Introduction — 58th minute, a diving header
February 21, 2026, at the Metropolitano. The 58th minute of Atlético de Madrid's La Liga Matchday 25 match against Espanyol. A corner kick from the right. Matteo Ruggeri, stationed at the near post, redirected the ball's trajectory toward the far post with a header. Waiting there, Ademola Lookman hurled his whole body at it. The diving header crashed into the lower left corner. 3-1. It came just 19 days after his arrival at Atlético de Madrid.
A goal from a set piece. A flick at the near post, a finish at the far. It is a classic corner-kick pattern. To isolate this one play alone and use it to explain a relationship forged at Atalanta would probably be premature. But the fact that a player on his 19th day with the club attacked the far post without a hint of hesitation was, in itself, a small sign.
What this column follows, rather, is the quality of the combinations the two have shown in open play. Since the start of 2026, Ruggeri has recorded five assists in all competitions for Atlético, the most in the squad, while Lookman has made a high-level start with four goals and three assists in his first seven matches after joining. Why was the time they shared at Atalanta reactivated so quickly in Madrid? This column breaks down the blueprint from Bergamo and traces its reconnection in Madrid.
Chapter 1 — Gasperini's blueprint for the left side
It is impossible to discuss Atalanta's tactics without mentioning Gian Piero Gasperini. He managed the club for roughly nine years, from 2016 to 2025, and as a tactician he lifted Atalanta from mid-table status into a regular among Serie A's upper ranks and, beyond that, into a leading presence on the European stage.
Gasperini's base formation was a 3-4-1-2, sometimes a 3-4-2-1. The skeleton was simple. Three centre-backs marked their direct opponents man-to-man, and in the defensive phase both wing-backs dropped into the back line to form a back five. Once possession was won, the two central midfielders served as pivots to circulate the ball while the wing-backs surged forward, transforming the shape into an effective 3-2-5. It was these wing-backs who served as the system's arteries.
The role of the WB was a "third position," distinct from both a pure SB and a winger. Out of possession they were absorbed into the defensive line to form one part of a back five; in possession they held high positions close to the touchline to provide width. As Breaking The Lines has pointed out, in Gasperini's system, "the WB take high positions, effectively transforming the attack into a 3-2-5 and committing more numbers forward." For that transformation to work, WB needed unceasing up-and-down movement for 90 minutes and quick decision-making in attacking-defensive transitions.
Ruggeri looked like a player born for this position. He joined Atalanta's academy at age nine and absorbed Gasperini's tactical ideas almost at the DNA level. In November 2020, he made his first-team debut at 18 against Liverpool in the Champions League. After a loan spell at Salernitana, he established himself in the first team from the 2022-23 season onward.
José Rodríguez, a Serie A pundit for DAZN, described Ruggeri's traits this way: "He repeats high-intensity movement up and down the pitch and keeps participating in the press. He's made in Atalanta. It's not that one single ability stands out above the rest, but almost every element of his game is solid." Across 109 appearances for Atalanta, he posted two goals and 10 assists (Transfermarkt). On numbers alone, it looks modest. But the work of a WB resembles electrical wiring. You cannot see it, but if the wiring is not connected properly, no matter how advanced the lighting fixture is, it will not shine.
Chapter 2 — Lookman's transformation — from drifter to finisher
Ademola Lookman's career was never a straight line. He is from Wandsworth in south London. He joined Everton from Charlton Athletic but could not lock down a regular place, then went through spells with RB Leipzig, Fulham, and Leicester City before moving permanently to Atalanta in the summer of 2022. The Premier League, Bundesliga, Serie A, and now La Liga. It is a rare career path that has taken him through the top leagues of four different countries.
At Atalanta, Lookman changed. In 2022-23, he scored 13 Serie A goals and blossomed into a genuine scorer, earning the club's Player of the Year award. The following 2023-24 season, he produced 17 goals and 11 assists in all competitions (Atalanta official). He was the team's second-highest scorer and also second in assists.
Under Gasperini, the quality Lookman refined was positional multiplicity. According to Transfermarkt records, during his Atalanta years he was used in at least six positions: left wing, right wing, second striker, centre-forward, attacking midfielder, and left midfielder. That flexibility was precisely the trait Gasperini wanted.
In the context of this column, the most important point is the relationship between Lookman's stronger foot and his positioning. When Lookman, whose stronger foot is his right, is deployed on the left, he functions as an inverted winger. Receiving on the left and cutting inside naturally opens the shooting lane for his right foot. If the WB then makes an overlapping run on the outside, the opposing SB is forced to deal with two simultaneous threats: the cut inside and the overlap.
The scouting site YouAreMyArsenal describes one of Lookman's standout traits like this: "He uses both feet almost equally well for both shooting and dribbling." He can drive inside onto his right, or simply finish with his left. For defenders, it is hard to predict which foot he will attack with. That two-footedness widened the range of options in his combinations with the WB even further.
Every time Lookman narrowed inside, space opened up along the left touchline. Ruggeri was the one making the run into it.
Chapter 3 — The night in Dublin — the Europa League final as the point of arrival
May 22, 2024, Aviva Stadium in Dublin. The UEFA Europa League final: Atalanta against Bayer Leverkusen. Leverkusen arrived on that stage carrying a historic 51-match unbeaten run in official competition.
In Atalanta's starting eleven, Ruggeri was at left WB and Lookman was in the front line. The result was 3-0. A hat-trick from Lookman.
UEFA's official technical analysis described Atalanta's left-sided defending in that match in concrete terms: "Kolašinac and Ruggeri, against Leverkusen's Frimpong, were able to apply pressure while also keeping their body orientation toward the space behind. That allowed them both to discourage passes into Frimpong's feet and to hold a position from which they could break first if a ball was played in behind." It is a description that condenses the essence of Ruggeri as a WB.
Looking back at Lookman's hat-trick, a fascinating structure emerges. The first goal saw him ghost in from the blind side into the space De Ketelaere had created, finishing first time with his left foot. For the second, he shaped to attack down the left before cutting inside to strike with his right. The third came via a stepover off Scamacca's pass, finished with his left. As tactical analysis has noted, the right-footed cut-in of the second goal led Leverkusen's defence to over-commit to that threat in the third, and Lookman exploited the space left behind with his left foot.
None of the three goals went down as a direct assist from Ruggeri to Lookman. But as Breaking The Lines noted, "with WB Ruggeri and Zappacosta holding high positions and providing width and support," Leverkusen's defensive block was stretched toward the flanks, creating the central spaces where Lookman could receive. A structural contribution that does not appear in the stats. Ruggeri's selection in the competition's Team of the Season by the UEFA Technical Observer Panel can fairly be seen as recognition of exactly that kind of work.
On that night in Dublin, behind Lookman's three goals was the fact that Ruggeri remained the left side's ruler.
Chapter 4 — Separate paths, and then a reunion
In the summer of 2025, Ruggeri moved first.
Atlético, despite reported interest in veterans such as Robertson and Theo Hernández, signed the 23-year-old Ruggeri for a base fee of €17 million, rising to around €20 million with bonuses. Shirt number 3. At his unveiling, he said this: "The moment my agent told me Atlético were interested, I didn't hesitate. If I had needed to, I would have walked to the Metropolitano."
But life in Madrid did not go smoothly from the outset. He needed time to adapt to the La Liga environment, and in the early part of the season there were voices pointing to shortcomings in both attack and defence. Football Espana reported that "since arriving from Atalanta, he has endured an up-and-down season, and those inconsistent performances have at times led Simeone to use other players," while in December 2025 Yahoo Sports even mentioned the possibility of him being "demoted to a backup role." His average La Liga rating on FotMob was 6.97. As the numbers suggest, solid but unspectacular — that was Ruggeri's first half of the season.
The turning point came after the new year. As he accumulated matches, his understanding of Simeone's defensive principles deepened, and his performances began to stabilise. As Into the Calderon wrote, "Neither Ruggeri nor Cardoso was perfect. But both left traces on the match. At this stage of the season, that matters." Little by little, he built trust. Then in February, the arrival of his former partner would accelerate that upward curve.
Lookman, for his part, was enduring a difficult season. He had wanted a move to Inter in the summer of 2025, but the deal collapsed after Atalanta demanded a fee of €50 million — or €60 million, according to some reports. Distance grew between player and club. Under Ivan Jurić, who replaced Gasperini (appointed in June 2025 and dismissed that November), and then under Raffaele Palladino, his playing time dropped sharply, and he was limited to 797 minutes for Atalanta in the 2025-26 season. As ESPN's Graham Hunter pointed out, that total "would rank him 18th in minutes played if applied to Atlético's squad list."
On February 1, 2026, Atlético and Atalanta reached an agreement on a €35 million transfer. It was officially announced the next day. A four-and-a-half-year contract. Goalkeeper Juan Musso had already moved from Atalanta to Atlético as well, meaning that three men who had shared the Europa League final night were reunited in Madrid.
Chapter 5 — Restarting the left side
February 5, Copa del Rey quarter-final. Betis 0-5 Atlético. It was Lookman's debut.
One goal and one assist in 79 minutes. But more noteworthy than the numbers was the qualitative shift on the left flank. Into the Calderon wrote: "Ruggeri became more aggressive with his overlapping runs. The left side changed from 'functional but not dangerous' into 'a threat with intent.'" In the post-match thread on r/atletico, one user put it sharply: "Lookman was brilliant individually, but his chemistry with Ruggeri is incredible. He elevated Ruggeri's attacking game. And Lookman tracked back too."
When Lookman holds the width on the left, the opposing SB is forced to narrow inside to guard against the cut inside. In that moment, Ruggeri attacks the space created along the touchline without hesitation. It was the same movement they had repeated hundreds of times in Atalanta's 3-4-1-2, now naturally reproduced in a 4-4-2 in La Liga.
One week later, on February 12, came the first leg of the Copa del Rey semi-final. At the Metropolitano. The opponent was Barcelona. On Atlético's left side in the starting eleven stood Ruggeri and Lookman together.
The result was 4-0. Lookman finished with one goal and one assist. In his preview of the match, ESPN's Graham Hunter had predicted that "the left-sided duel of Lookman and Ruggeri against Yamal and Koundé would unfold over the two legs," and the game developed just that way. Lookman attacked from the left, Álvarez finished centrally. On the right, Giuliano Simeone and Llorente disrupted the defence through changing lanes. It was the clearest expression all season of an asymmetrical attacking design functioning as intended.
Then came the Espanyol match on February 21. The 58th-minute goal described at the beginning was born there. From a corner kick, Ruggeri flicked on and Lookman met it with a diving header. Then in the 72nd minute, Sørloth powered in a header from a Ruggeri cross from the left, giving Ruggeri two assists in the match. The formation may be different, but the principle is the same one Atalanta used, with the WB going outside and the forwards finishing inside: the wide player provides width and crosses, the central player applies the finish.
RotoWire reported that "Ruggeri, who recorded two assists over the weekend, added another assist in Tuesday's CL match (a 4-1 win over Brugge)." Ruggeri's five assists in all competitions since the start of 2026 are the highest total in Atlético's squad. In the first half of the season, he was described as "solid but unspectacular." Since the turn of the year, however, in addition to greater consistency, he has shown clear attacking growth following Lookman's arrival. The sample size is still small. But the trend is clear. Lookman's presence is sending current through Ruggeri's attacking circuit.
Conclusion — the completion of an asymmetrical shape, or perhaps the feeling of it
In this site's column "Right Side Anatomy", we analysed the shifting structure created on Atlético's right by Giuliano Simeone and Marcos Llorente. Out of possession, they drop into the defensive line; in transition, they accelerate vertically; in the attacking third, they break opponents down from the byline. It is a circuit that switches through multiple modes.
The design idea on the left is different. Ruggeri, as the SB, maintains width, while Lookman completes moves either by cutting inside or by finishing. There is no multi-stage transformation like on the right. But with Lookman's arrival, the left side — once "solid but functional" — has gained "intent and destructive power." The right deforms shape to break opponents down, the left finishes moves. Atlético's attack is finally beginning to take clear shape as an asymmetrical structure in which the two flanks carry different roles.
It is still too early to say definitively whether that asymmetry has reached its finished form. Lookman's Atlético career has only just begun, and Simeone himself has said, "We need to get to know each other little by little. The team has to get used to his attacking characteristics, and we have to work out what fits best."
But at the very least, one fact can already be confirmed. The circuit forged in Bergamo has also come alive in Madrid. Even if the formation has changed from 3-4-1-2 to 4-4-2, the principle of "the one who goes outside and the one who finishes inside" remains something the two share like a language.
From Bergamo to Madrid, the straight-line distance is about 1,400 kilometres. The time the two needed for the left-side circuit to come alive again was just 19 days.
