2:14 a.m., a night in mid-July. The phone on the desk buzzed twice and went quiet. The screen lit up with a screenshot: a club crest, a player's name, a fee expressed in millions of euros, and three exclamation marks lined up side by side. No headline. No source. No date. The sender was an acquaintance in Seoul, with exactly one line attached: "Heard it's done."
I turned the phone face down, opened the second drawer, and took out a leather notebook faded at the spine. The first page I still have is dated 12 May 2026: Busan Daewoo Royals against Lucky-Goldstar Hwangso in the K-League, final score 1-1. In the margins are small, cramped lines written quickly in blue ink — misplaced passes per player, minutes of dead ball, successful tackles, estimated running distance for both centre-backs. Not one sentence of commentary. Not one adjective.
Five years later, in November 2026, my club stood one match away from relegation, in a play-off against Ilhwa Chunma. Three days before kick-off, a rumour spread through the training-ground corridors: two senior players had fallen out, the dressing room was split. The rumour carried enough detail to look real — a time, a place, even the role of a person said to have witnessed it. I did not publish. I asked. Three days, three rounds: a club staff member, an assistant coach, and a substitute player who agreed to talk on condition that neither his name nor his position was used. The result: the rumour traced back to an ordinary, tense training session in which two players raised their voices over a challenge and shook hands afterwards. In the play-off, my club won 2-0 and stayed up.
Since then I have held an unwritten rule, and I have kept it for more than thirty-five years: never publish anything that has not passed two independent sources. On sensitive stories, I refuse the phrase "a source close to the situation" unless I can describe exactly where that person sits inside the club's structure.
Forty years after I opened that first notebook, the transfer market has become something else entirely. Not because people became worse. Because the speed, volume and packaging of information changed to the point where a false report can look better dressed than a true one.
The ball does not lie, but the person holding the pen can.
The transfer window runs like a market with two commodities. The first is players. The second is information about players. The second trades more heavily, faster, and with almost no body standing by to certify quality.
In Europe the summer window runs for weeks. In Korea, the K League has its own registration periods, usually split between the start of the season and the mid-season break. In Vietnam, V.League 1 keeps a separate rhythm tied to domestic fixtures and youth competitions. Each of those periods opens a gap: fans know change is happening, but have no way to verify which change is real.
Into that gap, thousands of accounts, outlets and personal channels produce content about a finite number of genuine deals. The signal-to-noise ratio therefore drops to its lowest point of the football year. And here is the central point: the loudness of a report does not correlate with its accuracy.
Readers today are not short of information. They are short of a filter. They need to know which item deserves to be remembered, which should be read and forgotten, and which should be treated as though it never existed. That is the job of a sports journalist — not to be fastest, but to build a screening system clear enough that readers can apply it themselves.
Based on my experience tracking matches since 2026, most errors in transfer reporting do not come from a journalist inventing things. They come from a journalist accepting a single source because that source arrived at the moment they needed one.

Player agents are the largest hidden cost in this market and its largest source of noise. An agent has a rational motive to put unverified information into public circulation: to apply pressure on a club mid-negotiation, to raise the bargaining value of a client, or simply to let another club know that their player is being watched. These motives are not crimes. They are simply motives the reader cannot see when reading a two-line item.
At sixty-seven, I no longer care who is faster. I care about a different question: how do you tell a report with content from a report that only has form?
In twenty years travelling with a club, I learned that the most reliable thing on a matchday is not on the scoreboard. It is in details you only see if you stand close enough and long enough. Which player arrives late to training three days running. Which centre-back tapes his left ankle in both the tactical session and the fitness session. Which full-back is pulled aside for ten minutes after training. None of that appears in a press release, but it is better raw data than any rumour.
Numbers tell part of the story; the rest is in the mud on the boots.
In the transfer market, the equivalent of mud on the boots is observable events. A player absent from the squad photograph. A club leaving a player out of its registration list with no injury announcement. A head coach answering a question about a player's future vaguely, while answering every other question clearly. Those traces do not prove a deal is happening. They only narrow the space of what could happen.
That is the first layer of my verification discipline: record only what was observed, not what was recounted.
The second layer is cross-checking. In the 2026 case, I never used the phrase "a source close to the situation." I described exactly who was speaking inside the system — club staff, assistant coach, substitute player — and I stated clearly that they had not watched the same incident from the same position. If three people tell the same story in the same wording, I treat that as a bad sign, not a good one. Three identical accounts may be three copies of one source.
The third layer, and the one most transfer reports skip, is contract context. A transfer fee means nothing without contract length, instalment structure, wage level, and the timing of how the cost sits on the books. A four-year deal on high wages creates an entirely different financial burden from a deal of the same headline value paid in instalments. A release clause can turn an impossible transfer into an administrative procedure, or turn an almost-complete deal into an auction.
That is why I tell younger colleagues in Busan that if all they have is a fee and a name, they are holding a report that is structurally incomplete, before we even discuss content.
I want to describe a phenomenon I see more and more, and I name it with a term borrowed from engineering: silent degradation.
In a data pipeline there is a failure mode more dangerous than an obvious error: the system returns a result that is perfectly valid, correctly formatted, fully populated with fields, yet contains no content at all. The recipient sees no error signal, because every field has been filled. They see only an empty cell where data should have been — or nothing at all, because the system recorded "no anomalies."
Sports journalism is producing a version of that error every day.
A transfer report that is "complete but empty" has a structure that is easy to recognise if you pause for a few seconds. It has a club name. It has a player name. It has a fee. It has a vague timeline such as "in the coming days." It ends with a sentence beginning "the two parties are understood to be in talks."
Read it again and every field is filled. But the most basic question — who saw what, where, when — has no answer. Form is replacing verified content, and readers are being trained to accept it.
What makes this more dangerous than it appears is that it does not produce a neutral result. It produces the impression of a conclusion. Readers do not walk away thinking "I do not know yet." They walk away thinking "this deal looks close," and that impression is repeated, forwarded and cited until it becomes part of the collective memory of that window.
I saw this on a small scale in 2026. The rumour I chose not to publish lived on in people's mouths for two more weeks after the play-off, even after the facts were clear. Watching my club touch the edge of relegation in 2026, I understood that the truth does not need embellishment — but it does need to be repeated more often than a rumour.

In 2026 the problem is no longer a single rumour. It is a mechanism. The mechanism runs on a simple loop: one account posts structured information with no traceable origin; a small outlet cites it without checking; a larger outlet cites the small outlet as a secondary source; and finally an account with a large following cites the larger outlet with the phrase "according to multiple sources." After three steps, information with no origin has acquired three sources.
This is the point I want to press, because it runs against most readers' instincts. The fact that an item is reported in many places does not make it more credible. In most cases it only proves the item travels well.
When I worked in Madrid in the late seventies, I learned a principle from editors older than me: before writing, identify the first origin of the information. Not the source you read. The source the others read. If you cannot trace it back to a starting point, you do not have information. You have a copy.
That principle was right in 2026 and it is right in 2026, with one difference: tracing back to the origin is far harder now, because each time information is copied it is rewritten slightly — a few words changed, a detail added, a condition removed. After five steps, the original and the circulating version share only the player's name.
There is a very simple test I still use and still recommend. When you read a transfer report, ask yourself: if every proper noun and every figure were removed, would anything remain that counts as information? If what remains is only lines such as "the two parties are in talks," "the player has not closed the door," "the club is considering its options," then the report contains no information. It contains a template.
That is why I never write transfer news from a single source, even when the source is someone I have trusted for years.
Colleagues often ask me why I am slow. I answer with a number: over roughly the past fifteen years I have passed on at least two hundred transfer stories for which I had enough preliminary material to write. Of those, I estimate about half were false. The other half were true, but had I written them at that moment I would have written them wrong — writing them earlier than the truth, with details that later turned out completely different.
The cost of missing a true story is lower than the cost of publishing a false one. That is not a moral position. It is an empirical conclusion drawn from watching how the market reacts to errors over decades.
The news can wait, but the truth must never be delayed.
During a transfer window people reach for quantitative indicators as a way out of ambiguity. I understand the wish, but I have to say plainly that most of the metrics cited most often in modern football are the most misleading ones.
Possession is the clearest example. A team holds sixty per cent of the ball, but much of that time is spent on sideways passes inside its own half, changing nothing about the opponent's positioning and adding nothing to the probability of scoring. Reading the post-match sheet, that team looks in control. Sitting in the stand, you see the opposite.
The transfer market has metrics of the same kind. Views, shares, citations — all measure spread, not accuracy. A false report shared two hundred thousand times does not become true on the two hundred thousandth share. It becomes a widely circulated false report.
I am often described as a data sceptic. That is not accurate. I am sceptical of data without a definition. A metric has value only when you know how it was measured, by whom, over how long, and what question it is being used to answer.
People call me an opponent of data; in truth I only trust what I see on the pitch — and I read the stat sheet to check whether my eyes missed something.
Another example sits in refereeing technology, and it is closer to the transfer-market debate than people assume.
VAR arrived with a promise: to reduce controversy by supplying clear video evidence. After years of operation, controversy has not decreased. It has moved. Previously people argued about the referee's decision on the pitch. Now they argue about the camera angle, about which frame is chosen as the reference point, about whether contact crosses the threshold for intervention, and about where the offside line is drawn.
Controversy did not disappear. It moved from the grass into a room full of screens, and from the question "was the referee right" to a harder question — the question of law. VAR does not make the truth clearer; it makes the boundary of the truth clearer — and most of the argument sits exactly on that boundary.
Verification in transfer journalism runs on the same logic. When information is verified by citing its own original source, no error is removed. The error is relocated one level higher, where it is harder to trace. An item that has passed through three layers of citation looks more credible than a single-source item, even though both stand on exactly one leg.
This also means that the demand readers routinely make — "show the source" — is not enough. Sources must be tiered. A club confirmation, a registration list, a financial report: these are sources that can be contradicted. An untiered "according to a source" cannot be contradicted, and what cannot be contradicted cannot be trusted either.
Behind every number is a person; I do not write until I have heard their story — and in a transfer window that person is usually the one being sold, not the one doing the selling.
Here I want to put forward a counter-argument, because I believe it is the biggest blind spot among transfer-window readers today.
The common reading treats silence as a positive sign. A club produces no news for weeks, and people conclude the dressing room is stable, the plan is on track, there is nothing to fix. And when a club appears constantly in the press, people conclude it is active and ambitious.
Both conclusions are wrong in the same way.
Silence in a transfer window is usually the sign of a stuck process, not a settled one. It may be a contract extension still unresolved, a wage structure not yet worked out, a decision deferred because nobody wants to own it. It may also be a club waiting on something it does not control — another negotiation, a match result, a clause about to expire.
Noise is not a reliable indicator in the other direction either. Appearing frequently in the press is a cheap activity. A club can create the impression of acting decisively without completing a single deal, simply by letting a few information streams out at the right moments.
At this age I have realised that most of what I learned about the transfer market is really what I learned about people. When someone wants me to know something, I always ask why they want me to know it right now. It is a simple question, but it has filtered out more errors for me than any tool.
And there is a second, deeper blind spot. Readers tend to believe that a report with structure is a report with content. A report with a club name, a player name, a fee, a position and a timeline looks like a verified report, because its form matches that of a verified report. But structure is only a frame. A frame of the right dimensions does not guarantee that anyone is living inside it.
Those two blind spots combine into what I consider the most consequential outcome of any transfer window: the absence of information is misread as the presence of a conclusion. No news does not mean nothing is happening. No bad news does not mean everything is fine. And a report complete in form does not mean a report complete in content.
The mistake does not sit with the writer. It sits with the filter — or rather, with the fact that the filter was never installed.
So what will I be watching for the rest of this window?
I will watch the registration list before I watch any single line of reporting. That document is verifiable, and it usually says more than any interview.
I will watch the wage line in the most recent financial report, because it shows whether a club genuinely has room to add a player, regardless of how many names it is rumoured to be pursuing.
And I will watch expiry dates — contract expiry, release-clause expiry, registration-deadline expiry. Dates are the one category of information an agent cannot reshape to their own advantage.
A screen cannot replace the pitch; forty years holding a pen, I have kept that principle. But I will add something I have not said in previous pieces: in a transfer window, the most dangerous thing is not a lie. A lie can be contradicted. The most dangerous thing is an empty result presented in the shape of a complete one — because it offers nothing to contradict, and therefore no way to repair.
When I closed that drawer at twenty to three that morning, I did not know whether the message was true or false. Three weeks later, I still did not know. Perhaps I never will, and that is the normal condition of anyone who writes. What I can do is make sure that if I ever write about it, every sentence in my piece can be contradicted — and still stand afterwards.
