Berbatov double downs Black Cats

Dimitar Berbatov scored twice as unbeaten Manchester United powered on at the top of the Barclays Premier League with a 2-0 win over Sunderland.

The Bulgarian provided his side with a flying start when he nodded home Wayne Rooney's far-post cross after four minutes.

But Berbatov required a hefty deflection off Anton Ferdinand to net his 13th goal of the season.
