You're not wrong in saying we made sloppy mistakes for their goals. The problem is, with the way we play we put ourselves under pressure constantly, we almost encourage it in order for us to get through them and so you cannot expect zero mistakes over 90 minutes.
we pass side to side and give crazy passes to players under intense pressure for very little if any benefit for most of the game and we do it knowing if we lose the ball, which we inevitably will at some point, then we suddenly have a massive problem. It's a needless high risk for no reward.
