactical effectiveness or comparing players' abilities becomes extremely difficult, if not impossible. This situation raises questions about the role of analysts in Vietnamese football system. When there's no data to analyze, does their work still make sense? Or must they shift towards qualitative strategic consulting roles, based on observation and experience rather than numerical evidence? Some experts argue this is precisely an opportunity to build a data infrastructure from scratch, applying the most advanced methods and technologies instead of having to reform outdated systems. The idea of creating a complete Vietnamese football data ecosystem, from grassroots to professional level, is being actively discussed among professionals. However, the biggest challenge remains financial and human resources. Implementing modern data collection systems requires substantial investment, while Vietnamese football is still struggling with more fundamental issues like stadium infrastructure, youth development, and professional management. The question is: Are clubs and the Vietnam Football Federation ready to prioritize technology investment when basic needs are not yet fully met? Another perspective suggests the issue lies not only in technology but also in data work culture. While Western competitions have long traditions in sports statistics, Vietnamese football still maintains a traditional approach, relying heavily on coaches' intuition and experience rather than quantitative evidence. This change requires not only material investment but also a mindset shift at every level of the system. Looking ahead, many experts predict that Vietnamese football will gradually move towards adopting advanced data analytics tools, though this process will be slow and uneven. Major clubs like Hanoi FC, Viettel, or HCMC FC may lead this trend, while smaller teams will face an increasingly large gap in analytical capabilities. It's worth noting that even when current data sources are limited, the role of sports analysts is not diminished. They can take the lead in collecting and systematizing data, building methodologies suited to Vietnamese football's actual conditions, and training the next generation of specialists. This is foundational work with decisive significance for long-term industry development. In conclusion, the data shortage in Vietnamese football is not a disaster but a reality that needs to be acknowledged and solved systematically. With continued technology development and growing investor interest, hope remains that Vietnamese analysts will soon have sufficient tools to perform their work professionally and effectively, contributing to the overall development of the nation's football. This story about data absence also serves as evidence for a broader reality: in an era where information is considered the oil of the 21st century, building data collection and exploitation systems is not only a technical need but also a national competitive strategy in sports. Vietnamese football has much work ahead, but with proper determination and investment, the path forward is entirely feasible. One notable point is that in the context of globalization, Vietnamese football doesn't need to start from zero. Lessons can be learned from successes and failures of preceding competitions, applying experiences appropriate to local conditions, thereby shortening development time. What matters is proactiveness in approaching knowledge and technology, rather than waiting for ideal conditions. In the next decade, Vietnamese football will face many major challenges, from increasingly fierce regional competition to elevated professional quality requirements. Building a solid data foundation will be an integral part of the overall development strategy. And then, the story of a Vietnamese football industry based on data and science will no longer be a distant dream.
