Empty Analysis Report: A Wake-Up Call for Vietnamese Football

When I received the document 'Stage-2 Deep Analysis' from a colleague, I thought I was seeing things. The entire report – from tactical analysis to financial control – was marked 'N/A' or 'no information'. A deep analysis completely empty. But instead of discarding it, I saw it as a perfect metaphor for Vietnamese football today: where people talk a lot about development, but there is no data foundation to prove it. In modern football, top clubs around the world use hundreds of metrics – from xG, PPDA to sprint counts. They build transfer strategies based on predictive models, assess players using sensor data, and even optimize training schedules with algorithms. But in Vietnam, for many teams, having a complete statistical record of successful passes is still alien. People still judge by feeling, by a few YouTube highlights, by rumors among scouts. Look at the V-League itself. Try to find an in-depth tactical article analyzing the difference between high and mid-block pressing of a Vietnamese team. You will see they are extremely rare. Instead, there are colorful articles about fighting spirit, about 'warrior hearts' – phrases that cannot be verified. Yes, football has emotion, but that emotion should be placed on a foundation of numbers to avoid self-deception. That is why an 'in-depth analysis' report that is empty is valuable. It exposes an uncomfortable truth: many sports journalists still write in a 'guessing' manner, based on unverified sources, and are lazy in delving into tactics. They prefer meaningless arguments on social media over sitting down to rewatch tapes to point out a defender’s wrong position. But please do not misunderstand. I am not saying that data is everything. Tactical masters like Arrigo Sacchi – who never watched data – still created one of the greatest teams in AC Milan’s history. However, Sacchi was a rare genius with extraordinary eyes. For mediocrities like me and other analysts, data is a staff to lean on when walking in the woods. It doesn't help you see the rare tree, but it helps you not stumble too much. In last year’s speech at a sports forum (which I attended), an expert said: 'We have too many opinions and too few facts.' I could not agree more. Look at how young Vietnamese teams have recently been assessed. Most comments rely on a few friendlies, while lacking any database on player development. In Japan – where I was born – they have had a national data system for decades. The result is a football culture that continuously produces talents able to compete in Europe. I still remember the moment in 2026 when I wrote the article predicting Quang Nam would win the V-League. At that time, I relied not only on intuition. I watched every single match, recorded their strengths and weaknesses, and compared them with opponents. I used raw data from league tables that I had created myself. And the result came: Quang Nam won, and I was hailed as a 'prediction prophet'. But I knew that without data preparation, I was just a lucky man. The Germans won the 2026 World Cup through analyzing data from thousands of matches to detect trends. They also suffered a painful defeat at the 2026 World Cup when they ignored warning signals from data showing their style had been figured out. Vietnamese football does not need to copy Germany, but we need to start building our own data reservoir. This requires coordination across clubs, federations, and media. An empty report may seem like a failure, but it is actually a mirror reflecting a systemic deficiency. Let us treat it as a test: if you read a sports analysis article and see no numbers, it is time to raise questions. For those of us in the media, it is time to abandon the habit of writing like a school essay and start digging into data to give audiences what they deserve. Football is not a sport of illusions. It is a sport of passes, shots, and runs that can be counted. Let us start counting them, or accept being left behind. There have been too many empty reports. It is time to fill them with numbers.
