I agree, it’s even harder to believe if you hold Everton up as a business that knows what it’s doing and has competence across the entire business (not what I’m suggesting you are doing btw). Everything this club does and has done for years is under those 2 bells in charge.
Moshiri gave Benitez full licence to do whatever he wanted I believe. This is something I have been told although I wouldn’t bet my house on it, it makes some sense in to why that particular manager would take a job at the club who he knew would hate him (let’s face it, Moshiri has previous for letting others make decisions for him and his/ usmanov‘s money). Benitez having more control over staffing is probably the biggest reason Bill didn’t want him.
After being burned by letting a manager have all the control we are back to the old ways of the chuckle brothers having to sign everything off.
