Navigating Vietnamese Football: Data Tactics and the Future

In Vietnamese football, there has long been a time when fans only knew matches through the lens of emotion and enthusiasm. However, as the football world shifts into the data era, Vietnamese fans are also beginning to see that numbers and statistics are not just dry figures but stories behind each match. In this article, we will deeply analyze the data-driven approach in Vietnamese football, from metrics like xG (expected goals), PPDA (passes allowed per defensive action) to the role of coaches and players in applying these new methods. First, let's talk about xG. This is a crucial metric that data analysts use to assess the quality of goal-scoring chances. In Vietnamese football, xG is gradually becoming an indispensable tool in evaluating team performance. But interestingly, not everyone understands xG well. Many still think that a team creating more chances will have a higher xG, but in reality, xG depends on the quality of chances, not the quantity. For example, a shot from distance has a much lower xG than a shot inside the box. This means Vietnamese teams need to change their approach to creating chances, not just shooting more but shooting smarter. Next, PPDA is another important metric. PPDA measures the pressing intensity of a team. When a team has a low PPDA, it means they allow the opponent to pass the ball many times before making a defensive action. Conversely, a high PPDA indicates a stronger pressing team. In Vietnamese football, many teams still lack understanding of PPDA and how to apply it tactically. This creates a gap in tactical development, making it difficult for teams to cope with stronger opponents. However, not only statistical metrics matter. The role of the coach is also crucial in applying these methods. A data-minded coach will know how to use these metrics to improve team performance, but they also need to know how to combine them with the emotional and spiritual factors of players. This creates a balance between science and art in football. A typical example is the use of GPS to monitor player health and performance. In Vietnamese football, GPS is gradually becoming an important tool in managing player fitness. But not every team has the resources to invest in this technology. This creates a gap between big and small teams, making it difficult for smaller teams to compete. However, nothing is impossible. With technological advancement, smaller teams can also apply these methods if they have enough determination and resources. What matters is that they need to have a new mindset, not afraid to change, and always seek improvement. Speaking of the future, Vietnamese football is facing a great opportunity to develop in a data-driven direction. But to achieve this, investment is needed from both clubs and the football federation. They need to create a favorable environment for data development, while also encouraging coaches and players to adopt these new methods. One of the biggest challenges is changing the mindset of fans. Many fans are still accustomed to watching football through an emotional lens and do not understand statistical metrics. This makes applying data to football more difficult, as fans may not agree with data-driven decisions. However, with the growth of social media and media platforms, fans are gradually accessing this information. This creates an opportunity to educate fans about the importance of data in football. Overall, Vietnamese football is at a crucial turning point. Applying data to football not only improves team performance but also helps fans understand the game better. But to achieve this, close cooperation between clubs, the football federation, and fans is needed. With what is happening, I believe Vietnamese football will have a brighter future in applying data. And I hope that in the near future, we will see many Vietnamese teams using data to create unexpected victories, similar to what has happened in major tournaments around the world.
