Pressing at the Vélodrome: Marseille, De Zerbi and the Trap the Data Cannot See

At the Vélodrome there is a moment I have witnessed often enough to stop being startled by it, yet never often enough to stop wondering. Four Marseille players leave their positions at once and hurl themselves at a defender who has just received the ball. The whole stand holds its breath. Then either the ball is stolen amid a roar, or it slips through the gap between two white shirts, and behind them lies a vast emptiness waiting only for one pass.

People call it pressing. I call it a gamble dressed in the robes of science.

Since Roberto De Zerbi arrived in Marseille in the summer of 2026, that gamble has become a kind of religion. The Italian coach made no secret of his intent: to turn Marseille into a team willing to play, willing to take risks, willing to push its back line up to the halfway line and leave behind a stretch of land any striker would covet. That is the declaration of a man who believes football is won in the opponent's half, not in your own. And the supporters, after years of living with a lingering disappointment, fell in love with the idea instantly.

To understand why this story matters, it must be placed in the wider context of Ligue 1. For more than a decade the French league has lived inside a paradox: it produces the best players in the world and then sells them before they can win anything at home. Ligue 1 is a school, not an empire. Every summer, the youngest, fastest and boldest talents head off to England, to Spain, to Italy. The clubs that stay behind survive by inventing ideas rather than buying stars.

The transfer market is a match without a referee, where every number is a free kick. And in a league like this, pressing becomes the cheapest commodity and the most expensive one at the same time. Cheap, because it demands no money, only organisation. Expensive, because it demands absolute precision; a single man off the beat and the whole system collapses. When De Zerbi arrived, he brought a near-religious faith in the control of space. But what interests me is not that faith. What interests me is how people measure it.

For years, analysts have used a metric called PPDA — the number of passes the opponent completes before each defensive action by your team. The lower the PPDA, the more aggressively a team presses. It is an elegant number, charming, easy to quote in commentary. And that is exactly why it has become dangerous.

Data does not score goals, but it knows where the ball is going. PPDA tells you how many times a team charges forward, but it stays silent on the more important question: how many of those charges were the right decision, and how many were simply panic neatly organised?

I spent an entire season rewatching Marseille's footage. Not to count how often they won the ball, but to count how often they were nearly cut open. And I found something the statistics pages never tell: most of Marseille's successful presses began not when they charged, but a few seconds earlier, when the opposing defender was forced to turn his back on his own goal.

Pressing is not the act of winning the ball. Pressing is the art of planting fear in the opponent's mind before he even receives it. Numbers cannot capture fear. But fear is what decides matches.

Here I must be honest with myself. Years ago, as a young editor in Marseille, I wrote a three-thousand-word piece about Zambo Anguissa, then wearing the shirt of the city's club. I logged 127 ball recoveries in the opponent's third and called pressing a rhythmic net. The piece was widely shared, more than anything I wrote for the newsroom that year. But looking back now, I see I was right for the wrong reason.

I thought I was praising a player. In truth I was praising a moment when the opponent lost his composure. Anguissa did not win that ball because he ran faster. He won it because the man opposite had seen the colour of his shirt before the pass was made, and his foot had been trembling since then. That is what the elegant metric never tells you.

Watching De Zerbi build Marseille, I realised he understands this too, perhaps differently. He does not teach his players to run more. He teaches them to stand in the right place so the opponent has nowhere left to pass. A team is not just eleven men; it is a system of equations that knows how to run. And in that equation, the most important unknown is not in the feet of Marseille's players but in the heads of their opponents.

In modern football there is a concept coaches call the pressing trap. It is not charging at the ball. It is leaving the opponent a single option, and that option leads straight into a trap already laid. A good attacking player always has at least two passes in mind. The good presser erases one of them before the opponent notices. By then the defender's decision is no longer a decision; it is only the reflex of a man forced into a corner.

The goalkeeper, in such a system, is no longer a gatekeeper. He is the first player of the pressing structure. When the opponent's keeper has the ball, an entire Marseille forward line moves as one, not to win the ball but to redraw the map of available passes. They do not run at the ball. They run at the gaps the ball might travel into. And in those seconds, the match is no longer a race; it is a geometry problem solved in silence.

But every pressing system pays a price. That price is measured in calories, in age, in the days of rest between matches. A high-pressing team does not only attack the opponent; it attacks its own physical lifespan. In the Premier League, where clubs have budgets many times those of Ligue 1, pressing is built on a foundation of fitness managed as carefully as a financial asset. Specialists are hired, every gram of muscle measured, every rest minute calculated. In Ligue 1, the same system is run on thinner resources, and that thinness shows most clearly in April, when the legs grow heavy and every charge becomes a pilgrimage.

There is one match I will never forget. It was a cold November evening, and the visitors came to the Vélodrome with the faces of men who already knew their fate. From the fifth minute, their back line passed the ball sideways more than necessary, as if time-wasting while the score was still level. That was the first sign of collapse. Not a conceded goal, but a posture. They no longer believed they could play. And Marseille, like a beast scenting blood, charged.

The goal came in the 34th minute, and notably it began from a goal kick by the opposing keeper. The record will say: a goal from an individual error. I wrote in my notebook: a goal incubated twenty-nine minutes earlier by a system that knows how to plant fear. Football, at its deepest level, is not a sport of goals. It is a sport of decisions made in less time than a single breath.

But this is where I must turn in another direction, because the story of Marseille under De Zerbi is not a purely beautiful one. It has a reverse side, and that reverse side is precisely what I want to address. Look at the matches Marseille lost. In most of them, De Zerbi's team still pressed. Their PPDA was still low, still beautiful, still praiseworthy on the analysis boards. But the results were not. And here is the crux: when a system fails, people usually blame the execution. The players did not run enough, they lacked focus. That is the easiest explanation and the most dishonest one.

The truth is that a pressing system never fails for lack of effort. It fails because the opponent finds a way to turn that effort into a losing investment. Every time Marseille charges and fails to win the ball, it loses not just a chance. It loses energy, loses position, and more importantly loses the illusion of control. And the illusion of control is what a coach needs to sleep at night.

I spoke with a young Ligue 2 coach a few years ago. He told me that after reading an article of mine about Mbappé, he used it as teaching material. It struck me: if an article can teach a coach something, it can also teach him something wrong. Mbappé's speed is not for running; it is for cutting a blade across time. But if you teach your players that football is a race of blades, you will produce a generation of fast players who do not know where they are running. The same goes for pressing. If you teach a player that charging forward is always good, you are teaching him to kill himself in an organised way.

This is the counter-intuitive view I want to place on the table: in modern football, pressing is no longer a weapon. It has become a ticket to being considered modern. Every club wanting to prove its progress must press. And because everyone presses, what was once an advantage has become a minimum standard. When everyone carries the same weapon, the weapon no longer kills anyone; it only distinguishes those who know how to use it from those who use it under social pressure.

And here De Zerbi emerges as a more complex figure than people assume. He does not press because it is fashionable. He presses because he believes in something else: that football is a game of space, and space can only be conquered by forcing the opponent to abandon it. What is worth noting is that this belief is correct. But the correctness of a belief does not guarantee the correctness of a result. Football is where correct beliefs often lose to timely decisions.

Let us talk about time, because every pressing system is a system of time management. A successful press compresses the match: it turns a ninety-minute game into a string of three-second moments where everything is decided. A failed press stretches the match out, and stretching is the enemy of every structure. The longer a team becomes, the greater the distance between its lines, and distance is the space where fear breeds. In other words, pressing is not an attacking tactic. It is a tactic for controlling collective psychology. And like every psychological tool, it can turn and bite its owner.

I have a habit when watching football: I do not look at the player with the ball. I look at the players without it. In a press, the most interesting figure is not the player charging but the opposing defender standing ten metres from the ball, eyes flicking between two options, his foot slowing. That moment, the moment the foot slows before the decision, is where the match is truly decided. Numbers do not see that moment. Numbers only see its result.

This is why I say PPDA has been misused. It is not wrong; it is simply not enough. It is like judging a piece of music by counting its notes. You can know how many notes a symphony has, but you will never know whether it is sad or joyful. And football, at its deepest level, is always a question of emotion before it is a question of statistics.

In Marseille I have seen this again and again. Those evenings when the Vélodrome roars, not because the home side scored, but because the home side just forced a turnover in midfield. That roar is not for a goal. It is for a moment of power: the moment one collective forces another to submit to its will. And then, somewhere amid those roars, I ask myself: are we praising something good, or merely an imposition organised beautifully?

There is an aspect rarely mentioned in analyses of pressing, and I believe it is the most important one: its ethics. When a team presses, it does not only attack the ball. It attacks the opponent's space. And in football, space is the only asset a weaker team owns. A small club may have no money, no stars, but it has space, and space is what it can protect. Pressing against them is an assault on the only thing they have. That is why I always feel ambivalent praising a beautiful pressing system. I am praising something beautiful, but I am also praising something powerful. And in football, power is never neutral.

Perhaps you will ask: so what should De Zerbi do? If pressing is not the answer, and deep defending is not either, then where is the path? My answer is: there is no path. There is only the right way of reading a match. Football is not a problem with a fixed solution. It is a dialogue, and each opponent is a different language. De Zerbi reads one kind of opponent well and another kind less well. That is not a flaw. It is the human condition. Even the greatest coaches in history were only good against a certain set of opponents, and often failed against teams that knew how to break their language.

What I want to say is this: we have spent too long searching for the perfect system, when what we truly need is flexibility. And flexibility cannot be measured by PPDA. It can only be seen in the moments when a team changes how it plays mid-match, not because the opponent forced it, but because it realised it needed to change. That is what I call tactical wisdom. And it is not contained in any number.

Looking back at Marseille's journey under De Zerbi, I see a team learning to grow up, but growing up painfully. There are evenings when the Vélodrome blazes, and evenings when it is silent as a church after mass. In those silent evenings, I hear what data cannot convey: the loneliness of a system when it no longer believes in itself.

An empty stadium is a mirror: it does not reflect the crowd, it reflects the loneliness of the game. The pandemic of 2026 taught me that, and I realised this loneliness does not only come when the stands are empty. It also comes when a team has eleven men on the pitch yet plays as if alone. And in moments like that, every number becomes meaningless.

When I look at Marseille's signings in recent years, from the youngest names to experienced players like Mason Greenwood or Adrien Rabiot, I see something familiar: a club trying to buy back time by buying back youth. But time is not something that can be bought. It can only be used. And every club has only a finite number of moments to use it well.

I remember a young colleague at the newsroom who once told me, half-joking, that I was the last man writing about football as if it were a myth. I accepted being called outdated. But I think he was wrong on one point: I do not write about football as a myth. I write about football as a text that must be read slowly. And every text, to be understood, needs a patient reader. The sad thing is that the speed of the modern world does not nurture patience. It nurtures headlines. And headlines never read a match.

There is one thing I am sure of after thirty years in this trade: football has not changed as much as people think. What changes is how we tell it. In the 1980s, people praised the individual. In the 2000s, they praised the system. Now they praise the data. But the match is still the match: twenty-two men, one ball, and a finite stretch of time to make decisions that cannot be taken back. And within that finite time, the only thing that never changes is the tension between what we want to do and what we can do. That is the human tension. That is the tension of a defender standing before a ball and a man charging at him.

Perhaps that is why I still sit here, in Marseille, writing about football in a language no one asked me to write in. I do it not because I believe I am right. I do it because I believe there are things about a match that can only be seen if we pause long enough to look. When I look at Marseille's numbers, I do not see a perfect system or a failed one. I see a group of people trying to believe in something, in a sport where belief is always tested by unpredictable moments. And that, to me, is already a good enough story to tell.

What I want to leave behind, instead of a conclusion, is a question I carry every time I sit before the screen: if we stopped counting and started looking, would we see what the numbers are trying to hide? Because the dream of football never lies in the result, but in the moment the ball has not yet touched the ground. And in that moment, no metric can tell us what will happen next. Only people, and fear, and courage.
