Being Devils ad for a second, a lot of Bayern's positive approach was dictated by the situation tbf. Real were far more scared of conceding because they had far more to lose. At 2-1, however many they score Bayern's task remains the same, pegging one back, Whereas if Bayern score Real need 2. Hence why they came out of the traps so quick looking for a large lead and then got cautious when Bayern scored. We've behaved the same many times tbh. Fergies often been a fan of that tactic.
Personally I think away goals should stop counting in ET...but then of course one team would still have home advantage. Tough one.
