Not totally convinced by the “DOF model”, but get the idea behind it... Except I don’t think the DOF should be telling a coach what formation he should be playing, surely that’s down to the coach approaching each game on its own merit? Otherwise the DOF is effectively the manager and the head coach is simply one of his coaching staff?!
Anyway, sounds like it would suddenly make the head coach role more accessible to someone like Arteta (especially if he’s already that highly regarded as just that - a coach...).
Not necessarily for/against any of this... just nice that there is hope again that next season might be more than just a bit of hoofball...
