If he's shit, it must be absolutely disastrous if the players know this for sure within 1-2 months of the guy's appointment, in a period punctuated by frequent matches, COVID-19, and the holidays. And if he were
that bad that it's
that obvious, then this would have been known before he had joined United. Finally, the tweet doesn't even say his drills are poor, but that they focus on the wrong subject (winning the ball back instead of possession), which I would assume is Rangnick's decision, not Armas's.
So yeah, I would put this on the players at this point. I would also be curious which individuals 'the players' refers to. Are we even talking about the majority of the team or key players here?
Or maybe
@limerickcitykid is right and Armas has zero redeeming features and that was known already; but then why did Rangnick hire him? Something is definitely off here.
