Tottenham remain concerned of losing Dimitar Berbatov to Manchester United in January.

The People says Berbatov's massive price tag and lack of form this season may cool United's interest. United boss Sir Alex Ferguson had switched his attentions to Jermain Defoe, but Spurs will not let Berbatov and Defoe leave together.

Berbatov would be keen to move to Manchester City instead as his close friend and fellow Bulgarian Martin Petrov is there.
