Agent reveals Man Utd's Berbatov eager to hear from Anzhi
The Bulgarian, 30, is likely to be offloaded in January with his contract running out next summer.
Galatasaray have also shown strong interest but his agent Emil Danchev said: "We would be interested when Anzhi make a concrete offer.
"We will sit down with Dimitar and ponder this. I don't know if Dimitar is happy in Manchester. He plays, then he just sits on the bench."
