"Chris has put himself forward to be interviewed for the role," he told BBC Radio Sheffield.
"We had around 20 applicants of quality for the position and narrowed the shortlist down to about seven.
"We did quite a lot of work in preparing a managerial profile. We want a manager who wants to develop and improve players.
"Chris stepped into the breach at a difficult moment and everyone has been open with him that other candidates will be interviewed.
"The manager is pivotal to the challenges we face. It is about creating an identity on and off the pitch, a philosophy and a new culture. The club has to change because it can't continue with the model it has had."
