CSKA Moscow have made an inquiry into the availability of Chelsea midfielder Marko Marin, with the Russian Premier League leaders keen to take the German international on loan.
Marin has struggled to force his way into the Chelsea team this season after arriving at Stamford Bridge in the summer from Werder Bremen.
And CSKA could offer him an escape route to Moscow, having contacted Roman Abramovich about Marin's availability, according to Russian newspaper Izvestia.
CSKA have a good relationship with Abramovich dating back to mid-2000s, when the Russian billionaire's oil company Sibneft sponsored the club's shirts.
And Marin's agent Fali Ramadani has fuelled speculation by admitting that several clubs from across Europe are interested in signing his client.
"I will not hide the fact that Marin has several interesting offers of a loan until the end of the season," he told Izvestia.
"I cannot name clubs, but I can say that the offers come both from Western and Eastern Europe.
"Marko wants more playing time, but we understand that at a major club like Chelsea there will always be serious competition for places.
"Marin feels good in London but in order to play regularly for the German national team he needs to be a first-teamer.
"We'll have a conversation soon with the Chelsea hierarchy about all possible options for him to continue his career."
23-year-old Marin has made just eight first-team appearances in all competitions at Chelsea.
