Munich - UEFA Champions League Group E winners FC Bayern München's unrelenting desire for victory will be put to the test against PFC CSKA Moskva on Wednesday (kick-off 19:45 GMT / 20:45 CET). has the pre-match skinny on the Bundesliga leaders' final European assignment of the calendar year...

With top spot in the bag, Bayern could be forgiven for taking their foot off the gas on Matchday 6. Momentum and UEFA coefficient rankings points are nevertheless two prizes worth fighting for against a CSKA side who can still reach the knockout stages with a win at the Allianz Arena, depending on the outcome of Manchester City FC's trip to AS Roma.

(r.) is expected to make his first competitive start of the season, having been restricted to just four substitute appearances after aggravating a persistent knee problem during pre-season. Pierre-Emile Hojbjerg and Xherdan Shaqiri are also in contention, but Moroccan centre-back Medhi Benatia is suspended.

Swedish midfielder Rasmus Elm (l.), who is yet to make an appearance this season, remains sidelined with a longstanding stomach injury, while Alexei Berezutski is rated as doubtful. Head coach Leonid Slutsky otherwise has a fully fit squad to choose from.

With a handful of fringe players likely to take to the field, 's presence and experience as the last line of defence will be key in the opening stages. The 2014 FIFA Ballon d'Or nominee has rewritten the goalkeeper's handbook in recent seasons and has already kept 14 clean sheets in 22 appearances in 2014/15.

Seydou Doumbia struck twice in a famous victory over Man City on Matchday 4 to take his 2014/15 Champions League tally to three goals in five starts. The Ivorian international had chances against Bayern on Matchday 2 and it's his performance that could make all the difference to the Russian club's final standing in the group.

(Bayern defender): "Why should we take our foot off the gas? We're at home and want to sign off the group phase with a win."

Leonid Slutsky, CSKA coach (on leaving Seydou Doumbia out of the starting XI on Sunday): "[Doumbia] was carrying an ankle knock. If he had played, it's unlikely he would have been able to play in Munich."

Man City inflicted a first defeat on Guardiola's side since the 2-0 loss to Borussia Dortmund in the Supercup. Bayern have since picked up back-to-back 1-0 wins over Hertha Berlin and Bayer 04 Leverkusen, with CSKA also victorious in all three of their league outings following Matchday 5's 1-1 draw with Group E rivals AS Roma.

Thomas Müller's first-half penalty settled matters in Moscow on Matchday 2, after Bayern won both group encounters in last season's competition. The Bavarians' home record against Russian opposition (W4, D3, L1) stands in stark contrast to CSKA's, the Red Army having lost all three of their previous outings on German soil.

Possible line-ups:

FC Bayern: Neuer - Rafinha, J. Boateng, Dante, Juan Bernat - Höjbjerg, Schweinsteiger, Rode, M. Götze - Shaqiri, Lewandowski

CSKA Moskva: Akinfeev - Mario Fernandes, V. Berezutskiy, Ignashevich, Shchennikov - Wernbloom, Natcho - Tosic, R. Eremenko, Musa - Doumbia
