5-time champs L'pool back

Arsenal will be looking to win in Dortmund for the second season running, while the opening night of the Champions League group stage also sees Liverpool's return and last season's runners-up Atletico Madrid in action.

JUVENTUS V MALMO
Under previous coach Antonio Conte, Juventus failed to reproduce their dominant domestic form in Europe so Massimiliano Allegri will know the importance of beginning with a win against Malmo in Turin. The Italian champions, who will be without injured midfielder Arturo Vidal, are fresh from beating Udinese 2-0 on Saturday.

OLYMPIAKOS V ATLETICO MADRID
Spanish champions and last season's Champions League runners-up Atletico begin their campaign away to the Greek titleholders at the Georgios Karaiskakis Stadium. Atletico will be buoyed by avenging their 4-1 defeat to Real Madrid in May's final in Lisbon by winning 2-1 at the Santiago Bernabeu on Saturday.
Atletico coach Diego Simeone serves a one-game European touchline ban for storming onto the pitch to confront Real defender Raphael Varane towards the end of the Champions League final.

LIVERPOOL V LUDOGORETS RAZGRAD
Five-time European champions Liverpool mark their return to the Champions League for the first time since 2009 at home to the Bulgarian champions, who are making their group stage debut. Daniel Sturridge is injured for Brendan Rodgers's side but Raheem Sterling will return to the line-up.  

REAL MADRID V FC BASEL
Carlo Ancelotti's reigning European champions will be looking forward to the distraction of the Champions League after a poor start to the season domestically, with Saturday's 2-1 loss to Atletico in the Madrid derby their second in three games in La Liga. Ancelotti has yet to find a balance to his side following the summer arrivals of Toni Kroos and James Rodriguez, while goalkeeper and captain Iker Casillas's place in the team has been the subject of intense scrutiny.

BENFICA V ZENIT ST PETERSBURG
Portuguese champions Benfica, last season's beaten Europa League finalists, face a familiar foe as Zenit St Petersburg head to Lisbon coached by Andre Villas-Boas.  

MONACO V BAYER LEVERKUSEN
When they finished second in Ligue 1 last season, Monaco looked capable of going on to be a force to be reckoned with in Europe, but James Rodriguez, Radamel Falcao and other stars left over the summer without being replaced and Leonardo Jardim's side are in the relegation zone at home ahead of their meeting with early Bundesliga leaders Bayer Leverkusen. Roger Schmidt's visitors are without captain Simon Rolfes for the trip to the principality but Lars Bender is fit again and South Korea's Heung-Min Son is likely to start.

BORUSSIA DORTMUND V ARSENAL
Dortmund and Arsenal meet in the Champions League for the second season running. Last time around, the German giants won 2-1 in London, but an Aaron Ramsey goal handed the Gunners a 1-0 victory at the Signal Iduna Park. Arsene Wenger's side will be looking for a repeat performance here that would extend their unbeaten start to the campaign, although they must do without the injured Mathieu Debuchy.

GALATASARAY V ANDERLECHT
Turkish giants Galatasaray entertain Anderlecht looking for a better start to this season's Champions League than 12 months ago, when they were thumped 6-1 by Real Madrid in Istanbul. Now coached by former Italy boss Cesare Prandelli, Gala should do better against Anderlecht, even if the Belgian champions are so far unbeaten this season.
