Inter arrived at San Siro with an unbeaten Serie A record. They left with their first league defeat of the season, three goals conceded and serious questions about their defensive organisation. AC Milan, meanwhile, delivered one of their most convincing derby performances in recent years, defeating their city rivals 3–1 in a result that was about much more than individual brilliance.
The Milan vs Inter showdown on 31 October 2026 was decided by a combination of intelligent tactical preparation, ruthless execution and outstanding individual performances. Ruben Amorim’s side scored through Christian Pulisic, Adrien Rabiot and Diego Moreira, while Alessandro Bastoni briefly gave Inter hope.
But the most revealing aspect of the Milan vs Inter encounter was the contrast between possession and effectiveness. Inter controlled more of the ball, attempted more shots and won more corners. Milan, however, understood where the decisive spaces were, attacked them with precision and defended their advantage with impressive discipline.
Diego Moreira was the headline performer, producing two assists and a stunning free-kick. Yet his performance was also a product of a wider tactical plan that allowed Milan’s attacking players to hurt Inter in specific areas.
Here are five tactical decisions that helped Milan win the derby.
1. Milan’s 4-4-1-1 formation disrupted Inter’s expected rhythm
One of Amorim’s most important decisions was his choice of formation.
Milan started with a 4-4-1-1 structure, placing Mike Maignan behind a defensive line featuring Mario Gila, Koni De Winter, Strahinja Pavlović and Sankhoun Diawara. Yunus Musah and Luka Modrić operated in midfield, while Moreira and Pulisic occupied the wide attacking positions.
Rabiot played behind Gonçalo Ramos, giving Milan a second attacking presence without sacrificing their midfield structure.
Inter responded with a 3-5-1-1 formation. Manuel Akanji, Alessandro Bastoni and Yann Bisseck formed the defensive three, while Nicolò Barella, Hakan Çalhanoğlu and Petar Sučić were among the midfield options. Andy Diouf operated behind the lone striker, Marcus Thuram.
The formations were designed to create different advantages.
Inter wanted to use their midfield numbers to control possession and progress through central areas. Milan, however, had a clear opportunity to attack the spaces around Inter’s wider defenders and wing-backs.
The important distinction was that Milan did not need to dominate possession to control the most dangerous moments.
Their structure gave them enough defensive protection while allowing the wide players to attack quickly when the opportunity appeared.
The opening ten minutes demonstrated how effective that approach could be. Milan scored twice before Inter had properly settled into the match.
The lesson from the Milan vs Inter tactical battle was clear: Amorim did not need to win every possession. He needed to make his team’s attacking moments more dangerous than Inter’s.
2. Diego Moreira’s positioning exposed Inter’s defensive weaknesses
If one player represented Milan’s tactical success, it was Diego Moreira.
The Belgian winger was involved in all three goals, providing assists for Pulisic and Rabiot before scoring a superb free-kick himself.
His first major contribution arrived after just four minutes.
Moreira attacked the right side, reached the byline and delivered a left-footed cross into the penalty area. Pulisic found space and headed the ball into the bottom-left corner.
The goal highlighted two important problems for Inter.
First, Moreira was able to advance into a dangerous crossing position. Second, Inter failed to protect the space in front of their goal effectively enough to prevent Pulisic from attacking the delivery.
The second goal, scored in the tenth minute, provided another example of Moreira’s influence.
His low corner found Rabiot, who produced a clever finish that clipped the far post before crossing the line.
Two goals in ten minutes had transformed the atmosphere of the derby.
Moreira’s influence was not simply about crossing ability. His positioning forced Inter’s defenders to make difficult decisions about whether to protect the central space, close down the winger or track the runners arriving into the box.
That uncertainty created opportunities for Milan.
For Inter, the problem was that their defensive structure was repeatedly being tested by different types of attacking movement. The first goal came from open play, while the second came from a corner.
Moreira’s contribution also demonstrated the value of having a wide player capable of creating chances without needing repeated touches in central areas.
In the Milan vs Inter derby, he was not merely an individual match-winner. He was the attacking reference point around which Milan’s most decisive moments were built.
3. Rabiot’s advanced role gave Milan another attacking weapon
Another important decision was Amorim’s use of Adrien Rabiot behind Gonçalo Ramos.
Rather than positioning Rabiot as a conventional central midfielder, Milan used him in a more advanced role, where he could connect midfield possession with the attacking line.
This created an interesting problem for Inter.
If one of their midfielders moved forward to close Rabiot, space could open behind that player. If Inter allowed him to receive the ball, he could turn, combine with the wide attackers or move into the penalty area.
His goal in the tenth minute illustrated the value of his positioning.
Rabiot attacked the delivery from Moreira’s corner and finished with precision. It was an important reminder that midfielders can be dangerous not only through long-range shooting or passing but also through intelligent movement into scoring positions.
Rabiot’s wider contribution deserves attention as well. Opta noted that he had scored or assisted in each of his previous five Serie A matches, recording four goals and two assists across that run.
That consistency gives Milan another source of attacking production beyond their recognised forwards.
In a derby, where defensive attention naturally focuses on players such as Pulisic and Ramos, the late arrival of a midfielder can become extremely difficult to track.
The Milan vs Inter contest showed how valuable that additional attacking dimension can be.
4. Milan’s set-piece preparation created a decisive advantage
Set-pieces were among the most important elements of this derby.
Milan scored twice from situations involving Moreira’s delivery: Pulisic’s opening goal followed a cross from the right, while Rabiot’s goal came directly from a corner.
Moreira then completed his extraordinary performance with a direct free-kick in the 43rd minute.
From approximately 25 yards, he curled the ball beyond goalkeeper Josep Martínez to restore Milan’s two-goal advantage.
It was a technically outstanding finish, but it also had enormous psychological significance.

Inter had gradually recovered from their disastrous start. Bastoni’s 22nd-minute header had reduced the deficit, and the visitors were beginning to threaten more consistently.
Maignan then produced a crucial save to deny Djed Spence from close range.
At that moment, Inter had an opportunity to build momentum and potentially equalise.
Instead, Moreira’s free-kick changed the mood again.
The goal ensured that Milan entered half-time with a two-goal cushion, forcing Inter to chase the match after the break.
There is also a historical dimension to Moreira’s achievement. Opta recorded his strike as only the third direct free-kick scored by a Milan player in the Derby della Madonnina since its data collection began in 2004–05.
The previous examples came from Andrea Pirlo in December 2007 and Theo Hernández in the January 2025 Supercoppa Italiana.
The Milan vs Inter result therefore demonstrated the value of set-piece quality in a match where open-play possession was not enough to determine the outcome.
For Chivu, the defensive questions are particularly uncomfortable. Inter conceded from multiple situations, including a corner and a direct free-kick, while also failing to prevent Moreira from creating the opening goal.
5. Maignan and Milan’s defensive discipline defeated Inter’s possession
Perhaps the most interesting tactical lesson came after Milan had established their lead.
Inter had more possession, more shots and significantly more corners. Sky Sports recorded 56.9% possession for Inter compared with Milan’s 43.1%. The visitors also attempted 19 shots against Milan’s seven.
Those figures show that Inter were not completely absent from the match.
They had periods of attacking pressure and created opportunities that could have changed the result.
However, Milan’s defensive organisation and Maignan’s goalkeeping helped prevent that pressure from becoming a comeback.
The goalkeeper’s reaction save against Spence after Bastoni’s goal was particularly important. Had Inter equalised, the tactical and psychological balance of the match could have changed dramatically.
Maignan also dealt with attempts from Çalhanoğlu and Sučić, helping Milan preserve their advantage.
The defensive performance was not simply about sitting deep and allowing Inter to attack. It required concentration, organisation and the ability to protect the most dangerous areas of the penalty box.
The official Serie A match report described Inter’s second-half attacking play as slow and predictable. Chivu attempted to change the situation by introducing Piotr Zieliński and Henrikh Mkhitaryan, followed later by attacking options Ange-Yoan Bonny and Pio Esposito.
But Milan responded with fresh players of their own, including Ardon Jashari, Davide Bartesaghi and Alphadjo Cissé.
The changes helped preserve the defensive balance while offering Milan the possibility of threatening on the counter.
This was an important part of Amorim’s management of the game. His team did not need to chase another goal recklessly. They needed to protect the advantage, close central spaces and prevent Inter from building sustained pressure.
The Milan vs Inter derby was therefore a demonstration of how a team can concede possession and still control the outcome through defensive discipline.
Inter’s problem: possession without enough decisive penetration
Inter’s defeat should not be explained by the scoreline alone.
The visitors had more of the ball, attempted more shots and won more corners. Those statistics indicate that they had the territorial advantage for significant periods.
But possession is only valuable when it creates high-quality opportunities.
Inter’s challenge was converting their control into goals.
After Bastoni’s header, the visitors had opportunities to make the match more difficult for Milan. Maignan’s save against Spence was a major turning point, while other attacking situations failed to produce the required finish.
The second half was particularly disappointing for Chivu’s team.
Despite introducing additional attacking players, Inter struggled to break down Milan’s defensive structure. Their passing and movement did not consistently create the spaces required to turn territorial dominance into a genuine comeback.
There is also a psychological concern.
The official Serie A report noted that Inter had already shown a tendency to concede an early two-goal advantage to opponents during the opening part of the season. Falling behind twice in ten minutes against a major rival made the problem even more damaging.
For a team competing for the title, slow starts and defensive uncertainty cannot become recurring habits.
Chivu must examine how his side responds when opponents attack aggressively from the opening whistle, particularly when the opposition targets the spaces around the wing-backs.
What the result means for the Serie A title race
The derby victory was important for Milan beyond local bragging rights.
Reuters reported that the win moved Milan to fourth place, four points behind leaders Lazio and Inter, who were level on 25 points after the result.
The victory also gave Milan a fourth consecutive derby win in all competitions.
That is a significant psychological achievement against a rival that had entered the fixture unbeaten in the league.
For Amorim, the result provides evidence that his team can adapt its approach to a major opponent and win without needing to dominate possession.
For Inter, the defeat is a warning rather than a reason to abandon their season’s ambitions. They remain among the leading contenders, but their defensive reactions and ability to respond to early setbacks deserve immediate attention.
The next challenge for Milan is consistency. A derby victory can energise a season, but the team must reproduce the same organisation and intensity against opponents who may defend deeper and offer fewer spaces.
Inter, meanwhile, must demonstrate that this defeat was an isolated setback rather than the beginning of a wider tactical problem.
Final verdict: Amorim won the decisive tactical moments
The Milan vs Inter derby was not a simple case of one team dominating every aspect of the match.
Inter had more possession and attempted more shots. Milan had fewer attacking opportunities but made their important moments count.
The difference came from five decisive elements: Amorim’s 4-4-1-1 structure, Moreira’s positioning and creativity, Rabiot’s advanced role, Milan’s set-piece execution and the defensive security provided by Maignan and his teammates.
Moreira deserves the headlines, but the collective performance deserves the credit.
Milan understood that the derby would not necessarily be won by controlling the ball. It would be won by attacking the right spaces, exploiting defensive uncertainty and remaining disciplined when Inter pushed forward.
That is exactly what they did.
For Inter, the defeat raises questions that Chivu cannot ignore. For Milan, it offers something even more valuable: proof that they can beat their greatest rivals through a clear tactical plan and ruthless execution.
Can Milan turn this derby masterclass into a genuine Serie A title challenge, or will Inter respond by showing that one defeat cannot derail their season?
