The Russian Football Union (RFU) stressed Fabio Capello remains under contract with the national team.
Shakhtar Donetsk claim there has been no approach from Liverpool for in-demand midfielder Henrikh Mkhitaryan.
The 24-year-old, who can feature at left-back or centre-half, has left Falkirk on a Bosman free transfer.

He will compete with Callum Davidson for the left-back berth at McDiarmid Park.
