It's 2017, though, and we should be beyond knowing that those calls would have gone differently in a neutral country or in Germany. I hate that aspect of it. These are supposed to be the best referees in the world.
It was certainly an odd tie, though - Real Madrid outplayed Bayern for most of the match in Munich, and the reverse happened for the first 90 in Madrid (despite no goals for Bayern in open play).
I do expect RM to win this weekend. They have been the better side between the two for months now.
