Milan's Mayor Giuseppe Sala has publicly doubled down on the controversial sale of the iconic San Siro stadium to AC Milan and Inter Milan, dismissing accusations of procedural impropriety as "nonsense" even as nine individuals face criminal investigation for allegedly rigging the €197 million deal.
Timeline: How the Investigation Unfolded
To understand this controversy, it's essential to grasp the sequence of events:
• March 25 - April 30, 2025: The public tender was launched and closed. Claudio Trotta's "Sì Meazza" committee decided not to participate, citing the extremely tight 37-day deadline.
• November 2025: The city completed the sale of San Siro to AC Milan and Inter Milan for €197M. The transaction was finalized despite public opposition.
• March 2026: The Milan Public Prosecutor's Office conducted raids on city offices, the M-I Stadio management company, and suspects' homes—four months after the sale was already complete. Investigators seized phones and electronic devices from nine individuals.
• May 2026: The Milan Court of Review annulled some of those seizures, ruling that investigators had conducted exploratory searches before the prosecutor's office issued properly bounded search orders.
This timeline is critical: the criminal investigation began after the sale had already been finalized, meaning prosecutors were examining whether the tender process itself was rigged, not whether the completed sale should be reversed.
Why This Matters for Residents
For Milanese citizens and taxpayers, the sale and subsequent redevelopment of San Siro carries significant long-term consequences:
• Loss of public asset: After nearly nine decades of municipal ownership, the city has relinquished control over one of Europe's most storied sports venues. The €197M sale price will be used for other municipal priorities, but the land and future commercial development now rest entirely in private hands.
• Construction disruption: Preliminary work for the new stadium—including demolition of the south ticket office and environmental remediation—is already underway. Expect significant construction activity and traffic disruption in the San Siro district through 2031.
• Transparency concerns: The Italian Competition Authority (AGCM) has previously criticized Italian municipalities for opacity in stadium management contracts, urging adherence to public procurement rules. The ongoing criminal probe suggests Milan may have fallen short of those standards.
• Taxpayer risk: Even when stadium projects are billed as "privately financed," cities often bear hidden costs through tax breaks, infrastructure upgrades, and foregone revenue. Residents should scrutinize whether the municipality is subsidizing the clubs' new venue through indirect mechanisms.
Criminal Charges: Understanding Italian Law
The investigation focuses on two serious Italian criminal charges:
• Turbativa d'asta (bid rigging): This offense—explicitly protected under Italian public procurement law—carries penalties of 6 months to 4 years imprisonment and significant fines. It's treated as a particularly grave violation because it undermines the integrity of public tender processes and cheats taxpayers.
• Rivelazione di segreto d'ufficio (unauthorized disclosure of confidential information): This offense can result in 3 months to 2 years imprisonment. In the context of public procurement, it's viewed as compounding bid-rigging schemes by giving private parties unfair advantages through inside information.
Italian law treats these offenses with severity because they strike at the foundation of transparent public administration. The EU and Italian authorities view bid-rigging as a form of fraud against the state, harming not just the immediate transaction but public confidence in government integrity.
Speaking at a public ceremony, Sala defended the City of Milan's handling of the tender process, asserting that the municipal government was not legally required to hold a competitive bid at all. He directly challenged critics who claimed the 37-day bidding window was unreasonably short, arguing that any genuinely interested party could have requested an extension or filed a formal appeal—neither of which occurred.
The "Proroga" Dispute: Extension Rights Remain Unclear
A central point of contention is whether interested bidders could have actually requested a deadline extension (proroga). Sala's defense rests on this claim, but critical questions remain unanswered:
• Tender Documentation Gap: The article does not have access to the full tender documentation to confirm whether a formal proroga mechanism was explicitly outlined and communicated to potential bidders. Without seeing the tender rules of engagement, it's unclear whether extensions were genuinely available or merely theoretically possible.
• Trotta's Counter-Argument: Concert promoter Claudio Trotta, founder of the "Sì Meazza" committee advocating for stadium renovation rather than replacement, states explicitly that the 37-day period made it "impossible to participate." He noted that he and other entertainment operators had anticipated at least 120 days to prepare a viable bid. There is no public record of the city offering or granting any extension, nor evidence that requesting one would have been successful given the tight timeline already set.
• The Prosecutor's Hypothesis: Investigators are examining whether the tender specifications were deliberately designed as "tailor-made" for Milan and Inter—meaning the rules were crafted so that only the clubs could realistically meet them, making any extension irrelevant since genuine competition never existed.
Until the tender documentation is made fully public, residents cannot verify whether Sala's "proroga" defense is legally sound or a rhetorical deflection.
The Tender That Sparked a Criminal Investigation
The Milan Public Prosecutor's Office opened its inquiry after concert promoter Claudio Trotta filed a formal complaint. Prosecutors Giovanni Polizzi, Paolo Filippini, and Giovanna Cavalleri are examining whether the public tender process, launched on March 25, 2025, and closed on April 30, 2025, was designed with specifications that only the clubs could realistically meet, potentially violating public procurement principles.
The investigation centers on the hypothesis that there were undisclosed exchanges of information between municipal officials and club representatives that shaped the tender specifications and gave AC Milan and Inter unfair advantages.
However, in a significant setback for prosecutors, the Milan Court of Review annulled some of those seizures in May 2026, ruling that investigators had conducted exploratory searches of devices before the prosecutor's office issued a properly bounded seizure order with specific search criteria.
Who Is Under Investigation
The nine individuals named in the probe include:
• Giancarlo Tancredi and Ada De Cesaris, former city councillors
• Christian Malangone, director general of Palazzo Marino (Milan's city hall)
• Simona Collarini, former municipal department head
• Mark Van Huukslot, Giuseppe Bonomi, and Alessandro Antonello, former executives and consultants for the clubs
The charges being examined are turbativa d'asta (bid rigging) and rivelazione di segreto d'ufficio (unauthorized disclosure of confidential information). If proven, these offenses suggest that public officials may have coordinated with private parties to structure the sale in a way that excluded genuine competition, undermining the integrity of the public procurement system.
Sala's Defense and the Political Stakes
Mayor Sala has consistently maintained that Milan's municipal government acted within its rights and was under no obligation to hold an open tender. His most recent comments dismissed the controversy as politically motivated noise. "We are with our conscience more than clear," he stated, responding to criticism that the tender window was too brief.
His key argument: if Trotta or any other party truly wanted to participate, they should have requested a deadline extension or filed a legal challenge. The fact that neither action was taken, Sala contends, proves there was no serious alternative interest in acquiring the stadium.
The New Stadium and Olympic Commitments
Despite the legal and political turbulence, both clubs are moving forward with construction plans. The new stadium, to be built on land surrounding the current San Siro, is scheduled for completion by 2031. A formal environmental impact assessment—a mandatory step under Italian law—has been initiated by the city.
In the meantime, San Siro will remain operational. It is slated to host the opening ceremony of the Winter Olympics in February 2026, and both Milan and Inter will continue playing home matches there for at least the 2026-2027 season.
Five separate lawsuits filed by residents' associations and civic groups are pending before the Regional Administrative Tribunal (TAR) of Lombardy. A ruling is expected within approximately 60 days, which could delay or modify the redevelopment plans if the court finds procedural flaws in the approval process.
The Broader Context: Stadium Sales and Public Interest
The San Siro case is not unique. Across Europe, the privatization and redevelopment of publicly owned stadiums often provoke fierce debate over transparency, public benefit, and the balance between commercial interests and civic heritage. Economic studies consistently show that public subsidies for professional sports venues rarely deliver the promised economic gains and often impose a net cost on taxpayers.
The AGCM has emphasized that stadium management should be treated as a public service of economic relevance, requiring open competitive procedures and rigorous oversight. The Milan case, with its allegations of backroom coordination and tailor-made tender specifications, exemplifies the risks when these principles are not fully observed.
Sala's assertion that the city was not required to hold a competitive tender at all raises further questions. While Italian law may permit direct negotiations or limited tenders in certain circumstances, best practices in public administration favor transparency and competition to ensure the public interest is protected and taxpayers receive fair value.
What Happens Next
The Milan Prosecutor's Office is reportedly using 150 keyword searches to analyze communications seized from the phones of the nine suspects, seeking evidence of collusion and information-sharing that may have shaped the tender process. The investigation is ongoing, and formal charges could follow if prosecutors find sufficient evidence of criminal conduct.
Meanwhile, the TAR Lombardy decision on the five pending lawsuits will determine whether the sale and redevelopment can proceed as planned or if the city and clubs must address procedural deficiencies.
For now, San Siro stands as a symbol of the tension between sporting tradition, commercial ambition, and the accountability of public officials. Whether the stadium's sale will ultimately be remembered as a pragmatic solution or a case study in flawed governance depends largely on what prosecutors and judges uncover in the months ahead.
