I don't think Bayern have any positive surprises in this encounter and let me remind you that this is just a battle of words between Tuchel and Ancellotti, from the looks of things I think the Madrid boss won.
There's certain thing called levels in the UEFA Champions League this season, we have different managerial obligations pointed by these managers. Real Madrid vs Bayern Munich in the semi-final happens to be one of the tough matches and one wouldn't afford to missed out. I'll ensure I rearrange my scheduled because this is UEFA Champions League night and only the best will grant posited results for their supporters. Thomas Tuchel and Carlo Ancelotti are experienced but when it comes to facing eachother, its entirely different decision to make.
