APOEL scoring 3 at the Bernabeu, keeping Real Madrid scoreless for 90 minutes, only to take it to extra time and needing to score once more AND not concede, again AT the Bernabeu, is simply impossible. In saying that, APOEL have been an amazing story this year, but I doubt they'll reach any great heights next season.
I wouldn't rule Benfica out completely as it's only a one goal deficit. If AVB was still in charge (they wouldn't be in the CL still) then you'd definitely consider this an even match. Di Matteo has really turned things around, and you'd think Chelsea would manage to get through. I'd say 2-1 to Chelsea.
Real Madrid vs. Bayern Munich and Barcelona vs. Chelsea sounds fucking awesome.
