"England based managers that he knew" = Southgate & Potter = I agree with SJR, they suck
That said, I was on the "What's so much better about Dan Ashworth over other names that we don't have to fight with Newcastle over?" at the time. I would have been just as happy with Paul Mitchell (who was available at the time). Not sure why they thought Dan Ashworth was was so great that it was worth paying Newcastle a buyout and waiting 6 months for him.
Whatever the problem was, though… I would admit he seemed to perform much better than Murtough. Admittedly a low bar.
