Inter Milan and AC Milan set for new stadium
The two clubs are said to be close to announcing a joint partnership to build a new stadium next to the iconic San-Siro, then demolish the old stadium.
"A stadium is a very important asset in modern football," Antonello told Sky Sports.
"We are working together at San Siro stadium and shortly we will tell Milan's mayor about our decision.
"We are hoping to get collaboration (with AC Milan and Milan authorities)."
The San Siro, also known as Stadio Giuseppe Meazza, was opened in 1926.
