The N/A Report: A Data Lesson for Vietnamese Football

Early this week, I received a football analysis labeled “deep dive” in which every section’s conclusion was reduced to one word: N/A. No coded situations, no expected goals, no transfer figures, no player names. Many people would call that a failed draft. To me, it is a mirror reflecting a disease in sports media: we write too much about things we do not know. In football, N/A is not a coward’s answer. It is the only honest response when evidence is insufficient. An offside call needs multiple slow-motion angles; without them, no verdict should be made. A transfer needs to be checked against release clauses and wage structure; without contracts, saying “the club has completed a deal” is fiction. A tactic needs to be measured through pressing numbers; without PPDA, praise for “beautiful play” is pure emotion. An empty analysis, therefore, is more valuable than a commentary full of guesses. This makes me think about Vietnamese football. V-League has skilled players, emotional matches and a passionate community. But our data foundation is still thin. When a young player performs well, we call him “talented”. When a team loses, we say “they lack mentality”. When a foreign striker scores, we call it “destiny”. Those phrases are not wrong, but they cannot explain why a team wins, why a player declines, or why an expensive signing fails. The report I read this week had nine major sections. All returned N/A. Tactics had no data, finance had no numbers, transfers had no legal detail, the dressing room had no signals. Readers might see it as meaningless. But ask the opposite question: if none of that data has ever been collected, then any conclusion is a fabrication. A harmless-looking sports article can create a polluted ecosystem where rumors replace truth and emotion defeats evidence. Vietnamese football does not lack heart, but it lacks a laboratory. I once wrote that “an empty stadium is the best laboratory for a referee.” Without cheering crowds, referees must rely on observation, on law, on movement data. Likewise, when the media stops using vague praise, they are forced to rely on numbers. A league table can lie, but three seasons of synchronized data will reveal the real pattern. Let us talk about finance. The Vietnamese transfer market is heating up every year, but we still read deals in a qualitative way. People discuss player value through phrases like “record fee” without unpacking contract structure. Yet, as I have pointed out, free-agent signing fees are sometimes more toxic than transfer fees because they bypass core financial fair play supervision. Vietnamese clubs are no exception. Without publishing wage procedures or transparent bonus terms, we will never know what a contract really costs. The N/A report reminds me that when financial figures are missing, every claim about a “blockbuster deal” is just a bubble. The tactical dimension is the same. A domestic coach is criticized for defensive football, but nobody measures how many minutes his team is forced to defend under pressure. A striker is called “unlucky”, but nobody tracks his shots inside the box or the quality of chances he receives. Without data, we praise and criticize based on results. If he scores one week, he is “the best”; if he misses one week, he becomes “the destroyer”. That is how a football nation develops slowly, because false information leads to false decisions from the dressing room to the newsroom. Public-pressure is even worse. When a team loses three straight matches, social media immediately demands a new coach. But if we look at open-play possession, chances created and defensive line spacing, maybe that team is not playing badly at all. They just lack luck in finishing. Conversely, a winning team with low xG and a goalkeeper saving everything is likely to collapse. Data-poor media will praise a team riding luck and criticize a team outperforming its expected numbers. That kind of analytical culture pushes Vietnamese clubs toward short-term results, destroying long-term strategy after one bad cycle. I once made a mistake on live television at the 2026 World Cup. I confidently claimed a handball was intentional, but the law was different. That incident taught me: my mistake on live television is the foundation for a new system. I spent a month logging VAR data from tournament matches and comparing every relevant FIFA law. Since then, I stopped writing certain statements and switched to the model: “if you apply rule X, the conclusion is A; if you apply Y, the conclusion is B.” That approach seems slow and dry, but it makes me less wrong. Vietnamese football needs that kind of “slow but steady” mindset. If we build a national data pool covering minutes played, sprint distance, key passes, and successful duels for every V-League player, we will no longer need to ask “who is the best player?” The question becomes: “which metric does this player contribute to?” If we publish referee data – foul counts, penalty rates, VAR review accuracy – Vietnamese football will have a basis to improve officiating instead of merely blaming referees after every round. I am not saying emotion does not matter. Football is best when fans sing in the stands and players run with total commitment. But for sustained moments of brilliance, we need a truthful information infrastructure. An article that answers “N/A” today to avoid being wrong is better than an article that makes a false claim today for clicks. The penalty law is not for the taker, it is for the one who reads it; football knowledge, too, is not for those who merely shout at goals, but for those who know where the goal came from. The future of Vietnamese football is not in a generational talent or a famous coach. It lies in whether we accept looking at N/A reports, ask why data is missing, and fill that gap with a systematic measurement culture. Then sports articles will no longer be places for reckless judgments, but mirrors of a football nation that knows how to examine itself. The real question is not “which team will win the league next season”, but “are we willing to read an honest report about ourselves”.
