The statistics behind Milan’s defensive decay
AC Milan conceded 49 goals in the 2023-24 Serie A campaign. This was not a minor leak; it was a systemic failure that left them nineteen points behind champions Inter. While their rivals built a Scudetto on defensive solidity, Milan spent the season caught in transitional chaos.
The numbers from the subsequent campaigns show only marginal improvements. The lack of a ball-playing center-back has stalled their build-up play, forcing midfielders deep and isolating the front line. It is this tactical stagnation that makes the interest in Sporting CP's Goncalo Inacio so compelling.
According to reports, Milan are preparing a new attempt for Inacio as the Portuguese club's valuation becomes more realistic. If Milan want to transition from a chaotic transition team to a controlled, possession-dominant side, the Portuguese defender is the exact profile they need.
The ball-playing profile Milan desperately lacks
Inacio is not a traditional Italian defender who thrives on low-block clearance work. He is a modern progressor of the ball, averaging 7.43 progressive passes per ninety minutes over the last year in Portugal. For context, Fikayo Tomori managed just 3.78 progressive passes per ninety, while Malick Thiaw hovered at 3.12.
This delta of over three progressive passes per game changes how a team can bypass the first line of pressure. When opponents press Milan in a mid-block, they focus on blocking passing lanes to the central midfielders. With Inacio on the pitch, his ability to hit line-breaking passes directly to the left winger or attacking midfielder bypasses this trap entirely.
His long-passing metrics are equally elite. Inacio completes 68.4% of his attempted passes longer than thirty yards, compared to Tomori’s 51.3% and Thiaw’s 48.9%. This means Milan can transition from build-up to attack in a single action, utilizing Rafael Leao’s pace on the counter-attack more efficiently.
Furthermore, Inacio operates comfortably in the half-spaces. In Sporting's three-back system, he frequently carried the ball into the midfield third, recording 1.84 progressive carries per ninety minutes. Milan's current center-backs combine for less than 0.9 progressive carries per ninety, making their possession play predictable and slow.
The tactical evolution under Paulo Fonseca
Milan's shift from Stefano Pioli's man-oriented, high-pressing defensive style to Paulo Fonseca's possession-oriented, positional structure demands different qualities from their center-backs. Pioli's system left huge spaces in midfield, forcing defenders into high-risk individual duels. Under that regime, Milan faced 12.8 shots per ninety last season.
Under Fonseca, the team wants to control games through possession, targeting a pass completion rate of over 87% in the opposition half. Inacio's passing accuracy of 89.1% overall, and specifically 92.4% in the defensive third, aligns perfectly with this possession-based style. He does not panic under pressure.
His presence would allow Milan to build up in a 3+2 structure. In this shape, Inacio can slot into the left-sided center-back role, allowing Theo Hernandez to push higher up the pitch. This creates a natural overload on the left flank, which has always been Milan's primary attacking outlet.
It also reduces the burden on Tijjani Reijnders. Last season, the Dutch midfielder had to drop deep to collect the ball from the center-backs. With Inacio carrying those playmaking duties, Reijnders can position himself ten yards higher, where his creativity is far more dangerous.
The progressive passing network of Goncalo Inacio
Let's look at where Inacio's passes actually go. His distribution is not limited to safe, sideways passes to his defensive partner. He completed 142 passes into the final third last season, whereas Tomori completed 78.
His ability to execute the diagonal switch to the right flank is particularly useful. Inacio averaged 2.4 switches of play per ninety minutes for Sporting CP. This long-range accuracy can isolate Samuel Chukwueze or Christian Pulisic in 1v1 situations on the right wing.
Milan's current build-up pattern is heavily biased toward the left. This left-side dominance makes them easy to defend, as opponents simply tilt their defensive block to that side. Inacio’s ability to switch play balances the attack, forcing opponents to stretch their defensive lines.
Analyzing the defensive trade-offs in a back-four system
However, this statistical profile comes with significant defensive caveats. Inacio has played almost exclusively in a back three under Ruben Amorim at Sporting. Transitioning to a back four requires a different set of spatial awareness and physical demands.
The aerial and ground duel deficit
In duel situations, Inacio's numbers drop from elite to concerning. He won only 54.2% of his aerial duels last season, a figure that ranks in the bottom third of central defenders in Europe's top leagues. In Serie A, where physical forwards like Duvan Zapata or Romelu Lukaku thrive on isolating defenders, this weakness will be targeted.
Tomori, by comparison, wins 62.1% of his aerial duels, while Thiaw leads Milan's defensive unit at 64.5%. If Inacio is paired with a passive partner, Milan's vulnerability on set pieces and crosses will increase. They already conceded eleven goals from set-piece situations last season, and Inacio does not solve this issue.
Ground duels present another area of risk. Inacio averages only 1.12 tackles per ninety minutes, preferring to drop off and intercept passes. His 1.45 interceptions per ninety show good reading of the game, but his tackle success rate when dribbled past is just 47.1%.
The recovery pace equation
Inacio also lacks the raw recovery pace of Tomori. Tomori's recovery speed allows Milan to play a high defensive line with an average defensive line height of 52.4 meters. If Inacio is paired with a slow partner like Matteo Gabbia, Milan's backline could be exposed by rapid counter-attacks.
The financial reality of the deal
Sporting initially demanded the full value of Inacio's release clause, which stood at sixty million euros. However, the financial dynamics in Lisbon have shifted, and reports suggest a deal could be struck around 35 million euros. This price point represents a significant market opportunity for Milan.
Compare this to other left-footed center-backs in the market. Arsenal paid over forty-five million euros for Riccardo Calafiori, while Alessandro Bastoni is valued well north of seventy million. At the lower price point, Inacio provides Scudetto-level build-up play at a mid-tier price.
Milan's transfer strategy under their current ownership has focused on statistical value. By identifying Inacio's passing volume as a tool to unlock their stalled offense, they are applying the same analytical framework that brought them Christian Pulisic and Tijjani Reijnders.
A symbolic return to structure and form
This shift toward tactical structure matches what is happening off the pitch at Casa Milan. The club is reportedly moving away from their streetwear partnership with Off-White. They are choosing to return to traditional formal dresswear next season, as discussed in the report on Milan's return to formal dresswear.
This return to classic tailoring runs parallel to their marketing focus for the new season. The slogan for the new away kit unveiling, "After Istanbul there's always Athens," recalls a time when Milan defined European tactical discipline.
If Milan want to replicate the defensive solidity of their historical championship teams, they cannot rely on chaotic transition battles. They need a defender who can control the tempo of the game from the back line. Goncalo Inacio has the statistical profile to provide that control, even if he requires a physical partner to mask his aerial deficiencies.
