Well, that's just making the situation look too easy. In the first match, there were different parts of the match: BVB attacking for some minutes, Real in defence, then Real attacking for some minutes, BVB in defence, similiar to the first half today. The problem was that Real was just too good in the second half. We had the chances to attack after like 60 or 65 minutes but were just happy enough to lower the speed of the game and relax a bit when we got the ball.
And after the goal, well, it's easy to give everything in the last 3 minutes. Great from Leitner there to come in in such a match and win a ball against CR7 and keep possession very well. It doesn't make sense to give everything for 70 minutes and then colapse and concede 3 or 4 goals, though.
