Nemanja Vidic is chasing a massive new contract at Manchester United.

The People says Vidic is looking to get a hike to the £130,000-a-week bracket to keep him sweet.

Vidic is under contract until the summer of 2012 but his camp feels he has now become the main man at the back and deserves a major improvement in his terms.

The defender was happy to pen a deal worth around £75,000-a-week - or £4million-a-year - in November 2007 But Ferdinand's injury problems and recent loss of form have left Vidic as the key player at the back for Ferguson, and the player's shrewd handlers see their chance to get more cash from United.
