It is made up nonsense.
If Will Still is being told to only to play a particular system, why isn't he being told to not speak in press conferences about playing a different system? Why does the SR all-controlling bogeyman controlling one element but not the other?
There's loads of things Still says in press conferences like the team working hard, being quick in transition, converting chances, scoring goals, winning etc etc etc but they're not doing that either.
Maybe Still says stuff in press conferences that he can't actually achieve because he isn’t up to it? Maybe, just maybe, it's that.
