Sheffield United captain Billy Sharp is confident Manchester United goalkeeper Dean Henderson will return to Bramall Lane.
Henderson, a member of the United squad which secured promotion from the Championship last term, is expected to sign a new contract with Ole Gunnar Solskjær's side before being allowed to rejoin Wilder's team.
"Dean is a great 'keeper, he knows the club and he's made it clear he wants to come back," Sharp said.
"I'm sure it will get done soon and, if not, we'll sign someone else."
He also told the Sheffield Star: "We know it's going to be tough and hopefully we'll sign a few to make us stronger.
"But we're not a group that fears anything and we've not lost a game for a while. When we lose, we normally bounce back with a positive result. That's a quality we'll be looking to keep and I'm sure we can."
