Sheffield United: Blades took care of contract business last season

Jack O'Connell, David McGoldrick and captain Billy Sharp were among a raft of players who committed their futures to the club during United's promotion winning campaign.

But allaying fears he could be forced to devote some of his time to ensuring they are rewarded for securing Premier League status, Wilder said: "It's all taken care of. There's thing in them (the contracts) which sort all of that.

"So there's nothing to worry about there. We don't envisage having to sort stuff like that out because, like I say, it's been done already."

John Fleck and Enda Stevens were also handed new and improved agreements as United plotted a course back into the top-flight for the first time since 2007. Like John Egan, who became their record transfer signing when he arrived from Brentford a year ago, they are also thought to have been guaranteed a wage increase if United returned to the highest level.

Wilder stressed the importance of improving housekeeping behind the scenes when he took charge of United in 2016.

Revealing how he once inherited a situation where "half of the bus could walk out for nothing" at one of his previous positings, the former Northampton Town and Oxford chief also spoke about "bringing the power back to the football club" earlier this summer.

"It's something we needed to take a look at," he added recently. "To be successful, to be able to build something sustainable, you've got to be in control and I think we've done that. It benefits everyone to be honest, us and the individuals concerned. What we've got to do now is make sure we keep that going and identify where we can do better."

The efforts of United's footballing administration department means Wilder is free to focus his attention on making the necessary additions to his squad ahead of August's return to action.

"All of that stuff is sorted. You've got to give people incentives and reward them where and when it's possible.

"The same goes for next season as well. We know what we've got to do."
