"When Mick McCarthy departed, it was more the timing that shocked everybody. That's why the latter part of the season was really tough for us all.
"But there's no better way of freshening things up than bringing in somebody from a different culture and a different background. He'll want his own style, to do things in his own way."
Wolves will compete in the second tier of English football alongside former Premier League outfits Blackburn Rovers and Bolton Wanderers.
