A good few do, Norwich, Sunderland, Watford, Southampton, Leicester etc. I know Stoke don't have one they've got a similar set up to us with Peter Coates and his son running everything and they've had the same problems as us, wasted so much money on average players and heavily reliant on the individual managers transfers and philosophy. It cant be a coincidence they've not been able to bounce back to the prem not even manage a top 6 push since relegation in 2018. The director of football is the modern way now, in how clubs keep to a philosophy and appoint managers and players to suit it.
