Dimitar Berbatov's agent has hinted that the Fulham striker could leave the club for Russia in the summer.

Emil Danchev believes the Russia Premier League is "growing seriously" but insists that no formal offer has come for the 32-year-old.

"I have heard of interest from Russian clubs," ESPN quotes him as saying. "The Russian league is growing seriously, and should soon become one of the leading championships in Europe - so to play in that country would be interesting.

"Of course, much will depend on the decision of the Fulham hierarchy. But at the moment I do not know of any formal offers."

Berbatov has scored 13 goals in the Premier League for Fulham this season.
