Crikey, have you watched or heard the comments from SS?
The whole video explained everything.
The identification of what is wanted- granular detail down to certain areas of the pitch.
The scouting process that follows, not just videos, data etc but chatting to poeple about their character.
There are no assumptions whatsoever- the process was fully explained.
They simply wouldn't be here if they didn't meet those requirements.
That's what forms the basis of player acquisition and for me, confidence in the whole as much as an individual. Synergistic approach.
Unless we're buying players for big money, with completely proven backgrounds, then there is never loads of evidence of their suitability, and even then, no guarantees.
It's simply a case of trusting the manager to do his job, and he has proven before that he can do it at this level, using this approach.
You won't hear him trumpeting himself and his team as the best in the league, but he is clear about his methods and requirements, and seemingly confident in himself, albeit with the humility to acknowledge his own failings and nervousness.
