Nemanja Vidic's agent admits the Manchester United defender is becoming 'tired' of speculation linking him with a summer move away from Old Trafford.
Reports in the media have claimed that the Serbia international and his family have found it hard to settle in England since joining the North West club in 2006.
UEFA Champions League opponents AC Milan and Spanish giants Real Madrid and Barcelona have all been linked with Vidic's services, however Italian representative Silvano Martina insists any such links have been fabricated.
"There is nothing true in these reports. Me and Nemanja are becoming tired of such rumours," he told calciomercato.com.
"He still has two-and-a-half years left on his contract and he's not for sale."
