Seeing how interesting today's match is, there is a good hope for tomorrow's match especially when the giants who will compete are the big clubs of the EPL, La Liga, Bundesliga and Serie A elbowing each other for 2 other slots to the semi-finals.

Today's match indicates that anyone can still fight for a place in the semi-finals even if they are already behind on aggregate because it does not rule out the possibility of a comeback always happening even though in today's match both Dortmund and Aston Villa failed to do so but with the number of goals produced in the second leg this time there is certainly a hope for Madrid in tomorrow's match to do the same.
Inter and Bayern are still quite dominant and their aggregates are quite small so it could be a bit of a toss-up between Arsenal and Madrid. Because after all, although surprises can happen, for the Arsenal and Madrid match tomorrow, Arsenal are definitely the favorites to qualify even though they play at the Bernabeu.
