With only a few weeks remaining of the season, Chelsea are still competing on three fronts.
They are locked in a battle for a top-four place in the Premier League, while they also remain in this season's FA Cup, where they have a semi-final tie against Manchester City coming up.
Heading into the opening leg of this quarter-final at Stamford Bridge, it appears to be a tough one to call. Chelsea are unbeaten at home in their last 11 European matches, but Rubin Kazan have not lost away from home in the competition so far this campaign.
Meanwhile, Rubin are likely to include midfielder Bibras Natkho, who impressed for Israel last week during their international matches against Portugal and Northern Ireland.
Rubin Kazan: LDWWDW
Possible starting lineups
Chelsea: Cech; Bertrand, Terry, Luiz, Ivanovic; Mikel, Ramires; Mata, Oscar, Moses; Torres
Rubin Kazan: Ryzhikov; Navas, Kuzmin, Kaleshin, Ansaldi; Sharonov, Orbaiz, Eremenko, Karadeniz, Natcho; Dyadyun
