The Serbian defender is one of numerous senior figures at the club whose deals run out at the end of the season, with Rio Ferdinand, Patrice Evra and Ryan Giggs also among that number.
Vidic, given his contract situation, has several teams looking at him. Vidic is a very good player and will have no trouble finding a new club. For the time being we are remaining calm. However, at the moment, I would rule out an extension with Manchester United.
It's another crushing blow for the Red Devils, which have experienced a downward spiral since seeing David Moyes take over as the successor to Sir Alex Ferguson.
The retirements of dressing-room staples such as Paul Scholes and Gary Neville have already had a telling effect at the Theatre of Dreams in recent years, and this summer only promises to prolong the period of transition currently taking hold of the club.
It's nothing new for a Manchester United player to come so close to the end of his deal before penning new terms with the club; however, Martina's recent comments wouldn't appear very encouraging in Vidic's case.
The New York Times' Jerrad Peters recently voiced his opinion that, should Vidic leave, Milan would be a perfect fit for the defender:
In the figures of Phil Jones, Jonny Evans, Chris Smalling and the emerging Michael Keane, Moyes has a number of centre-backs waiting to step into any void should the 32-year-old exit this summer. There's just not a lot of pedigree considering those four players have an average age of just 23.
According to Manchester United's official website, Vidic has made more than 280 appearances for the Red Devils since arriving from Spartak Moscow in 2006, establishing himself as a fan favourite at the Theatre of Dreams.
During that time, the veteran has won five Premier League titles, a Champions League crown, one FIFA Club World Cup and three League Cups.
The official Premier League Twitter account recently paid tribute to the stalwart:
Jackson does go on to mention that Martina's words could be little more than an agent's tactic in order to find his client a better deal—far from unheard of in such situations.
Still, Vidic's departure would stand as another sign of how things are changing at United and not necessarily for the better.
