Vietnamese Sports Industry: From Spending to Profit - Lessons from Valuation Mistakes

When the stadium is empty, I can hear the sound of every budget dollar. This statement has never been truer for the current Vietnamese sports landscape, where clubs are racing to spend while forgetting that the market does not forgive, it only records — and I paid the price in the 2026-18 season. The current context of Vietnamese football is witnessing a strong wave of investment from major corporations. Clubs like CAHN, Thép Xanh Nam Định, and Becamex Bình Dương are spending tens of billions of đồng on high-quality foreign and domestic players. However, the question is not how much they spend, but how they spend it and whether those investments generate returns. I learned valuation from one mistake, and never needed a second lesson. In 2026, I proposed spending 12 million euros on midfielder Jonathan Viera at Beijing Guoan, based on key pass and expected assist data from La Liga. I overlooked the adaptation factor to the Chinese football environment, leading to a decline in form after just 6 months. The management had to sell him for 8 million euros, a loss of 4 million. That lesson taught me that data cannot replace direct observation. Applying that lesson to the Vietnamese market, I notice a concerning pattern. Many clubs are spending money based on player reputation rather than fit with the tactical system. Look at the Rafaelson deal at Thép Xanh Nam Định — a smart valuation decision based on field data, not reputation. This player scored 31 goals in V-League 2026-24, a number that accurately reflects his true value in the Vietnamese football environment. A tight budget does not create poverty, it creates sharpness. Vietnamese clubs need to learn how to optimize costs rather than engage in an arms race. During the COVID-19 crisis in 2026, I proposed a plan to cut 35% of unnecessary operating costs at Shanghai SIPG, saving the club 2.3 million RMB in Q2 — enough to retain two Brazilian assistant coaches. That is clear evidence that smart financial management matters more than having more money. Spinazzola does not take free kicks, he imprints a new valuation rule. At Euro 2026, I discovered that this wing-back had 10 successful crosses into the box in the first 4 matches, while same-tier wingers averaged only 5. I proposed a transfer valuation formula based on xT from the left flank for 5 top Premier League clubs. This lesson applies directly to Vietnamese football: find undervalued roles in the squad rather than chasing expensive names. The Vietnamese transfer market has a fundamental problem: player agents are the biggest hidden cost. The noise they create distorts the market. Many deals are inflated by media and agents, causing clubs to pay more than actual value. I have witnessed this many times in my career — players overvalued because of a few good matches, while players who truly fit the system are overlooked. Look at the Julian Alvarez failure at Manchester City — I once concluded high risk because South American form means nothing. Result: Manchester City signed him and in 2026-23, Alvarez scored 17 goals in the Premier League. I was wrong. But from this mistake, I was forced to rebuild my player evaluation method by adding weight to live-ball situations and space-creation ability rather than just looking at raw statistics. Vietnamese football is at a critical crossroads. Clubs can continue to spend recklessly based on reputation, or they can build a smart valuation system based on field data. The answer lies in whether they are willing to change their mindset. I have seen many Asian clubs fail because they refuse to learn from their mistakes. The problem is not how much money you have, but how you use it. A club with a 50 billion đồng budget but smart management can beat a club with a 200 billion đồng budget but poor management. This has been proven many times in world football history, and Vietnam is no exception. Vietnamese clubs need to build data-driven scouting systems, not just gut feeling. They need to invest in tactical and physical analysis, not just buying expensive players. They need to understand that a player who fits the system is more valuable than a good player who does not fit. I have followed Vietnamese football since the early days of V-League, and I see enormous potential. But that potential will be wasted if clubs do not change their approach. The market does not forgive valuation mistakes, and clubs that do not learn this lesson will pay a heavy price. The final question is not whether Vietnamese clubs have enough money, but whether they are smart enough to use that money effectively. When the stadium is empty, I hear the sound of every budget dollar — and I believe that clubs that know how to listen will be the winners in the long run.
