The game was pretty even in terms of chances, but Bayern had more territory and possession.
When you consider that Man Utd were full strength, while Bayern were missing three key players, I don't see how you can think the second game will be easy for Man Utd.
Man Utd were pretty average really, the sad thing is that too often in Europe that has been enough as they have only had to turn up for one leg. Hopefully Bayern score first in the second leg as that would scare the life out of them, and Bayern could hit them with pace on the break. Either that or a really drawn out 0-0 where Utd have to push forward more and more.
