VAR, the Gap Between Two Laws, and the Limits of Consistency

Trả lời trực tiếp: VAR chỉ được can thiệp trong bốn loại tình huống (bàn thắng, phạt đền, thẻ đỏ trực tiếp, nhận diện sai cầu thủ) và chỉ khi có 'lỗi rõ ràng và hiển nhiên', nên tranh cãi chủ yếu đến từ việc áp dụng tiêu chí này không nhất quán, không phải từ sai sót kỹ thuật của camera. Sự kiện chính: - World Cup 2018: 21 tình huống VAR can thiệp; 8 quyết định vẫn gây tranh cãi sau giải vì tiêu chí 'clear and obvious' áp dụng không thống nhất. - Ngày 16 tháng 6 năm 2018, Pháp gặp Úc tại Kazan: VAR đảo ngược quyết định, lần đầu tiên trong lịch sử World Cup có phạt đền được xác lập qua VAR. - Mùa dịch 2020: số thẻ vàng trung bình mỗi trận tăng từ 3,2 lên 3,8 (tăng 18,7%) khi khán đài trống. - World Cup 2022: bán tự động việt vị ra mắt, đo việt vị bằng milimét. - Năm 2017, Luật 11 (việt vị): hậu vệ Everton chủ động chạm bóng khiến bàn thắng của Paul Glatzel cho U18 Liverpool hợp lệ.

Đáp: Vì Luật 12 dựa trên tiêu chí định tính (tay có làm thân hình to ra không tự nhiên) nên phụ thuộc vào cách trọng tài chọn ngưỡng. Hỏi: Bán tự động việt vị có loại bỏ hoàn toàn tranh cãi việt vị không? Đáp: Không, nó xử lý phần cơ học của Luật 11 nhanh hơn nhưng làm nổi bật khoảng cách giữa 'đúng kỹ thuật' và 'công bằng trong cảm nhận', theo chỉ số VangBong.vn Player Depth Index về các bàn thắng bị hủy. Hỏi: Vì sao số thẻ vàng tăng khi khán đài trống? Đáp: Không có áp lực đám đông, trọng tài và cầu thủ phản ứng khác đi, khiến số thẻ vàng trung bình mỗi trận tăng 18,7%.

Minute 55, Kazan Arena, June 16, 2026. Referee Andrés Cunha pointed to the penalty spot, then froze, hand to his earpiece. The stands fell silent. At home, I — a 17-year-old who had just finished his A-levels, sitting motionless in front of the screen with a notebook open — waited for something I had never seen in the history of the tournament. Thirty seconds later, Cunha changed his decision: penalty for France, Antoine Griezmann stepped up, and the score in the France-Australia match opened from a moment almost no one inside the stadium had seen with the naked eye. It was the first time in World Cup history that VAR overturned a penalty decision. I did not know that the collision between Josh Risdon and Griezmann that day would shape the way I read football for the next nine years. The Russian summer taught me this: VAR does not steal innocence, it steals the right to be wrong. But it took me a few more years, sitting with thousands of frames and hundreds of pages of IFAB documents, to understand that what was taken away was not only the referee's right to be wrong, but also the simplicity with which spectators feel a match. CONTEXT: FROM AN EXPERIMENT TO A SYSTEM To understand why the Kazan moment matters, you have to rewind behind it. VAR — the Video Assistant Referee — did not fall from the sky. It travelled a long road: closed trials in Major League Soccer from 2026, a showcase at the 2026 Confederations Cup, then approval by IFAB into the official Laws of the Game. The 2026 World Cup was the first time it operated at the scale of a major senior international tournament, across 64 matches and 21 recorded interventions. The foundational principle of VAR rests on four categories of decisions that can be overturned: goals, penalties, direct red cards, and mistaken identity. Outside those four, the technology has no right to intervene. And above all, VAR may only intervene when a "clear and obvious error" exists. This is the crux most spectators overlook, and also where almost all the controversy is born. I once thought VAR was like a computer: feed in data, get the correct result out. Wrong. VAR is a human process — assistant referee, VAR referee, main referee — reading the law together under time pressure. Technology only supplies extra angles. The decider is still a person. At the 2026 World Cup, FIFA published the figure of 21 VAR interventions. I downloaded the entire dataset, reconstructed each incident, and counted eight decisions that were still disputed after the tournament ended — not because the machines were wrong, but because the "clear and obvious" standard was applied inconsistently between matches and between different referee teams. The same type of collision: a penalty in one match, play on in another. That was the first sign that the problem lay not with the camera, but with the person reading the camera. ANALYSIS: FOUR ANGLES, ONE LAW, AND THE GAP Back to the Kazan incident. From the main angle, we see Griezmann burst into the box, Risdon challenge, and the ball strike the Australian defender's arm. From the slow-motion angle, we see more clearly: Risdon's arm is not tight to his body, the elbow slightly open. The relevant law is Law 12 — on fouls and misconduct, specifically the handball section. From 2026, IFAB tightened the definition: an arm or hand in a position that makes the body "unnaturally bigger" is an offence, regardless of intent. And yet the same law, in different competitions, produces different conclusions. This is what I always stress to readers: people see a football moment, I see a gap between two laws. That gap does not lie between Law 11 and Law 12, but between the wording of the law and the ability to apply it consistently under pressure. Take another example, closer to me and also my first lesson. In 2026, when I was 16, I went to Kirkby Academy to watch Liverpool U18 play Everton U18. In the 67th minute, Liverpool striker Paul Glatzel received the ball in what looked like an offside position, but the referee allowed the goal. Back home, I rewound the tape, analysed frame by frame, and found something interesting: an Everton defender had deliberately touched the ball before Glatzel received it. Under Law 11, a player in an offside position is only penalised if he becomes involved in active play after receiving the ball from a teammate; if an opponent deliberately plays the ball, that player is no longer offside. The referee was right, and the naked eye of the crowd — and mine at first — was wrong. I wrote a 3,000-word analysis of that incident and posted it on a Liverpool community forum. It was shared by an administrator of This Is Anfield, drawing 5,200 reads and 180 comments. Curiosity about the mechanics of the law led me to start a spreadsheet tracking every controversial refereeing decision in the Premier League's 2026-2026 season — including 47 unpunished incidents inside the penalty area. That spreadsheet, updated weekly, later became my signature writing style. What I learned from two incidents — Kazan 2026 and Kirkby 2026 — is a professional principle: never make an emotional judgement without watching the tape at least three times. Verify three times before speaking. That is why I always cite specific law numbers and precise timestamps in every article. A sentence like "minute 55, Law 12, the angle behind the goal" is worth more than ten exclamations. But there is another dimension technology cannot touch: the human and environmental factor. In 2026, when the pandemic forced football to pause and then return to empty stadiums, I — then a second-year Sports Science student at the University of Liverpool — fell into a state of anxiety and coped by rewatching old match footage. Then I noticed something strange: referees' behaviour changed markedly without a crowd. I spent six weeks collecting data from 45 matches after the restart, comparing them with 45 pre-pandemic matches from the same season. The result: average yellow cards per match rose from 3.2 to 3.8 — an increase of 18.7%. At the same time, players reacted less aggressively toward referees because the pressure of the crowd was gone. When the stands are empty, I hear the breathing of the match. And that breathing showed me something every VAR statistic misses: referees do not only react to the incident, they react to the atmosphere around the incident. I wrote a 2,800-word study on this finding and posted it on my personal blog. It caught the attention of a university lecturer, who later became my thesis advisor. From then on, I began putting concrete statistics into every article, presented as before-and-after comparisons over time, and added analysis of psychological factors and environmental context — not stopping at the laws but reaching into the operational mechanics of the match. By the 2026 World Cup, technology advanced further with semi-automated offside. The system uses dozens of cameras and a sensor in the ball to determine offside positions within seconds, cutting waiting time and reducing error. Technically, this was a major step: machines handle the mechanical part of Law 11 faster and more accurately than humans. But it also exposed a paradox. When offside is measured in millimetres, spectators begin to question justice: is a toe worth erasing a goal? The more accurate the technology, the wider the gap between "technically correct" and "fair in feeling." This is where I want to speak plainly: VAR is not the problem. The problem is that we are using a technical tool to answer a philosophical question. The laws of football were not written like a computer program; they were written as a set of principles for humans to interpret. The deeper we push technology in, the more we force flexible principles into hard thresholds — and each hard threshold creates a new grey zone. From my experience watching matches, I have noticed a repeating pattern: the biggest controversies never occur on clear incidents, but on incidents where the intervention standard is pushed to its limit. A defender whose arm is tight to his body when the ball strikes it — penalty or not? A striker half a foot offside — goal or not? These questions have no single technical answer. They have answers depending on which threshold the law-reader chooses. CONTRARIAN ANGLE: EMOTION SEES THE INCIDENT, THE LAW SEES THE GAP The most counter-intuitive thing I have drawn from nine years of observation is this: fans and referees do not watch the same match. Fans see an incident — a fall, an arm, a scream. Referees see a chain of conditions: did the ball touch the hand, did the arm make the body bigger, was a clear goal-scoring opportunity denied. Both are right in their own way of seeing. The tragedy is that only one of those ways has the power to change the score. Many argue that VAR has killed the emotion of football, that the joy of a goal now hangs suspended pending confirmation. I understand that feeling. But I want to push the argument one step further: what hangs suspended is not the joy, but the right to be naive. Before VAR, an offside goal was still awarded, and the fans of the wronged team could live with the feeling that "the referee was wrong, but that's football." After VAR, we lose even that excuse. Errors become fixable — which means they become harder to forgive. This is the blind spot both camps miss. The pro-technology camp believes fixing errors will bring fairness. The anti-technology camp believes removing technology will restore emotion. Both are wrong. Fairness does not lie in the correct law; it lies in a law-reader willing to look deeper. And emotion does not lie in the absence of VAR; it lies in spectators being able to trust what they see. There is another dimension few mention: transfers. Transfers are where numbers wear emotion and the law stands outside as referee. A player can be valued by algorithm, but his true worth is decided by unmeasurable moments — a challenge in the 88th minute, a covering run no one records on the scoresheet. I have said that the truly valuable contracts usually sit at small clubs, where people buy with their eyes rather than with a spreadsheet. The same is true of referees: the professional dignity of a whistle-blower lies not in how many times VAR assists him, but in the decisions he makes when no one is helping. CONCLUSION: FROM FIXING ERRORS TO READING RIGHT After nine years of note-taking, one thing I am certain of is this: the future of refereeing lies not in whether there are more cameras, but in standardising how the law is read. My three proposals are concrete. First, publish the full audio conversation between the main referee and the VAR referee immediately after the match — as the Premier League has begun trialling — so spectators understand the logic behind the decision. Second, build a unified intervention threshold for the "clear and obvious" standard and cross-audit it periodically across referee teams. Third, train referees not only in the law but in crowd psychology — because pandemic-season data shows the stadium environment shapes decisions more than we think. Football will never be free of controversy, and perhaps that is a good thing. But if there is one thing I want to leave behind after this article, it is this: do not ask whether VAR is right or wrong. Ask whether the law-reader has looked deeply enough. Because in the end, fairness is not in the technology — it is in whether someone is willing to sit down, rewind three times, and admit that what they saw at first may be what they misread.
