Tottenham face a battle to keep hold of coach Tim Sherwood amid interest from Blackburn Rovers.

Spurs manager Andre Villas-Boas refused to be drawn on the subject after his side's 3-2 win at Manchester United.

"I can't comment on the Blackburn situation because I have Steve Kean as a friend and I respect him," said Villas-Boas.

"But if Tim is a candidate, he has to make a personal decision and speak to the club."
