I had no expectation whatsoever for the draw, as every team would look at us as the minnows from the poorlands, and Porto would have low odds against any other team, so picking one would be pointless.
For all that matters, anything can happen. We've beaten Utd before twice, were only knocked out by Chelsea a couple of years ago after a gigantic blunder from Helton, Liverpool in 2006 were knocked out clean by Benfica, and while not saying Porto will win it, if Utd keeps dropping points in the prem and isn't allowed to go easy on weekend matches, we might have a chance.
And Atlético also thought they got the "good" draw, and even the spanish press agrees both results were too flattering to them.
My main concern are the wingbacks - not if they're that good at all to begin with (which they aren't), but if they'll even be fit enough to play.
