There's still the the problem with his views about defense. That's the big elephant in the room with Flick. This is probably what got Bayern fans fed up with him despite the attacking football he played there.
He's not viewed that great by Bayern fans.
That's not the impression I got from the Bayern fans I have spoken to.
They have however said he has some flaws which is showing right now. Basically not willing to adapt to the players he has.
Flick's style simply requires some seriously athletic players, especially in defence, and some depth. Our only players fitting that bill is Araujo who is retarded and a liability on the ball and Balde who looks clueless 80% of the time.
I suppose the other approach would be to get a more pragmatic, conservative manager that can make these milquetoasts work, but then the fans will complain about the boring football being played.
