How it was received by the players and coaches has no bearing on how it was conceived and thought of by Arteta. It's quite clear from this kind of shit and the stuff that was in the documentary that he sees himself as some type of psychological savant, which is quite amusing.
I don't understand why people get tribal about this shit - if a Utd manager was pulling this kind of stuff, or coming out with the shit that Rodgers used to serve, I'd laugh about it and wouldn't dream of trying to find justifications to it. It's genuinely ridiculous. It doesn't matter so much as at the end of the day he's good at what he does as a coach, but these stunts come across as some bullshit middle-management initiatives that would end up as a self-serving LinkedIn post the next day. It's ok to say so.
