Chris Wilder has named five Sheffield United players who can leave the club this month.
The Blades boss is looking to let some players loose in order to replenish his squad.
"There are boys going out," Wilder confirmed.
"Richard Stearman [is likely to be one]. Kean Bryan needs games, Leon Clarke, Jake Wright and Ben Heneghan [are all available].
"If we receive bids from anybody, we'll always assess them and do what's right for the football club.
"And we have positions we need to strengthen. We're not [going to be] bringing in four, five or six players.
"The group is good at the moment, they are in a good place. It's an important window and it's just a tinker and hopefully we can do that in January."
