Well my summarisation for all the groups are.
Group A. Bayern Munich ,Man City ,Napoli ,Villarreal, I think both bayern munich and city will go throught althought in general i think the whole group will be really close together and only 3 or so points will seperate bottom from top.
Group B, CSKA Moscow Inter lille Trabzonspor i think it'll be a fairly easy group for inter, but moscow and lille will fight for second place.
Group C Man united, Benfica, Basle, SC Otelul Galati. This will be a very easy group to predict in my opinion, Man united to finish top and benfica to finish second by confortable margins in my opinion.
Group D Dinamo Zagreb, Lyon, Real madrid, Ajax. i think real madrid will walk it with at least 4 wins and only 1 loss at max, with lyon and ajax to fight for third.
Group E. Bayer leverkusen, Chelsea, Genk, Valencia. this will be a tough group for whoever tries to finish second. i think chelsea will come first ( with some problems ) while leverkusen and valencia will both fight for 2nd but with genk having an outside change, their not to bad of a team.
Group F. Arsenal, Borussia Dortmund, Marseille, Olympiakos. I honestly just think it'll be a very close fight for both 1st and 2nd place, between marseille, dortmund and arsenal.
Group G Porto, Apoel Nicosia, Shakhtar Donetsk, Zenit St Petersburg, all 3 of Shakhtar donestk, zenit st petersburd, and porto are all similar in terms of quality and it'll be a close fight for 1st place, but probably porto to finish top with donestk finish 2nd. the easiest group to play for last 16.
Group H AC Milan, BATE Borisov, Barcelona, Plzen, Barcalona to win 5 if not all 6 of their games and ac milan to come second. i think its that simple for this group.
