Originally there were discussions about constructing a new ground in the area of the teams' current home at San Siro.
"Milan confirmed their desire to proceed with La Maura," Sala said after a meeting with club officials, referring to an area that is home to a harness-racing track and is not far from San Siro.
"Being as we have a formal discussion open about a new stadium near San Siro, what I said is that, if they do not intend to proceed, they should formally say so.
"I told them that I have taken note of their interest (in the La Maura site) but what is needed is a project."
He said the club told him that they will get back to him in two weeks with the outline of a new project.
With Milan looking set to go it alone, Inter have reportedly got a plan B ready after identifying a site near the city, between the towns of Assago and Rozzano, as an area where they could build a new ground.
This would be near the Assago Forum that is home to the Olimpia Milano basketball team.
Should they both build new stadiums, the iconic San Siro would be saved from demolition but would be without a tenant.
