The whole footballing side needs to change after Wenger leaves. It is no good just saying we need coach x,y or z, because we really need a director of football and more people with footballing backgrounds in the higher positions of the club.
Wenger is the only footballing authority at Arsenal and it is why we have struggled so much. Sir Chips said they just let him do as he wants. The board culture needs to change.
I would love to see Tony Adams on the board as an advisor. He was Mr Arsenal and while he might not be a tactical genius or have a footballing philosophy, he will always have the best interest of the club at heart.
I would love to see Dennis Bergkamp as Director of Football. He has the Dutch total football philosophy running through his blood. Or maybe Viera, someone who knows about both attacking and defending and what it takes to win at the highest level. Both also have good youth backgrounds. Ultimately, this doesn't have to be an ex Arsenal player, but I don't want it to be a suit who has never played the game. I think this will be the top priority once Wenger goes rather than who the next coach will be.
The coach needs to be someone who can work within the parameters outlined by the director of football. Ideally someone who is a good man manager and tactically astute.
