I suspect (as if it wasn't obvious) Marinakis is the problem, he's either hot headed, impatient, very nervous of relegation, doesn't take kindly to failure, so used to getting what he wants...or all of them.
It'll end in disaster if he's not a bit more circumspect.
I didnt particually like Dyches appointment, said so at the time, then softened as he got early results, but somethings gone very wrong, players just aren't performing as they were.
Marinakis will be desperate for that new manager bounce... perhaps that's all he is gambling on. Heck of a gamble
