If we are aiming at being an established PL side, I would say that starts here. no short term plans but a genuine long term plan for growing football success and revenue.
We need a manager who is capable of managing and delivering a mid table PL side. we then need to plan in a couple of waves for a squad who are capable of going up and staying up.
I am not saying we should get him, but when you look at the work Southgate did from U21 and then taking over as England Manager. It didn't result in silverware, but I don't think anyone would argue that he didn't improve England football performance as a whole. Look at our Under21 side now and the amount of talent now being produced through to the England squad.
That takes time and money but that's what I could get behind.
I don't see any of these names listed as being improvements on Wilder, just a different look to the football.
