When the Footage Is Not Enough: What VAR Decisions Without Evidence Teach Us

**Câu trả lời cốt lõi**: VAR chỉ can thiệp khi có sai sót rõ ràng và hiển nhiên trong bốn nhóm tình huống: bàn thắng, phạt đền, thẻ đỏ trực tiếp và nhận diện sai cầu thủ. Khi mọi góc máy đều không cho thấy tiếp xúc, quyết định trên sân được giữ nguyên. **Dữ kiện chính**: - Ngày 16 tháng 6 năm 2018: VAR lần đầu xác nhận phạt đền tại World Cup, trận Pháp gặp Úc, phút 55. - Ngày 7 tháng 7 năm 2021: trọng tài Danny Makkelie cho Anh hưởng phạt đền ở phút 104 bán kết Euro. - Ngày 1 tháng 12 năm 2022: bàn của Ao Tanaka được công nhận sau khi dựng lại mặt phẳng biên. - Nghị định thư IFAB giới hạn VAR trong bốn nhóm tình huống được phép can thiệp. - Ngưỡng sai sót rõ ràng và hiển nhiên là phép đánh giá chủ quan của con người. **Nguồn**: Luật thi đấu IFAB 2025/26 và hồ sơ trận bán kết Euro 2020 của UEFA, công bố ngày 8 tháng 7 năm 2021 | Cross-checked: VuaBong.vn **Hỏi đáp liên quan**: Hỏi: VAR có được can thiệp khi không có góc máy nào cho thấy va chạm không?

In the 104th minute at Wembley, on the night of July 7, 2026, Raheem Sterling went down inside the Denmark penalty area. Referee Danny Makkelie stood less than fifteen metres from the contact and pointed to the spot almost immediately. The stadium held its breath in the instant before the whistle. I was sitting in front of a screen in Saigon, twenty years old, hearing that sound as a declaration that from this second onward, one half of the world would always feel robbed of fairness.

I replayed the footage seventeen times. On the seventeenth pass, I posted a line in the Hoi VAR Sai Gon group that I would later pay for: there is not enough evidence to confirm contact. Twenty minutes later, hundreds of comments poured in. I panicked and edited it to "it could be a penalty". When UEFA confirmed the referee's decision had been correct, one member left a line I still remember: "Thought you had a VAR eye, turns out you have a trend-following eye."

That semi-final night, I betrayed my own conviction to hold on to my heart.

Context: one law, two readings

VAR was first used to confirm a penalty at a World Cup on June 16, 2026, in France against Australia in Kazan. In the 55th minute, referee Andres Cunha consulted the monitor, confirmed Josh Risdon's handball, and Antoine Griezmann opened the scoring from the spot. I was seventeen that day, a school student in Saigon, staying up all night to write a long analysis of Law 12. The post got forty views. My friends said I wrote like a textbook.

I bring that up because it explains a paradox. Fans do not lack knowledge of the laws. They lack something else: an explanation of why the same incident, under the same law, produces different conclusions in different matches.

The foundational principle of VAR sits in the phrase "clear and obvious error". The IFAB protocol limits intervention to four categories: goals, penalties, direct red cards, and mistaken identity. The crux lies elsewhere. The phrase "clear and obvious" is not a threshold a machine can measure. It is a subjective judgement made by a human being, under time pressure, in front of tens of thousands in the stadium and millions on television.

I still remember an argument in the group about how to translate that phrase. Some translated it as "clear and obvious error", others as "obvious error". The two versions yield two different thresholds. A phrase that can be translated two ways can also be applied two ways.

Even that threshold has exceptions. For offside in a phase leading directly to a goal, the VAR intervenes even when the margin is far smaller than "clear". A match therefore runs on two parallel standards: an arithmetic standard for offside, and a judgement standard for contact.

What the main camera does not see

My early work was tied to incidents the camera angles left behind. In April 2026, when global football was suspended, I started the Hoi VAR Sai Gon group. Each week I took one incident, cut the video, and asked members to choose "penalty" or "no penalty". The Ho Chi Minh City versus Ha Noi match on matchday 12 of V-League 2026 was one of the cases I rebuilt most often, only to find that two consecutive frames can tell two different stories. After three months, the group had five thousand members. Five thousand members, one old monitor, and a belief split into five thousand pieces.

Cutting frames taught me three things a distant spectator never sees.

First, frame rate decides the truth. A contact lasting about four hundredths of a second can fall neatly between two frames at twenty-five frames per second. In that case no frame records the actual moment of contact. Cameras do not lie, but they do not tell the whole story either.

Second, camera angles reconstruct space. A flat frame only means something once you rebuild its position in three dimensions. On the night of December 1, 2026, in Japan against Spain at the World Cup, in the 51st minute, Ao Tanaka scored from a cut-back many believed had gone out of play. I opened frame-cutting software at two in the morning, projected a line along the goal line to rebuild the plane of the touchline, and concluded the ball had stayed in. The post reached twelve thousand interactions within six hours. What I learned was not that I was right. A correct decision can be proven with geometry. A decision short of data cannot be proven with anything at all.

Third, most disputes are not about what the law says, but about whether the event happened. A referee is not handed a fact to judge. He is handed an incomplete dataset and forced to choose.

Those three things add up to a simple consequence: not every incident has a technical truth waiting to be discovered. Some incidents contain only a grey zone, and inside that grey zone people choose according to their own beliefs and then call it a conclusion.

Wrong frame of reference

The most dangerous mistake in analysis is not a wrong conclusion, but a wrong measuring stick. A contact in futsal and a contact on an eleven-a-side pitch do not share a frame of reference. A sparring bout and a performance routine share even less. A routine is scored on difficulty and performance quality, not on a finish rate over opponents. Applying the win-loss logic of professional fighting to a routine produces conclusions that sound highly professional and are entirely wrong.

I have seen the same thing in debates about the V-League. An incident is held up against Premier League standards, and the conclusion follows that Vietnamese referees are weak. That comparison ignores three variables: match tempo, pitch quality, and the number of camera angles. For the same contact, in a match with eight angles, the referee can determine things down to the frame. In a match with three angles, he can only determine things to the level of "possibly".

The paradox of the person without evidence

In data analysis there is a principle known as null handling. When the input is empty, the only correct output is a declaration that no conclusion exists. An analyst is not permitted to fill the gap with speculation, because speculation takes the shape of a conclusion and gets consumed as one. That mistake does not correct itself. It only spreads.

A VAR referee lives inside the same paradox. When every angle fails to show contact, the correct ruling is not a ruling based on feeling, but the on-field decision standing. Not enough evidence to overturn does not mean there was no foul. It only means the imaging system has reached its limit.

This is where fans and referees part ways. Fans grade by a sense of fairness. Referees grade by degree of certainty. The two scales do not share a unit, and no formula converts them. What is worrying is not that the scales differ. What is worrying is when each side believes the other is deliberately choosing the wrong unit.

The counter-intuitive angle: pressure does not come from mistakes

A common misunderstanding of VAR is that technology removes the human element. The opposite is true. Technology does not erase judgement; it compresses judgement into a small room, in front of one screen, over a shorter period, with fewer witnesses. Responsibility does not shrink. It concentrates.

In my group there was once a debate that ran for weeks over an incident on which twelve thousand members split almost exactly in half. What I realised is that most people did not want to know what had happened. They wanted a clear answer. Human beings tolerate ambiguity less well than they tolerate injustice, even though the two usually travel together.

The counter-intuitive point sits here: the greatest pressure on a referee does not come from a wrong decision, but from a right one that cannot be explained within thirty seconds. A referee can live with a mistake. He struggles to live with a community convinced it has been cheated.

The same holds for an analytical system. When an analysis with an empty input still produces a conclusion, the damage is not that the conclusion is wrong. The damage is the precedent: the gap is now permitted to be filled. Next time, nobody can tell analysis apart from speculation dressed in numbers.

Takeaway

Three proposals, ordered by rising cost. Publish the audio between the on-field referee and the VAR room, as some competitions already do; the cost is near zero, the value near everything. Increase camera counts in domestic leagues, particularly behind-goal and high-speed cameras, because most disputed incidents happen in the box. Standardise the publication of reasons when VAR concludes there is insufficient evidence to intervene; silence is the only thing that cannot be defended.

I see what nobody else sees, and I have to live with it. The referee blows the whistle, but the fans are the final graders. If another night like Wembley comes, I will still write that hard-to-hear conclusion, except this time I will attach screenshots of every frame and the coordinates of every contact point. And I will place at the end of the piece, rather than at the start, the line that took me a year to learn how to write: analysis, not a final verdict.
