Dimitar Berbatov's departure from Tottenham is expected to accelerate in the next 24 hours.
United are working on a deal for Berbatov and Spurs' belief that Barcelona are also monitoring the 27-year-old could move negotiations along on the eve of the Premier League season.
At the moment, there has been no announcement of a fee being agreed between Spurs and United, and Berbatov has been training in London.
