The 31-year-old defender has been identified by manager Massimiliano Allegri as the man to partner Philippe Mexes at the heart of the Serie 'A' giants' defence, and is ready to firm up interest in the Serbia international's signature.
Vidic has been plagued by injury over the past couple of seasons at Old Trafford, and was restricted to less than 20 first-team appearances for Manchester United last season, after missing the majority of the 2011/12 campaign.
Despite recently commenting that he is looking forward to working under new manager David Moyes, Vidic's future could in fact lie away from the reigning Premier League champions.
After Rio Ferdinand's decision to retire from international football - in an attempt to prolong his club career - Manchester United could conceivably entertain offers for Vidic, given their array of central defensive options.
Jonny Evans, Phil Jones and Chris Smalling have all proven competent deputies for first-choice pairing Ferdinand and Vidic, and there has even been suggestions that Moyes wants to add a new centre-back to his inherited squad this summer.
A move to Italy might be Vidic's best chance of guaranteed football in 2013/14, with the San Siro an attractive proposition given that he would still be able to test himself in the Champions League next year.
