Let's look at the whole year then. 12 games played. 4 wins (Israel, Oman, CR) 2 losses, 6 draws. 2 (!) clean sheets against Israel and CR. That's not good enough, especially since 2018 happened. Flick and his gung-ho style has worked at times at Bayern, only his first season, and at his NT start but it doesn't yield the results it should and if you know about the inefficiency of your attacking players (hardly a real striker was played) and the dubious quality of your defenders the manager should be looked at very closely.
