Leonid Slutsky will leave CSKA Moscow after the Wembley date with Tottenham and has already been linked with a move to Vitesse Arnhem.
Vitesse are owned by Russian Alexander Chigirinsky and are tightly bound with Chelsea, who send several young players each year to develop at the club.
Lewis Baker, Matt Miazga and Nathan are on loan in Arnhem this season, enjoying differing degrees of personal success.
Since manager Peter Bosz moved to Maccabi Tel Aviv in January and then onto Ajax, Vitesse has slipped down Eredivisie.
