Nemanja Vidic's agent has quashed speculation the Manchester United defender will leave Old Trafford this summer.

The Serbia international has been linked Barcelona, AC Milan and Inter Milan amid reports his family are unsettled in Manchester.

However, the player is under contract at Old Trafford until 2012 and his agent Silvano Martina believes he will stay put.

"Even though Vidic has not spoken for the last three months, there have been false interviews published in the press," Martina told Gazzetta dello Sport.

"I read that he wants to leave, that his wife is not happy at Manchester but all of these stories are false.

"He is very annoyed and saddened by these stories that give the wrong impression.

"In football you never know what can happen, but I believe he will remain at Manchester United, one of the strongest clubs in the world.

"If Vidic or I should have problems with the club (United), we will talk directly to Alex Ferguson and not to the newspapers."

Vidic joined United in January 2006 after two years at Spartak Moscow.
