Dingert Appointed VAR for Türkiye–France: How a Refereeing Controversy Migrates Across Competitions

When UEFA published the officiating team for the Türkiye–France match, I read the list out of old habit: main referee first, then the two assistant referees, then VAR. The name that stopped me was on the last line. Christian Dingert.

Three weeks earlier, in Lisbon, Okan Buruk said at his post-match press conference after Galatasaray's 3-1 defeat to Sporting that if it were up to him, he would end the refereeing career of the German official. He added that this referee should not be given another Champions League match.

Now Dingert has been given a match. Not a Champions League match. An international fixture. His role is VAR — the man behind the screen, the one with the power to overturn a decision already made on the pitch.

That coincidence has a strange pull. To a sports editor, it is a news item. To a data analyst, it is a different question entirely: why does this news item exist, and how many real facts does it rest on?

I opened the spreadsheet for Sporting–Galatasaray. It was empty. No publicly published xG. No PPDA figure. No positional heat map. We have exactly three data points: a 3-1 scoreline, a complaint, and an appointment.

Every model is wrong, but a few are wrong in a useful way. Here, the model is not a probability algorithm. The model is the way a football nation builds trust in referees — and the way that trust erodes, match by match.

What I want to do in this piece is not to judge Buruk, nor to defend Dingert. I want to dig down into the sediment where a media story was constructed, to see how many bricks of data it stands on — and which brick was crooked from the start.

Lisbon, the press conference, and a hypothetical scoreline

Galatasaray entered the Champions League as Turkish champions. Their opening fixture took them to José Alvalade, where Sporting have beaten more than a few European sides over the past two seasons. The final score: 3-1 to the hosts.

Buruk walked into the press room and did not talk about his defence. He talked about a red card. It was an indisputable red card, in his words. He added that had the referee shown it at the right moment, Galatasaray could have won 3-0 or 4-0 in Lisbon.

That hypothetical scoreline — 3-0 or 4-0 — is a coach's number, not an analyst's number. Across twenty-eight years of reading numbers like this, I have learned one thing: when a coach utters a hypothetical scoreline, he is not talking about football. He is talking about his own pain.

What stands out is that Buruk offered no data to back the claim. No xG. No shot count. No exact minute of the incident. Only an absolute assertion — indisputable — and a hypothetical consequence — 3-0 or 4-0.

In model logic, this is a basic error: assigning a certain outcome to an unverified variable. Had the red card been shown, the match would have followed an entirely different trajectory — and nobody, Buruk included, knows where that trajectory leads. Football does not operate by linear causation.

I have watched a great many matches in which a team played with a man advantage for the final thirty minutes and still failed to score again. I have also watched matches in which the numerically inferior side scored the decisive goal. Numerical superiority is a weighted variable, not a guarantee of outcome. When someone says a red card would have turned 1-3 into 3-0, he is describing a parallel universe, not the match that was played.

The appointment and optical facts

UEFA assigns referees through a technical process. Lists are built on internal rankings, competition experience, nationality, and personal schedule. A German official working as VAR for a Türkiye–France match violates no clause. Procedurally, the appointment is valid.

Procedural validity does not mean it creates no problem. In football, there is a category of fact I call the optical fact — true technically, wrong visually. Dingert is VAR for Türkiye, three weeks after a Turkish coach publicly said he would end the man's career. The fact is valid. It is also a media bomb.

For Turkish media, the story is told in a familiar template: European referees are biased against Turkish teams. The template is not new. It has existed for decades, across generations of referees and competitions. What is new is that it has now attached itself to a specific name, in a specific context, on a specific schedule.

And here is the point I think many miss: once a story attaches itself to a name, it begins to live a life of its own. It no longer depends on data. It depends on collective memory. And collective memory, in football, is a data type with very high latency and very large error bars.

The empty spreadsheet

Now we reach the hardest part of this piece, and the part I like best: talking about what we do not know.

We do not know the xG of Sporting–Galatasaray. We do not know how much possession the visitors had. We do not know the minute of the alleged red-card incident. We do not know which player was involved. We do not know the score at the time.

We know three things. First, the final score was 3-1. Second, Buruk believes a red card was missed. Third, Dingert has been appointed VAR for Türkiye–France.

Placed side by side, those three facts create a story. But that story is not an analytical conclusion. It is a narrative conclusion.

Data disappearing is not data loss — it is a type of data. The emptiness of the spreadsheet is informative here. It tells us that this controversy was never built on a foundation of measurement. It was built on feeling. And feeling, in football, is an extremely hard data type to verify.

In my profession there is a constant temptation: to fill gaps with inference. When there is no xG, people infer from the scoreline. When there is no shot count, people infer from impressions. When there is nothing at all, people infer from memory. I have made this mistake many times, and each time I remind myself: every spreadsheet is a meditation, except that when the meditation ends you have lost money.

The archaeology of a refereeing controversy

For years I have had an odd hobby: digging up refereeing controversies that have since gone quiet, to see what bricks they were built from. The result is usually the same. A refereeing controversy is rarely built from data. It is built from three ingredients: a moment of ambiguity, an aggrieved party, and a community searching for fairness.

The ambiguous moment in Lisbon, per Buruk, was a red card not shown. The very notion of an indisputable red card contains a paradox. If it were indisputable, why did it become the centre of a three-week dispute?

The aggrieved party is Galatasaray. They lost 3-1 and dropped points on the opening Champions League matchday. Under the new format — a single table, every point precious — such a defeat creates real pressure. That pressure needs a release valve, and the referee is the most convenient one.

The community searching for fairness is the Turkish fanbase. When these three ingredients blend, we get a complete story: a team robbed of its chance by a referee who failed to show a card.

When I read a story like this, I do not try to deny it. I try to find what it lacks. And what it lacks is usually a baseline dataset. How many times in Champions League history has a team been denied a similar penalty or red card and still won the match? How many times has the aggrieved side gone on to score more goals in the second half? Those numbers exist. They simply do not appear in the debate.

I once lived between two football cultures — Vietnam and China — and that taught me a lesson about how data migrates. A number born in one league, when it crosses a border into another, changes character. It loses context. It loses definition. It becomes a myth.

The migration of data

The Dingert story is a perfect example of what I call the migration of data — or, more precisely, the migration of a belief that has no data behind it.

It began at club level: a Champions League match between Sporting and Galatasaray. It moved to the individual level: a coach and a referee. It moved to the media level: a story about injustice. And finally, it moved to the international level: a VAR appointment for Türkiye–France.

At each migration it sheds a layer of original data and adds a layer of new emotion. By the time it reaches the international fixture, it has detached entirely from Sporting–Galatasaray. It is no longer about a red card in Lisbon. It is about a larger question: is European football treating Turkish football fairly?

That question is a good one, but it cannot be answered with three data points. And here I must confess something about myself: I prefer big questions to answers. It is my strength and my fatal flaw. People say I am good at predictions. Wrong. I am only good at saying the right thing at the right time.

In this case, what I can say at the right time is this: we are watching a migration of belief, not of data. And belief, once it has migrated, is very hard to bring home.

VAR and the paradox of transparency

There is an irony in Dingert being given the VAR role: VAR was created to increase transparency, but in this case it increases uncertainty.

VAR operates under a strict protocol. The VAR official can intervene in only four categories: goals, penalties, direct red cards, and mistaken identity. In every other situation, VAR has no right to speak. This means that even if Dingert wanted to intervene in a controversial moment during Türkiye–France, he could only do so if the incident fell into one of those four categories.

But the public does not read the VAR protocol. The public reads outcomes. And when outcomes disappoint, they reach for a name. Dingert becomes a symbol — not because he did anything wrong, but because he was placed in a position that invites suspicion.

This is a bias I call seat bias. Once a referee has been publicly criticised, every subsequent decision — right or wrong — is read through the lens of that earlier criticism. The effect is nothing new in psychology. It is only new in football, because football has never had enough data to measure it systematically.

Buruk's disciplinary risk

Setting aside the media dimension, this story has a legal dimension that I consider far more serious than it appears.

Buruk's statement — that if it were up to him he would end Dingert's refereeing career — falls into the category of remarks UEFA typically treats as an affront to the dignity of match officials. UEFA's disciplinary provisions protect referees from public criticism of a personally hostile nature. This is not the first time a coach has come under scrutiny for post-match remarks.

In this context there are three scenarios. Worst case: Buruk receives a touchline ban and a substantial fine. Central case: UEFA opens a case and issues a fine with a warning. Best case: no formal complaint is filed and the story stays within media bounds.

My emphasis: under the new Champions League format, a touchline ban can affect an important match far more than a fine. Money can be paid. A seat on the bench cannot be outsourced for cash.

And here is another blind spot: clubs have no real-time data to predict disciplinary risk. They react after a complaint is filed, not before. A simple model based on comment history and disciplinary precedent could provide early warning. Nobody builds it. Because building it produces no emotion.

Contrarian: correlation is not causation

Now I must address the hardest part — the part I know will annoy many people.

The Dingert story is built on a correlation: Buruk criticised a referee, and three weeks later that referee was assigned to a match involving Türkiye. The correlation exists. But is it causation?

My answer: almost certainly not.

UEFA assigns referees through a cyclical process. Dingert is an experienced FIFA official who has worked many international competitions. In a calendar as dense as the UEFA Nations League, top referees are rotated. Dingert appearing on the list is not an act of retaliation. It is the output of an administrative machine running on its own schedule.

But here is the point I want to stress: even if it is not causation, it can still become causation in another way. Not because UEFA wants it, but because the public will read it that way. And when the public reads an event as an act, the event begins to have real consequences.

This is what I have learned over years of working with data: sometimes what produces consequences is not the truth, but the belief about the truth. That belief generates its own consequences. A controversial VAR decision in Türkiye–France will be read through the lens of three weeks earlier. Even a correct decision will be doubted.

Football stopped rolling in 2026, but randomness has never taken a lunch break. In this case, the randomness is the appointment. But how people react to that randomness is entirely predictable.

Contrarian: the blind spot of 3-0, 4-0

I want to return to the number Buruk offered. Three-nil, four-nil. Had the red card been shown, Galatasaray would have won big.

There is a technical problem with this argument that few notice.

In football analysis we often posit a counterfactual world — a world in which a different event occurred. But the counterfactual world cannot be computed by intuition. It requires a model. And every model of the counterfactual world carries a very large error term.

Suppose the red card was shown in the twentieth minute. Galatasaray play with a man advantage for seventy minutes. In those seventy minutes, Sporting change their approach. They sit deeper. They defend in more layers. They accept ceding territory. Modern football contains a paradox: playing with a man advantage is not always easier. It creates a new kind of pressure — the pressure to score, to capitalise, to prove.

I have watched hundreds of matches in which a team played with an early man advantage and scored nothing more. I have also watched matches in which the numerically superior side conceded an equaliser. Nothing guarantees that a red card in Lisbon would have turned 1-3 into 3-0. That is a linear inference inside a non-linear system.

xG does not score goals, but it generates more argument than the actual ball. Here we do not even have xG to argue about. We have only a hypothetical scoreline uttered in the heat of the moment.

The paradox of the Türkiye–France match

Türkiye–France carries unusual symbolic weight. It is a meeting of two football cultures with a complicated shared history. For Türkiye, it is a chance to assert status. For France, it is a match they are expected to win.

In that context, a refereeing appointment becomes a variable. Not a technical variable, but a psychological one. If the match runs smoothly, the Dingert story fades. If there is a controversial VAR decision — right or wrong — the story erupts with far greater force.

This is an asymmetry I see in many refereeing controversies. Silence confirms nothing. Noise confirms everything. Once a referee is under suspicion, every correct decision of his is forgotten and only one wrong decision is remembered forever.

That raises a question about the system itself: how can a referee restore his reputation in the public eye? The current answer is: by never making a mistake in a big match. That is not a feasible standard. It is an unrealistic standard imposed on human beings.

Takeaway: signals for the next round

So what happens next, and what should we watch?

First signal: UEFA's disciplinary statement. If a formal announcement arrives before matchday, the story shifts from referee to coach. If there is no announcement, the story stays attached to the match.

Second signal: VAR decisions in Türkiye–France. One controversial intervention, right or wrong, will reactivate the entire story. A match with no interventions will let the story settle within weeks.

Third signal: Galatasaray's next Champions League result. Under the new league-phase format, every point matters. A positive result reduces pressure on Buruk. A negative result turns the refereeing controversy into part of a larger crisis narrative.

But if you ask me which signal matters most, I will say: watch how Turkish media describe Dingert's first decision in the match. Not whether the decision was right or wrong. Only how it is described.

Because here we are witnessing a phenomenon I believe sits at the centre of modern football: trust in referees is built on data but destroyed by narrative. A correct decision cannot rebuild that trust. A single wrong decision can destroy it in five seconds.

This is asymmetry. And asymmetry, in football as in markets, is where everything interesting happens.

I will follow Türkiye–France with an empty spreadsheet, as I always do. And I will add a note at the bottom: I will return to this subject once the match is over. Because this is the kind of story whose ending lies not in the match, but in what gets written about the match.

Data disappearing is not data loss — it is a type of data. And in this case, what has disappeared is the truth about the red card in Lisbon. It left the debate weeks ago. What remains is a name, and a belief that the name stands for something nobody has proven.

That is why I am writing these lines. Not to judge. But to record that, in football, a controversy can migrate far beyond its own origin.
