A Document With Nothing In It
On my desk in Valencia there is a twenty-page stack. Nine analytical sections, six data tables, four risk scenarios, a risk matrix and a glossary of technical terms. In every cell, the same line is printed in even type: not enough information to assess. No team name. No player name. No dates. No source. I read it through once, made more coffee, then read it a second time. And I concluded that this is the most honest document I have held in more than forty years of working in this trade.
Anyone who has stood behind the fence at the Paterna training ground on a February afternoon knows the feeling that comes with those empty cells. You have taken the forty-minute bus ride. You are standing at exactly the distance I still call one and a half metres: close enough to hear studs grinding through wet grass, far enough that nobody has to perform for you. That day the reserves played the under-19s, nobody announced the score, three senior players only jogged laps. You have two options: invent a story about inside sources, or close the notebook and write one short line. The trade taught me that the second option is far harder.
Seen from 1.5 metres, everything can be confirmed or denied. You see which player walks out of the medical room with an ice pack. You see who stays out an extra twenty minutes hitting free kicks while his teammates have already boarded the bus. You see a twenty-year-old boy bending down to wipe his boots clean before stepping into the tunnel — a small detail I wrote years ago, and it travelled faster than any transfer story I have ever filed. What you cannot verify from that distance are the empty cells in a document. And those empty cells are exactly the ones most likely to get filled.
The Certainty Factory
Modern football does not lack data. It has so much data that every training session is photographed, every match carries hundreds of metrics, every player has a digital profile. Data vendors sell to clubs and sell to newsrooms. Clubs publish training footage as a way of controlling the story. Agents ring reporters. Aggregator sites translate and republish. Within twenty minutes, a throwaway sentence in a corridor can appear in twelve languages using the same confident verb.
That rhythm leaves no room for pauses. I write one heartbeat slower than the game so I do not miss the moment studs touch grass — but in a newsroom that runs by the minute, writing slowly is a decision with a price. It means accepting that you will be beaten. It means watching a colleague publish fifteen minutes ahead of you, exactly the fifteen minutes you spent making a phone call to verify something. For years I have asked myself why this profession produces so many certain statements when the hit rate of most transfer claims is barely better than a coin toss.
Handling the Null
In any serious information system there is a rule I learned early and still use today: when there is no data, the cell stays empty, with a note that the basis is insufficient. People call it null handling. The principle is simple: gaps are allowed to exist, but guesses are not allowed to wear the costume of conclusions. A thirty-page analysis that says nothing but not enough information sounds useless. But it is clean. It does not plant in a reader's head an assumption that will later be cited as a fact.
I have seen the cost of filling a gap. One summer, a newspaper reported that a young Valencia midfielder had agreed personal terms with a foreign club. It was written as a statement, with no specific source and no date. Three weeks later, the player signed an extension with Valencia. Nobody published a correction, because corrections do not generate traffic. But from then on, every time that player's name appeared, people remembered that he had once nearly left. An assumption raised in three seconds outlived a contract that actually existed.
Four Tiers of Source
I still sort sources into four tiers. Tier one is an official announcement from a club or league, dated and documented. Tier two is a direct quote from a player or coach, recorded or witnessed in person. Tier three is an agent, and that tier is only worth trusting when their interest in the information going public is clear. Tier four is second-hand aggregation. Most of the transfer stories that go viral sit in tiers three and four, yet they are written in the language of tier one.
The line between tiers is a matter of survival. An agent called me during the 2026 World Cup in Qatar to say that a player I had followed since his days practising free kicks wanted a loan move abroad and nobody knew yet. I sat on it for three days. In those three days I interviewed twelve Valencia supporters in Doha, recording every sentence, every expression, every beer pushed aside when they heard the news. When I published, the most-read part was the part about how the people in the stands felt. The player's family called to thank me.
Twelve Empty Cells and One Real Match
Back to the empty cells. When an analysis has no sources, the right thing is to stop and demand the raw data. But there is a more dangerous kind of empty cell, the kind filled with metrics that look beautiful. Expected goals, passes allowed per defensive action, possession share, distance covered — all useful, on one condition: a large enough sample, plus tactical context attached.
A single match with high expected goals and no goals tells you almost nothing. Ten such matches start to speak. Thirty speak loudly. Yet in daily coverage, people still use one match to conclude something about a season, and one season to conclude something about a player. I have sat in press rooms many times while a coach was challenged over his team's poor finishing. He answered: we are creating chances, the goals will come. Three weeks later the goals came. Nobody went back and asked the old question again.
The same problem runs through transfer valuation models. Those models are excellent at measuring the potential of a nineteen-year-old: minutes played, touches in the box, the growth curve of his metrics season by season. They are poor at measuring what does not appear on a chart — who speaks in the dressing room after three straight defeats, who pulls the young players off their phones before lunch, who the assistant coach trusts to stand at the front of the wall. A thirty-one-year-old with per-match numbers identical to a nineteen-year-old will be called finished by the model. The dressing room calls him the anchor.
I am not dismissing data. I live on data. But data only answers the question someone already knows how to ask. We measure distance covered and call it intensity. We measure pressing actions and call it commitment. The endurance of a player carrying a minor injury through one hundred and eighty minutes in a week is not measured, so we file it in the appendix.
The Night in Moscow
On a June night in 2026 in Moscow, I sat in a bar with about fifty Spain supporters. The match against Iran had ended with a single goal, and on the pitch there was nothing to discuss. Off the pitch there was: the coach had been replaced two days before the opening match, an assistant was pushed into the hot seat, and the whole dressing room entered the tournament without a functioning captain's armband. The people in the bar split into two camps and described each other in words I would rather not record. I do not take sides, I just write down how the beer falls and how a generation swears. My piece was titled about the sadness of having no captain's armband.
The outside view of that night would certainly have been tactical: how the team controlled possession, where the space between the lines was, why a deep-defending opponent was so hard to break down. All of that was true. But it missed what you feel at one and a half metres: a group playing on professional instinct, not inside any system installed in two days. The blind spot of the outside view is that it always looks for a shape, when what was missing was a voice.

Day Forty-Seven
In 2026, Mestalla closed, and I lost my main sources: the dressing room, the corridor, the car park. I set up a private Telegram group. Three hundred members, mostly hardcore supporters, many of them cursing the club in sentences I would not dare translate. Every evening I turned on the camera and read their messages aloud, including the ones saying I had defended this club for too long. On day forty-seven, I received a gift with no wrapping paper: a video shot in the rain. A member called José had filmed a young Korean player training alone on a pitch behind his house, in the rain, at eleven at night.
I do not need the dressing room to open, as long as one fan opens up. That video started a series I still regard as the most important work of my last twenty years. But it taught me the opposite lesson too: once your sources become a community, the community has to become the filter. Everything entering the group passed through a single question — has a second person seen this. Four confirmations and I write. Nobody at all, and the cell stays empty.
The Blind Spot of the Spreadsheet
The reward system of this trade does not reward caution. A headline with might gets fewer readers than a headline with will. A story carrying a not yet verified line is treated as weak. So when you open any channel on a Tuesday morning you find a world written in ten-out-of-ten certainty, where every negotiation is at an advanced stage, every injury is minor, every coach is about to be sacked. This is the product of an incentive structure, and information quality is only a secondary variable.
Ironically, supporters demand certainty least of all. They demand respect. Among the three hundred people in that Telegram group, nobody needed me to say the club would stay up. They needed me to say what I had seen, where, and when, and that I knew nothing about the rest. When I wrote exactly that, they stayed. When I tried to look as if I had everything under control, they left — and they left precisely when I needed them most.
Signals to Track
For the rest of this season I have set myself three signals to track, and I invite readers to track them with me. First, a story is only trustworthy when it carries a date and a source tier: who said it, to whom, and when. Second, watch whether the language of the piece matches the tier of the source. A flat assertion built on an unnamed agent is a red flag, no matter how plausible the content sounds.
Third, and this is the signal I like most: compare behaviour with the claim. If a club says it is building around its academy, look at the actual minutes played by under-22 players over the last ten rounds. If a coach says he believes in possession, look at the number of long passes under pressure. Behaviour is always a tier-one source before any press release goes out. That is why I still stand at the training ground on afternoons when there is nothing to write.

The twenty-page document with the empty cells is still on my desk. I have not reprinted it, but I am keeping it. It reminds me that in an industry that manufactures certainty at industrial speed, admitting you do not know yet may be the most radical professional act available. There are evenings when I choose to stay at the ground instead of going home, and I get a story nobody has told in return. There are other evenings when I go home with a blank notebook, and I think that is a story too — if the reader is patient enough to believe that silence is not the same as giving up.
And you, reader opening the feed at six in the morning: do you want me to tell you what I know, or do you want me to tell you what you want to believe?
