I think Aston Villa and Dortmund have no chance of qualifying for the next round... About Inter vs Bayern and Madrid vs Arsenal it's really hard to guess the winners... Although Madrid have a lot of experience of playing against English teams in the UCL, I think they will have a better chance of winning... Although I don't rule out surprises in these matches...
There is high chances they might not qualify, dortmund is always trying in the champions league because his always trying because even last season they got to the finals but they were unable to beat Madrid who are the king of champions league and there is a lot for the other clubs to learn. and there are a lot of tough matches ahead and fans are really anticipating all the games.
And we can see that arsenal is going smoothly but there journey is coming to an end already in the champions league because how on earth will they be able to defeat real Madrid and if that should eventually happen then, Madrid is playing in there own experience and with how arsenal have not been in shape it is going to be a hard one for them to play and bayern vs inter is another game that will come with enough entertainment.
