Lokomotiv Moscow host Bayer Leverkusen tonight with both sides' Champions League hopes hanging by a thread in Group D.
Leverkusen's superb 2-1 victory over Atletico Madrid on matchday four has given Peter Bosz's side hope of pushing for second place - but they must realistically win their remaining two games to stand any chance.
As for Lokomotiv, a 2-1 home defeat by Juventus leaves them four points off second-placed Atletico.
The lay of the land effectively turns this match into a shootout for the chance to catch Atletico - and with Diego Simeone's side taking on Juve in the other game, Lokomotiv and Leverkusen will both be hoping for a favour from Juve.
