Nemanja Vidic has sought to play down speculation about his future by insisting he is happy at Manchester United.

The Serbian has spoken out after recent comments credited to his agent Paolo Fabbri claimed he was angling after a move to Barcelona.

Vidic, who was one of United's key players in their Barclays Premier League title defence last season, made his first start of the season in Saturday's 5-0 win over Wigan after recovering from injury.

"I've never said anything about Barcelona or Real Madrid or AC Milan - or any club," he said.

"I never speak about my future so I don't know why someone else does. I showed at Wigan on the pitch how happy I am at this club.

"Any fan of United only has to see how I played to know how committed I am. I spoke with my agent about this and what he said. I know about all the rumours about me but I don't want it to have an impact on the club.

"It's not a good time for my club to be hearing those rumours," added the 27-year-old in reference to the summer departures of Carlos Tevez and Cristiano Ronaldo.

Vidic also dismissed as untrue reports his wife, Ana, has not settled in Manchester.

"It's not true that my wife is not happy," he continued. "I don't know how that rumour came out, she's not what you'd call a famous wife. She's never spoken to a newspaper."
