Minute 73 at Anfield, February 2026. Sadio Mane received the ball in a position the naked eye could not resolve from the stands. The assistant referee's flag stayed down. The ball ended up in the net, Liverpool levelled at 1-1, and Sunderland dropped two points in a way no manager can formally appeal — because the replay only rolls after the whistle has dissolved into the crowd.
I was sitting high on the touchline side, notebook open, marking the 31st decision of the match. Few people leaving Anfield that afternoon knew this passage of play would become the first data point in a tracking sheet I would keep for years afterwards.

Context: the last seasons of the human eye
Mike Dean walked into that match with more than 500 Premier League appearances, among the most experienced referees in the competition's history at that point. Sunderland led from the first half, Liverpool pushed forward, and Anfield braced for a long afternoon. Jermain Defoe was the man who put the visitors ahead — the kind of striker who needs half a chance.
One thing must be stated plainly: 2026-17 was among the last seasons in which the Premier League ran entirely on human observation. Goal-line technology had only arrived in 2026-14, and it answered a single question: had the ball crossed the line. Every offside, every collision and every penalty appeal remained entirely in the hands of the officiating team. Video assistance trials were still embryonic at continental level and had not reached England.
In other words, at minute 73 that afternoon, no camera had the authority to intervene.
Core: 47 decisions, 12 criteria, one error
After the match I reconstructed the game and logged 47 decisions by the officiating team — clear fouls, advantages played, card management, and the passages allowed to run that spectators rarely register. Drawing on my experience of watching matches at Anfield and across Premier League grounds, each decision was scored against 12 criteria: position, viewing angle, distance to the point of contact, reaction time, and consistency with similar incidents earlier in the same match.
The result: Mike Dean was wrong once. An accuracy rate of 46 out of 47.
That single error fell on an offside decision — and not by chance. Of the 47 decisions, 12 concerned offside, and this is statistically the highest-risk category in the entire system. The reason is physical rather than attitudinal: an assistant referee must hold two reference points inside a single field of view — the ball and the last defender — while the ball travels above 25 km/h in fast counter-attacks and the practical judgement window sits under 200 milliseconds. Add the rake of the Anfield stands and the distance to the touchline, and the viewing angle narrows further compared with the ideal surface drawn up in training.
A referee can be wrong on 2.1 percent of decisions and still take 100 percent of a club's points — that is football's risk structure, not a moral failing of one individual.
I have often sat back after matches like this one to test an uncomfortable question: if the error rate sits inside an acceptable band, why does the anger persist? The answer lies in distribution. Random errors scattered across 90 minutes are forgotten. Errors concentrated on the exact moment that produces a goal destroy a week of preparation.
Contrarian angle: the anger is right, the target is wrong
The fury aimed at Mike Dean is an understandable response and a misdirected one. At 46, after years of re-reading matches with a pencil and squared paper, I have learned that referee reports are almost never read correctly, because people only read the errors.
A camera finds the fault; a person finds the cause. An offside missed reflects the limits of human vision, not carelessness. Demanding that a referee should have seen it is an emotional statement with no basis in how a high-speed match is actually officiated.
One further point is rarely mentioned: it is the officiating teams themselves who argue hardest for more tools. Nobody wants to be named on television for a single mistake, especially when a referee's power comes not from the whistle but from the ability to read the situation.
Takeaway
The best referee is the one nobody mentions after the match. But that standard is only fair when mistakes are as silent as they used to be. Once every passage of play can be replayed from eight angles, we have changed the rules of recognition: referees are no longer judged on the whole match, but on their worst moment.
For Sunderland, the two points lost at Anfield in February 2026 translate directly into league position in May. For Liverpool, a point won by an incorrect decision is a point nobody inside the club truly wanted to keep. And for English football, that afternoon sits inside a chain of evidence pointing to a conclusion that had been forming for years: one error in 47 decisions is a good rate, until it lands on minute 73.
