Dynamo Moscow director Dmitry Gafin has admitted young midfielder Arsen Zakharyan could seal his move to Chelsea in January.
The Blues attempted to sign the 19-year-old during the summer transfer window but complexities involved in dealing with a Russian club left them unable to complete a deal for Zakharyan before the window closed.
Since then, sources have informed 90min that Chelsea have not given up on Zakharyan, who comes with a release clause of around £12.6m, and have remained in contact with all relevant authorities in an attempt to conclude a transfer.
Talks have been held between Chelsea and FIFA, UEFA and the Premier League to try and find a way to work within the current rules regarding dealing with Russian clubs, with Blues co-owner Todd Boehly still very keen to get a deal done.
In Moscow, club director Gafin has conceded that talks with Chelsea could reignite in January.
"We cannot rule out the resumption of history with Chelsea in winter, I cannot comment on the information that appears and will appear," he told TASS.
Gafin was, however, quick to question claims that Zakharyan has already agreed personal terms with Chelsea, insisting Dynamo Moscow have not given the club permission to speak with the Russia international just yet.
"Regarding his alleged contract with Chelsea, we don't know anything about this, we did not give permission for such contacts," he said. "I think this is from the rumour mill."
