While both Carr and Charnley are part of the problem, and in an ideal world would be replaced, any replacements under Ashley's ownership would likely only get the job on the provision they follow Ashley's instructions. Unless there is a change in philosophy from Ashley I can't see much changing regardless of staff (in the Carr/Charnley roles).
Can only hope that Rafa is able to convince Ashley that there HAS to be a change in the way he does things.
