Manchester United defender Nemanja Vidic is becoming tired of constant transfer speculation according to his agent Silvano Martina.

The Serbia international has been linked with AC Milan, Barcelona and Real Madrid in recent times but insists he is happy at Old Trafford and his agent has echoed those thoughts, saying transfer gossip is growing old.

"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."
