I'm sure a couple of drama would still unfold here.
I've seen many games where the game was fiery but then after one of the teams was sent off they closed down and there were no more goals scored, I hope this is exactly the kind of game
I think Simeone/Mourinho would have easily hold the score in such a situation. Let's see what tactics Arteta chooses, he was lucky that it happened right before the break and he can completely rebuild the game in normal mode, and not try to shout his ideas from the edge of the field.
P.S. My easiest bet on Haaland paid off
