Manchester United boss Sir Alex Ferguson is reviving his interest for Tottenham fullback Gareth Bale.

The News of the World says the move is sure to spark another row with Spurs after the long battle over Dimitar Berbatov.

Despite injury since arriving at White Hart Lane from Southampton, Wales international Bale, 19, has been checked out by the Old Trafford scouts.

Bale was signed for £5million from Saints in a deal which could rise to £10m. In August he extended his Spurs deal by four years.

United may make their move in January, with realistic hopes of clinching a deal next summer.
