Champions League – Group A

Who will triumph in the battle of the group’s giants — Real’s Cristiano Ronaldo, who has been courted by PSG, or the French club’s Zlatan Ibrahimovic? Wednesday, October 21: Malmo FF v Shakhtar Donetsk Paris St-Germain v Real Madrid

Group B

It’s all to play for — one win apiece — as Manchester United face CSKA in Moscow. But are Wolfsburg distracted by the scandal involving their backers Volkswagen? Wednesday: CSKA Moscow v Manchester United VfL Wolfsburg v PSV Eindhoven

Group C

Atletico will expect to beat outsiders FC Astana. Benfica are in form and their Argentina defender Nicolas Gaitan, often linked with a move to England, has been key. Wednesday: Atletico Madrid v FC Astana Galatasaray v Benfica

Group D

The second qualifying spot looks a straight fight between Sevilla and City, who will be without leading scorer Sergio Aguero.

Wednesday:

Manchester City v Sevilla Juventus v Borussia Moenchengladbach

Group E

Without Lionel Messi, Barcelona will rely on Luis Suarez (right) to put away Borisov. Roma hope Edin Dzeko is fit to make an impact against Leverkusen.

Tuesday, October 20: BATE Borisov v Barcelona Bayer Leverkusen v Roma

Group F

Arsenal started with two defeats and they can’t afford to lose at home to Bayern. That won’t be easy up against Europe’s most in-form striker, Robert Lewandowski.

Tuesday: Arsenal v Bayern Munich Dinamo Zagreb v Olympiakos

Group G

Jose Mourinho controversially left skipper John Terry out of Chelsea’s defeat by Porto so his selection against Dynamo Kiev will be particularly fascinating.

Tuesday: Dynamo Kiev v Chelsea FC Porto v Maccabi Tel Aviv

Group H

Zenit are top despite Andre Villas-Boas receiving a sixmatch ban for striking an official. Valencia with assistant manager Phil Neville are also in good shape to qualify.

Tuesday: Valencia v Gent Zenit St Petersburg v Lyon
