Group B: PSV Eindhoven, Manchester United, Wolfsburg, CSKA Moscow
Manchester United finally have a tough group opponent now that Bundesliga runners-up Wolfsburg are in there with them. PSV has lost Georginio Wijnaldum and Memphis Depay, which could cost them when it comes to emerging from group play. If Manchester City buy Kevin De Bruyne away from Wolfsburg, that would create a huge hole there. For now, Man U and Wolfsburg should emerge. The first games come on September 15 as PSV has Man U and Wolfsburg has CSKA Moscow.
Group C: Benfica, Atletico Madrid, Astana, Galatasaray

Group D: Juventus, Manchester City, Borussia Moenchengladbach, Sevilla
Once more, City find themselves in another Champions League “Group of Death” with the Italian champions, the Europa League holders, and Germany’s third best team. Juventus and City should come out. On September 15, City play Juventus and Sevilla must deal with Borussia.
Group E: Barcelona, Roma, Bate Borisov, Bayer Leverkusen

Group F: Bayern Munich, Arsenal, Dinamo Zagreb, Olympiakos

Group G: Maccabi Tel Aviv, Chelsea, Porto, Dynamo Kyiv

Group H: Zenit St. Petersburg, Lyon, Valencia, Gent
Valencia qualified thanks to a playoff win over Monaco, and they are now in a competitive group. Gent shocked Belgium by winning their entry, and Lyon could legitimately challenge Zenit St. Petersburg who still have not made a big dent in the Champions League. Look for Zenit St. Petersburg and Lyon to qualify. September 16 will see Gent taking on Lyon and Valencia dealing with Zenit St. Petersburg.
