Two Back Threes in Dublin: Lookman, Gasperini and the Limits of Caution

On the night of May 22, 2026, at the Aviva Stadium in Dublin, both Atalanta and Bayer Leverkusen walked into the Europa League final with the same tactical foundation: a back three. Neither side chose a back four. There was no clash between two schools of thought. Twenty-two players, two nearly mirrored shapes, and a question I carried with me for months afterwards: when everyone chooses the same solution, is it still progress?

The result is already written into history: Atalanta won 3-0, and Ademola Lookman scored a hat-trick in the 12th, 26th and 75th minutes. It was one of the rarest hat-tricks a European cup final has ever witnessed, and it came from a player English football had once forgotten. But what I brought home from Dublin was not the scoreline. It was the feeling that I had just watched two teams choose the same road, then turn into two different directions.

I go to stadiums to listen, not only to watch. And that night, what I heard was the sound of a trend replicating itself.

The Context of a Cycle

The back three is not an invention of the 2020s. It has had cycles longer than the careers of most players active today. In the late 1980s and early 1990s, many European sides built a back three to cope with strike partnerships. By the mid-2000s, as football shifted to a lone striker and two inverted wingers, the back four became an almost absolute standard. Then, in 2026, an Italian coach named Antonio Conte rebuilt the back three at Juventus, and within half a decade, all of Europe relearned an old lesson.

Conte led Juventus to the 2026-12 Serie A title without losing a single match. He took that shape to the Italy national team at Euro 2026, then to Chelsea in 2026-17, winning the Premier League in his first season. From there, the back three spread everywhere: Tottenham, Inter, Atalanta, Sheffield United, and even small Championship clubs. By the 2026-24 season, it appeared at nearly half of the teams across Europe's top five leagues, at different points of the campaign.

But the striking thing is not the number. The striking thing is this: most teams that switched to a back three in the 2020s did not do it because they believed in it. They did it because they feared the alternative.

I have tracked this trend since 2026, when I was fresh in the job at The Tactical Room. My first live assignment was AFC Wimbledon against Accrington Stanley in League Two. I mispronounced defender Will Nightingale as "Will Night-in-gale" and repeated it three times in ten minutes. The match finished 2-2, but I cannot remember a single goal. For a month afterwards, I rewatched the footage and counted every touch, only to discover something nobody mentioned: there were seventeen passes strung together before the second equaliser. There were seventeen passes the whole world missed, and one writer counted them. From then on, I learned that numbers only matter when they tell a story the eye cannot see.

And the story of the back three in the 2020s is a story about fear.

Core: Same Structure, Different Spirit

Back to Dublin. Gian Piero Gasperini's Atalanta and Xabi Alonso's Leverkusen both built a back three, but they built it in two completely different ways.

Gasperini had been at Atalanta since 2026. He built a relentless man-marking system, where every Atalanta player knew exactly whom to follow and where to run when the ball was lost. His back three was not a shield to retreat behind. It was a launchpad to push forward. When Atalanta defended, their three centre-backs pushed up almost to the halfway line, marking tightly and turning the pitch into a cramped space with no room to turn. When Atalanta attacked, the wing-backs became forwards, the two central midfielders advanced as playmakers, and the shape looked like it had six attackers.

That is why Atalanta scored three. Not because they had more of the ball. The statistics show Leverkusen dominated possession for much of the game, completed more passes, and took more shots. But football does not award points for passes. It awards points for goals, and Atalanta turned every ball won into a chance.

For the first goal in the 12th minute, Lookman received on the left, took two tidy touches and finished across the goalkeeper. For the second in the 26th minute, he picked up the ball near the edge of the box after a teammate won a duel, turned and shot with his right foot. For the third in the 75th minute, he drove inside from the left, beat two players and scored with his right. Three goals, three different ways, the same man. People do not remember the match; they remember how a person rose.

Alonso's Leverkusen also built a back three, but with a different philosophy. Alonso constructed a possession-based system in which the three centre-backs were the starting point of every pass. They kept the ball, circulated it, and waited for opponents to lose patience. Across the 2026-24 season, that approach delivered something unprecedented: a Bundesliga title without a single defeat, and an unbeaten run stretched to 51 matches in all competitions before they met Atalanta.

But against a team that marks tightly, the system exposed its weakness. Leverkusen's three centre-backs were often forced to pass under pressure, and when they lost the ball, the space behind them was wide enough for a fast player like Lookman to exploit within seconds. That is the paradox of the back three: it creates safety, and it creates a new gap for opponents to target.

The Blind Spot of Beautiful Metrics

After the match, I read the numbers again. Leverkusen had a higher expected-goals figure than Atalanta in the first half. They dominated possession, passed more, and created more attacking situations. Looking only at those numbers, one might conclude Leverkusen deserved a better result. But the result was 3-0 to Atalanta, and no one can say the winners did not deserve it.

This is where I must say plainly what many in the profession avoid: expected goals has been overused. It is a useful tool for assessing chance quality, but it cannot explain a player's decision, cannot measure concentration, cannot account for a defender running seventeen metres to cover, and cannot see that a striker chose the right moment to accelerate. Those things lie beyond any model.

In seventeen years of watching football, I have learned that metrics tell us what happened on paper, while the match tells us what happened on grass. Sometimes the two stories align. Sometimes they diverge, and when they diverge, the writer must choose which to believe. I choose to believe the grass, but I never ignore the paper.

Core: Why the Back Three Returned

To understand why the back three returned so strongly in the 2020s, one must look at the pressure coaches face. Modern football has two parallel attacking trends: high pressing and attacking through the wide channels. To resist pressing, a team needs more passing options at the base. To resist wide attacks, a team needs cover across a broad area. The back three solves both problems at once.

Three centre-backs give a team three passing options at the base instead of two. When an opponent presses with two strikers, the three centre-backs create a numerical overload and open a free pass. When an opponent presses with three strikers, the wing-backs are often free higher up, offering a long escape route. It is simple mathematics, and coaches noticed.

At the same time, a back three allows the wing-backs to push higher without exposing the space behind. When the team attacks, the wing-backs become wide midfielders, and the three centre-backs hold the base. When the team loses the ball, the wing-backs drop into full-back positions, and the three centre-backs collapse into a back five. It is a flexible system, and over a long season, that flexibility has value.

But here is where I want to pause. That flexibility is not tactical progress in the most beautiful sense of the term. It is a way to minimise risk. When a coach builds a back three, he is saying he does not trust his back four to handle wide attacks. He is saying he would rather have an extra defender than an extra attacking midfielder. He is choosing safety over adventure.

And when every coach chooses safety, football becomes more alike. That is what I saw in Dublin: the two strongest teams in a continental competition built the same structure, and the match became a contest of who executed that structure better, rather than a contest between two different ideas.

Contrarian: This Trend Is Not Progress

There is a popular reading that the return of the back three proves football is evolving, that coaches are finding new solutions to new problems. I do not believe that reading.

Look at the history. Every time the back three returns, it returns for a specific reason, and that reason is usually fear. In 2026, Conte built a back three at Juventus after the team conceded too many from a back four. In 2026, he brought it to Chelsea after three straight defeats. In 2026, many Premier League teams switched to a back three after being dismantled by big clubs through wide attacks. In every case, the back three was an answer to a wound, not an aspiration.

That does not mean the back three is a bad shape. It means we are confusing reaction with progress. A coach who builds a back three to hide his weakness is doing the work of a risk manager, not a creator. And football, in the end, does not advance through risk managers. It advances through those willing to expose their weaknesses.

I wonder what would have happened if Alonso had built a back four in Dublin. Perhaps Leverkusen would still have lost. Perhaps they would still have been exploited by Lookman. But at least the match would have been a clash between two ideas, and viewers would have learned something new. Instead, we got a final in which the two teams were so alike that the structural difference is hard to recall.

There is one small detail I keep. In the second half, with Leverkusen trailing 2-0, Alonso sent on an extra striker. He did not change the defence. He only added a man up top, kept the back three, and tried to attack with numbers. It was a reasonable decision. But it also showed that even when he needed a goal, Alonso did not dare remove the back three. The structure had become a belief, not a choice.

Core: Lookman and the Story of a Forgotten Man

There is another aspect of the match I do not want to skip, because it concerns what I always try to do in this profession: put the person at the centre.

Ademola Lookman was born in Wandsworth, London, to a family of Nigerian heritage. He came through the Charlton Athletic academy, then joined Everton in 2026 for a fee of around 11 million pounds. He was regarded as one of the brightest young talents in English football at the time. But then he lost his way. Loan spells at RB Leipzig, Fulham and Leicester brought no stability. In 2026, he moved to Atalanta for a fee of around 15 million euros, and many in England saw it as the end of his top-level career.

At Atalanta, Gasperini gave him what English football had not: patience. He let him play on the left, allowed him to drift inside, and accepted his mistakes in the early months. By the 2026-24 season, Lookman had scored more than ten goals in Serie A and become one of Atalanta's most important attackers. Then, in Dublin, he scored three goals in a European final.

Mistakes are only commas, and the story continues on the next page. Lookman's career is proof of that. He did not rise through a resounding victory. He rose through quiet corrections, by accepting a stay in a place few Englishmen know, by trusting an Italian coach who trusted him.

When I watched Lookman celebrate his third goal, I did not think about the scoreline. I thought about the years on Leicester's bench, about being called a failure, about the time he nearly vanished from the football map. Cracks are not the end — they are where the light gets in. And Lookman's light got in on one night in Dublin.

Core: Atalanta and a Small City

There is one more thing about this match I want to write, because it concerns how I see football.

Atalanta are a club from Bergamo, a small city in northern Italy with a population of around 120,000. For most of their history, Atalanta were never a force. They were promoted and relegated, sold their best players to bigger clubs, and had no money to compete with Juventus, Inter or Milan. But since 2026, under Gasperini's hand, they have become one of the most exciting teams in Europe.

Gasperini arrived at Atalanta when the club sat mid-table in Serie A. He had no money to buy stars. He had to work with players other clubs overlooked, men like Lookman, like Marten de Roon, like Teun Koopmeiners. He built a system not on outstanding individuals but on a cohesive collective. And within eight years, he took Atalanta to three Coppa Italia finals, a Champions League semi-final, and finally the club's first Europa League title in its history.

It is a story about patience. In a football world where coaches are often sacked within months, Gasperini stayed at Atalanta for eight years. He was allowed to fail, to experiment, to build something slowly. And when the reward came, it came whole.

Every empty seat is an untold story. In Bergamo, there are thousands of empty seats whenever Atalanta play away. But the people watching their team on television at home, on the night in Dublin, had a story to tell their grandchildren.

Contrarian: What Atalanta's Win Does Not Prove

A popular interpretation after the final was that Atalanta's win proved Gasperini's back three was superior to Alonso's back three. I do not believe that interpretation.

If both teams built a back three, the difference was not in structure. It was in execution. Atalanta won because they marked better, ran more, and took their chances more efficiently. Leverkusen lost because they lost the ball in dangerous areas, and because they could not find a way past Atalanta's man-marking defence. None of that relates to whether a team plays three or four at the back.

This is a common mistake in tactical analysis: we attribute to structure what belongs to people. A shape is only a framework. It does not run, does not tackle, does not decide. Players do those things. And in a specific match, the difference between two teams usually lies in details no shape can explain.

In Dublin, that detail was Lookman. A player on a perfect night can beat any system. That is the most beautiful and least analysable thing about football. We can measure passes, pressing actions, shots. But we cannot measure the moment a player decides he will not lose.

And that is why I am always cautious about drawing tactical conclusions. After 2026, my voice became less certain. I learned that one match is not enough to prove a theory, and one player is not enough to define a system. Humility before the facts is not evasion. It is acknowledging that our data is always less than reality.

An Open Ending

The match is over, but the poem remains unfinished. Atalanta have won the Europa League, Lookman has scored a hat-trick, Leverkusen have lost their unbeaten run after 51 matches. Those facts will sit in the history books. But the question I brought home from Dublin still has no answer: is the back three still a tactical choice, or has it become a collective reflex?

I do not know the answer. But I do know that when everyone chooses the same solution, we should begin to doubt that solution. Football advances through those who dare to go against the crowd, dare to expose their weaknesses, dare to play a back four when the whole world plays a back three. Perhaps in a few years, some coach will do just that. And when he succeeds, all of Europe will copy him, and the cycle will begin again.

There is a sound to silence, and it rings louder than any hymn. In Dublin, after the final whistle, I heard the sound of a small city celebrating, and the sound of a trend asking itself whether it is still right.
