The ongoing saga surrounding AC Milan and Inter Milan’s quest for a new home has taken yet another unexpected turn. Both clubs now seem to be leaning toward building their future stadium on the historic grounds of San Siro, stepping back from previous plans to relocate to the outskirts of the city in San Donato or Rozzano.
At a recent event titled Il Foglio a San Siro, attended by key figures from both clubs—including Inter CEO Beppe Marotta and Milan President Paolo Scaroni—a bold new concept was unveiled: an entirely underground stadium.

The idea, presented by Davide Bruno of Ion Fund, is nothing short of radical. He described a “disappearing stadium,” buried beneath the earth, surrounded by vast green space. According to Bruno, the plan includes planting 20,000 trees, half a million flowers, and building 7 kilometers of walking paths and slopes. The goal? To harmonize sport and sustainability in a way never seen before.
“This is a revolutionary vision,” Bruno said. “Of course, some fans might be disappointed by the lack of visual spectacle, but we must think about the planet, about Italy, and about Milan’s future.”

While the proposal has raised eyebrows for its creativity, it’s also raised concerns. Estimated at €1.5 billion (excluding costs tied to the San Siro land itself), the project’s feasibility is being questioned by many, especially given its ambitious scale and unusual format.
Despite the skepticism, the underground concept may win favor among environmentalists, many of whom have opposed earlier stadium proposals. With its promise of vast green space, reduced urban noise, and a minimal visual footprint, it presents an eco-friendly alternative—albeit one that may prove difficult to bring to life.

For now, Milan and Inter’s stadium journey continues, filled with ambition, innovation, and more than a few twists along the way.
