100% agree. That's why Im not too fussed about Silva's appointment. Brands will set out the style, formations and footballing philosophies whilst the 1st team, U23 and youth team coaches will be required to coach their players in accordance with the Brands doctrine.
Each coach will be constantly monitored and assessed to ensure that they are doing what is expected of them - no freelancing!
I think there are doubts with a lot of supporters in relation to Silva's defensive coaching (or lack of it) but that will be addressed by Brands as the almighty Dutch overlord of Finch Farm. Maybe that's why Emery, Fonseca et al were never really in the frame as they would never fit into this model.
From what I know, Emery and Fonseca would fit that model.
I mean Emery had Monci at Sevilla and I doubt the French let him sign players.
