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.
Well most times the Champions league is always full of surprises if we check am last season Dortmund put up a great fright that last season well from my perspective i think Madrid have more experience and great qualities in the Champions league which they usually take over it with the matter of time, just as we all have seen Arsenal are have a good run but facing Madrid will be more defensive
an will be a different ball game which between themselves but if Arsenal manage to pull this off it would be more shocking but on a second thought Madrid are really thriving for more in this situation,
Bayern's vs Inter is going to be an interesting game so far well all know how the the both teams are too good so this could be something the both teams will be thriving for, and from this stage of the competition is where thing really get intense the both heart meant will be biting fast in as much both teams don't want to agree for the wins.
