"We have made Tottenham an offer on Berbatov and we have good expectations that this deal will go through," the Scottish boss was quoted as saying by Sky Sports.

"Berbatov has been impressive during a long time and would be a great addition to our attack."

United, who clinched the Premiership and the Champions League titles last season, have been long-term admirers of the Bulgarian hitman.

Berbatov has impressed for Spurts since joining from Bayer Leverkusen in the summer of 2006.
