The Power of Data in Vietnamese Sports

Hook

When the ball rolled at My Dinh National Stadium on a Saturday night, more than thirty thousand fans were cheering. But I was not watching the scoreboard. I was looking at the data control panel in front of me — where every pass, every acceleration, and every tactical decision was being converted into numbers. I have followed Vietnamese football for nearly a decade now, and there is one thing that has always made me uncomfortable: we love football with our hearts, but we manage football with emotion. Everything is changing, but not in the way most fans think.

Context

Vietnamese football is at an important turning point. The V.League is becoming more professional with the participation of major investors, while the national team continues to achieve success in regional competitions. However, from a financial and operational perspective, we are still in the early stages. Vietnamese clubs mainly rely on sponsorship from large corporations, while revenue from broadcasting rights, ticket sales, and merchandise still accounts for a very small proportion. This creates a serious imbalance: when the main sponsor withdraws, the entire system can collapse. We have witnessed this too many times — a team wins the championship one season, and the next season stands on the brink of bankruptcy because it lost its sponsor.

The problem is not that we lack passion or talent. The problem is that we lack a data system to make decisions. While top European leagues use data to optimize everything from tactics to operational costs, in Vietnam, most decisions are still based on intuition and personal experience. This is not wrong — the intuition of experienced football people is very valuable. But as the market becomes more competitive, as foreign investors begin to eye Southeast Asian football, we cannot rely on intuition alone.

Core

Based on my experience following matches over a decade, I notice a large gap between how we spend money and how we create value. Look at the operating costs of a typical V.League club: most of the budget goes to foreign player salaries and blockbuster contracts, while investment in youth academies, data analysis, and training facilities is often neglected. What is the result? We spend a lot of money on average quality foreign players, while local young talents do not have the right environment to develop. The phrase I always use in my reports: "Numbers never lie, but the people reading the report can." We can read a beautiful financial report from a club, but if we look closely at the cost structure, we will see a serious imbalance.

Data analysis in football is not just about counting goals or passes. It is about understanding how a team creates value — both on and off the pitch. Look at the model that top European clubs are applying. They not only hire data analysts, but they build an entire data ecosystem covering every aspect of the club: from player performance, match tactics, to transfer value and commercial strategy. Their transfer data models overvalue young potential, but they have control mechanisms to mitigate risk — something we do not yet have. Mbappe was not a shock, but the tip of an iceberg that we chose not to see. When a 19-year-old player is valued at 180 million euros after a World Cup, we must ask ourselves: where does this value come from? It comes from expectation, not from actual achievement. And in Vietnamese football, we are making the same mistake — paying for expectation, not for real value.

Let us talk about a specific case. Many V.League clubs spend up to 60-70% of their budget on wages, while the safe level is usually recommended to be below 55%. When the Covid-19 pandemic hit, clubs with high wage-to-revenue ratios were the hardest hit. "The pandemic did not create the crisis, it only exposed what we had painted over." When the stadium was empty, cash flow was the only player still on the pitch. Meanwhile, clubs with healthy financial structures and investment in youth development stood firm.

Statistics from domestic leagues show a clear correlation between investment in youth academies and long-term financial stability. Every dollar invested in an academy can generate three to five times the value compared to spending on a high-salary foreign player contract. But it takes time, and investors usually want immediate results. That is the conflict between short-term enthusiasm and long-term value.

Another issue I notice is the lack of transparency in contracts and transactions. "A low-level contract can hide a high-level scandal." There is not always fraud, but when transparent data is lacking, it is very difficult to assess the true value of a transfer deal. This leads to clubs overpaying for players who do not deserve it, or selling young talents at too low a price. "The value of a player is not in his feet, but in the way he is valued."

We also need to look at physical fitness and sports medicine. Data on injuries, training load, and recovery time are important factors that many Vietnamese clubs have not yet fully exploited. While top teams around the world use GPS and tracking devices to optimize performance and reduce injury risk, in the V.League, this is still very rudimentary. An injured player is not just a professional loss, but a wasted investment.

Contrarian

Now, let us talk about something contrary to popular opinion: increasing the number of teams and expanding the league is not always the right direction. Many people believe that the V.League needs to attract more teams to increase competitiveness and popularize football. But from a financial perspective, expanding too quickly can lead to fragmentation of resources. Instead of focusing investment on broadcasting rights, referee support technologies, and infrastructure, we spread capital too thin across too many teams of uneven quality. While leagues like the Premier League or La Liga maintain a stable number of teams and focus on improving product quality, we are dispersing our strength.

"I do not believe in luck. I believe in numbers that have been verified three times." The truth is, small teams with limited budgets but professional management are often more sustainable in the long run than wealthy teams with chaotic operations. Modern data models show that having one more good player is not as important as optimizing the tactical and physical performance of the entire squad. This sounds counter-intuitive, but the data supports it: teams that maintain tactical and physical stability often achieve better results in the long run than teams that depend on one or two stars.

Another counter-intuitive perspective: focusing too much on achievements in international tournaments like the AFF Cup or SEA Games can harm the sustainable development of domestic football. When the entire system channels all its energy toward short-term goals, we neglect building a long-term foundation. Young players are burned out, and clubs do not have enough time to develop their own strategies.

Takeaway

When the stadium is empty, cash flow is the only player still on the pitch. Football is emotion, but clubs survive on algorithms. If we do not start building a transparent and scientific data system, we will only react to shocks instead of proactively creating stability. The question is: when foreign investors enter the Vietnamese football market, will we be ready with data and systems to negotiate from a position of strength, or will we watch them buy and sell our talents at low prices again? Numbers never lie, but what we choose not to see will always be our weakness. Vietnamese football does not lack passion, but it lacks something more important: an operational system based on real data, where numbers are respected before hearts are heard. And that is the only gap we need to close if we want Vietnamese football to be not just a realm of emotion, but a sustainable industry with numbers that speak.
