I think football clubs are big enought to have a technical director and director of football, personally. So if you look at the likes of Edwards at Liverpool, from an analyis background. Would make a ton of sense to me to have a tech director responsible for analysis, medicine, scouting etc. Then look at Edu at Arsenal, a different upbringing again. I suspect he is a trusted advisor on the football side. Poyet could do similar for me, 1st team, u21s, academy oversight from a mgt and coaching perspective. Clearly the glue is still the head coach, but to me an experienced football coach is needed as a sounding board for the all coaching teams in the club.
