Former Sheffield United star Neill Collins believes the club has to make big changes to their squad.
Given they are almost certain to get relegated, Collins believes that a refresh is needed.
He does not feel that retaining the same core group would be enough to come straight back up from the Championship.
"There are two ways to get promoted out of the Championship," Collins, who is in charge at Barnsley, told the Yorkshire Post.
"You have to have a hunger, maybe a team that's not experienced it before, which could mean wholesale changes.
“The other way, as the likes of Leicester have done, is to keep hold of a lot of your quality and ultimately you're just too strong for that division.
"I suspect Sheffield United might need to be the first. Watching them from the side they look like they need to rejuvenate that squad and go again because I think they've probably suffered from the fact their players have climbed the mountain, gone down and climbed it again. Now it's just a little too much for them, and they need fresh blood."
