And at this stage Real Madrid has gotten to I don't think it will be easy for any team or club to knock them out because there experience here is mad whether inform or not and even if it was Barcelona they are playing with in this stage I doubt if Barcelona will defeat them despite the form because champions league is Real Madrid thing I mean is like what they do for a living and Arsenal is too small to challenge them though they can try.
There is no doubt that Madrid has more experience in the UCL, they already have 15 and are going for 16, so that remains intact, there are still very strong matches left, we must not be confident, Barcelona has to defeat a very tough GERMAN team, Madrid on the other hand has to defeat an Arsenal that always does very well in the UCL, I think that to tell the truth this team is motivated, Madrid must take care of themselves and not give them a unpleasant surprise , they have to go out and look for the match at all times, regardless of fatigue.
I haven't seen Arsenal doing pretty good in UCL, and this is the highest stage that they have reached so far. Madrid is the team that I know has been extraordinary when it come to the Champions League. I believe that there's nothing Arsenal can do to stop their termination from the competition by Madrid. Barcelona need to put in their best performance, because Dortmund shouldn't be underestimated
