The Champions League returns Tuesday with a matchday-two slate stacked with heavyweight ties, headlined by Manchester City against Paris Saint-Germain at the Etihad on Wednesday night.

PSG arrive as two-time holders on an 11-match unbeaten run in the competition after opening with a 6-1 demolition of Slovan Bratislava. City, 2-0 winners at Porto on matchday one, sit top of the Premier League. The subplots write themselves: Erling Haaland has 59 goals in 59 Champions League appearances and can break the record for the most goals in a player's first 60 games in the competition, while Gianluigi Donnarumma faces the club he left in the summer.

Tuesday's marquee tie takes Barcelona to RAMS Park to face Galatasaray. Barça opened with a 5-1 thrashing of Feyenoord and have not lost to the Turkish giants since 2011; Gala, beaten 3-1 at Sporting on matchday one, will lean on one of Europe's most intimidating home atmospheres to respond.

Elsewhere, Atlético de Madrid host Manchester United with the Spaniards needing a response after losing at Anfield, Roma face Real Madrid, Arsenal travel to Lille after a clean-sheet win in Naples, and Aston Villa meet Fenerbahçe. Bookmakers make Barcelona the narrow outright favourites at 4/1, just ahead of PSG, Bayern Munich, Arsenal, Real Madrid and Manchester City.
