Chris Wilder says Tuesday's Carabao Cup tie against Leicester City will give several members of the squad the chance to impress.
Speaking ahead of the clash against the Foxes, Wilder revealed he will rotate his pack again, but insists he expects his team to give the 2016 Premier League winners a run for their money.
Looking ahead he remarked: "We're going to change it round again. We did it against Walsall and will do again on Tuesday night.
"It's not just about looking at the next game, we have to look ahead and plan.
"But it's a good opportunity for George Baldock to make his debut, he's an exciting player who picked up an unfortunate injury in pre-season.
"Ched and Caolan will play and John Lundstram is another who will get an opportunity, along with Carruthers and David Brooks."
Wilder added: "Whatever team puts that shirt on we want them to make a difference, impress and grab the opportunity with both hands.
"We didn't do that against Walsall, but hopefully they do against Leicester, who will make changes with Manchester United at Old Trafford awaiting them at the weekend."
