Nemanja Vidic vows to prove his commitment to Man United

Star defender Nemanja Vidic has vowed that he will prove his commitment to Manchester United with his performances in the coming weeks.

Vidic's advisor Paolo Fabbri was quoted last week as saying that the centre-back would welcome a switch to Barcelona.

It set alarm bells ringing at Old Trafford, as Vidic has become one of Europe's top defenders since joining three years ago. His wife was also reported as being unhappy in Manchester.

But Vidic insists he is focused only on United's title defence and Fabbri denied making the comments.

"I've never said anything about Barcelona, or Real Madrid or AC Milan - or any club. 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," The Sun quoted Vidic, as saying.

The 5-0 win at Wigan on Saturday was Vidic's first game back after an ankle injury.

He spoke to Fabbri about the story to voice his concern at the timing of it, after United lost Cristiano Ronaldo and Carlos Tevez.

"I don't want it to have an impact. I'm here and committed. I'll show that with how I play. It's not true that my wife is not happy. 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," he added.
