Juventus 2-1 FC Shakhtar Donetsk: Both clubs are in excellent form, but the Italian champions will expect to mark the first European match at the new Juventus Stadium with a victory.
FC Nordsjælland 0-2 Chelsea FC: After surrendering two points at home to Juventus, the defending champions should claim all three against the competition newcomers in Denmark.
Valencia CF 2-0 LOSC Lille: It has been a poor start to the season for both teams, but Valencia are traditionally a force at Mestalla and should kick-start their campaign with a win.
FC BATE Borisov 1-3 FC Bayern München: While the Belarusian title holders made a vibrant start in Lille, winning 3-1, Bayern are in magnificent, free-scoring form on all fronts and will take some stopping.
SL Benfica 1-2 FC Barcelona: Barça have looked more fragile than usual but are still getting results. Expect the Catalan giants to edge this Iberian derby in Lisbon – perhaps with another late winner.
FC Spartak Moskva 1-0 Celtic FC: Celtic do not travel well in Europe, but Spartak's home record in this competition is nothing special either. One goal could be enough for Unai Emery's side.
CFR 1907 Cluj 0-2 Manchester United FC: United won 2-0 in Romania last season, against FC Oţelul Galaţi, and though both teams go into the fixture with three points, the visitors are the more likely to double their tally.
Galatasaray AŞ 2-0 SC Braga: Both sides were defeated on matchday one but the Turkish champions will have been much happier with their performance and should make home advantage count in Istanbul.
FC Dynamo Kyiv 2-1 GNK Dinamo Zagreb: A 4-1 Ukrainian Cup defeat by FC Shakhtar Donetsk cost Dynamo Kyiv coach Yuri Semin his job, but a victory over the Croatian champions could spark a renaissance.
FC Porto 1-1 Paris Saint-Germain FC: Having both got off to a flier on matchday one, the teams will be eager to assume sole leadership of Group A with a win. It will probably end honours even.
FC Schalke 04 3-0 Montpellier Hérault SC: Opportunity knocks for Schalke to put six points between themselves and the French champions who are eager to prove they are not one-season wonders.
Arsenal FC 2-0 Olympiacos FC: This is the third season in four that the Gunners have hosted Olympiacos on matchday two. They won the previous two encounters and should complete the hat-trick.
RSC Anderlecht 1-1 Málaga CF: Two teams that came through the play-offs and achieved positive results in their opening group games meet in Brussels with little to choose between them.
FC Zenit St Petersburg 2-1 AC Milan: Massimiliano Allegri's side have made a disjointed start to the campaign and big-spending Zenit, smarting from a heavy defeat at Málaga, could add to the Italian club's woes.
Manchester City FC 2-2 Borussia Dortmund: Two teams who fell at the first hurdle last season before going on to win domestic championships have lofty ambitions in Europe this term, but victory here may prove elusive.
AFC Ajax 0-2 Real Madrid CF: José Mourinho's side won 3-0 in Amsterdam last season and, buoyed by their dramatic late win against Manchester City, should stroll to another straightforward victory.
