Group A: Manchester United, Shakhtar Donetsk, Bayer Leverkusen, Real Sociedad - it will be a tough battle between Shakhtar and Sami's team to qualify. I'm sure United will qualify, but I wouldn't be surprised if they only got 2nd place, mainly because Moyes is a novice in CL.
Group B: Real Madrid, Juventus, Galatasaray, FC Copenhagen - boring. 2 friendlies between the giants and easy qualification
Group C: Benfica, Paris St-Germain, Olympiakos, Anderlecht - by far the weakest group. PSG should stroll it.
Group D: Bayern Munich, CSKA Moscow, Manchester City, Viktoria Plzen - CSKA has a decent record in Europe and they are tough to beat, Man City are favorites, but it might be harder than they expect. Bayern will win the group easily, of course.
Group E: Chelsea, Schalke, FC Basel, Steaua Bucharest - boring and uninspiring
Group F: Arsenal, Marseille, Borussia Dortmund, Napoli - the group of death. Dortmund will qualify for sure and I would bet on Rafa over Wenger.
Group G: FC Porto, Atletico Madrid, Zenit St Petersburg, Austria Vienna - no big names, but a lot of quality and ambition in this group. Austria are outsiders, the rest is completely unpredictable.
Group H: Barcelona, Milan, Ajax, Celtic - Barca seems to play these teams every year, but I actually like this group - lots of little side-plots here and every team presents a very different challenge for Barca. Milan is inconsistent, so Ajax and Celtic have chances to qualify.

For the by far the most interesting groups will be A and F and I might also watch some games from groups D and H. Don't really care about the rest.
