Former England international striker Bull told the Mirror: "Coming to Stafford is like turning the clock back 20 years in my career: there is no fitness room, no sauna, no jacuzzi but I love the place because it's brought me back to grass-roots and what I used to do before.
"I'm a man of challenges. I used to break records for a living at Wolves, and this job is right up my street.
"It's not too demanding when you spend every week on your backside, playing golf every other day, going to the races and doing a bit of handshaking at Wolves on a Saturday.
"After eight years on my a**e, I decided it was time to find myself a proper job."
He said: "I made my England debut against Scotland at Hampden Park in 1989 he scored, of course when Wolves were still in the old Third Division. You won't ever see that happening again. Unless you play for Man United, Chelsea, Arsenal or Liverpool, you've got no chance of playing for England these days, which is wrong.
"I could have joined Torino after the 1990 World Cup, but after six weeks of going up and down Italy I decided I would miss my English breakfasts. And I could have gone to Newcastle when they signed Andy Cole, but I just couldn't leave Wolves."
