Inter and Milan have reportedly already decided that they will end cohabitation at San Siro, with the Rossoneri to move out by 2017.
Whilst the Nerazzurri have in previous years been working on a plan to move away from the Giuseppe Meazza stadium to build their own ground, recent reports have suggested it has been Milan pushing forward with such plans under Barbara Berlusconi’s guidance.
Speculation today is that the Diavolo have been working over the past six months on plans for a new stadium to be constructed six kilometres to the north-west, where the Fiera Milan exhibition is currently based and where Expo 2015 will be held.
Arexpo, formed by city authorities to buy up the area of land and oversee its development from 2015, confirmed in November Milan’s initial interest.
They have set a deadline of March 13 - latest March 14 - for proposals to be put forward for construction of a stadium on the land, planned as part of a wider multi-sports and functions development.
SportMediaset and Il Giorno say that Milan are going to come forward, with an aim to begin construction at the end of Expo 2015, in the autumn of that year, and have work completed in time for the 2016-17 season, although it may be more likely that the team cannot move in until the following year.
The Rossoneri and Inter are also seen as in agreement to end their sharing plan at San Siro, with Milan expected to confirm their plans over the course of the next month in time for Arexpo's deadline.
Inter, in turn, are speculated as favouring staying at the stadium and carrying out renovation work.
The two Milanese giants have shared the Giuseppe Meazza since the 1947-48 campaign. The ground will host the 2016 Champions League Final.
