AC Milan and Inter Milan have revealed two shortlisted designs for a new 60,000-seat stadium next to their iconic San Siro home.
The plans include renovating the San Siro area and the clubs have submitted a feasibility study to their municipality.
The new stadium is expected to cost 650m euros (£576m) and take three years to build.
The club also plan to consult fans about the proposals.
“AC Milan and FC Internazionale have shared a stadium in San Siro for more than 70 years,” said AC Milan chairman Paolo Scaroni.
