Manchester United captain Nemanja Vidic will leave the Premier League club at the end of the season.
Triumphs
While Moyes has spoken about the positive influence Vidic still has at United and indicated he wanted him to stay, it is not thought he was offered an extension and he has now decided to move on.
Vidic is free to talk with clubs outside England under the Bosman regulations, with Inter believed to be one of the front-runners to acquire his services.
The 32-year-old has been one of the most popular members of the Red Devils' squad since he arrived from Spartak for £7million - a transfer bizarrely announced on Christmas Day in 2005.
He has played a central role in virtually all United's significant triumphs since then - Vidic did recently reveal he handed his first winners' medal from the 2006 Carling Cup to Giuseppe Rossi as the Italian had played in all the previous matches up to the final.
Last May, Vidic skippered United to their historic 20th championship - his fifth and the last under Sir Alex Ferguson.
However, the tough defender made only 19 league appearances as he battled to overcome a serious knee injury, suffered in a Champions League defeat to Basle in December 2011 that required two major operations, ruling Vidic out for extended periods on both occasions.
The Champions League triumph over Chelsea at the Luzhniki Stadium in 2008 remains the high point of Vidic's entire career, given he subsequently featured in the final defeats to Barcelona in both 2009 and 2011, by which time the former Red Star Belgrade man had been elevated to captain.
Vidic's overall contribution is underlined by his presence in the PFA Premier League team of the season on four occasions and the FIFPro World XI twice.
