Barnsley have signed Arsenal playmaker Dan Crowley on a half-season loan.
MK Dons have signed midfielder Sergio Aguza from Real Madrid Castilla.
Danny Wilson has warned that memories count for nothing after returning for a second spell as Barnsley manager.
Wilson, who famously led the Reds into the Premier League for the one and only time in the club's history in 1997, is back at Oakwell after being appointed as David Flitcroft's successor on Tuesday afternoon.
He remains an iconic figure at the club following that achievement almost 20 years ago, in what was his first job in management, but his brief is very different this time around as Barnsley are rooted to the bottom of the Sky Bet Championship and three points adrift of safety.
Although he returns to the club with a huge amount of good memories, Wilson insists he is starting with a clean slate.
"It's a little surreal but it's very exciting to be back and I am really looking forward to it," said Wilson, who has been out of work since leaving Sheffield United in April.
"You don't often envisage coming back to an old club where you have had so much success but fortunately from my point of view it has happened.
"The situation is completely different now, for all the memories that we have from many years ago, that really counts for nothing now.
"But it's a feel-good factor from my point of view but it certainly won't get us a result on Saturday.
"But I think the whole scenario is fantastic, to come back is a bit of a dream."
Wilson takes the reins from caretaker Micky Mellon, who was placed in charge following Flitcroft's sacking last month, though Mellon will stay on as Wilson's assistant.
The former Fleetwood boss was given the chance to make the role his own and did a reasonable job, taking four points from three games, but the Barnsley board decided that Wilson was their man.
Chief executive Ben Mansford said: "The board felt that the club needed a manager to take us onwards and upwards and after careful consideration Danny was the unquestionable person to take us forward.
"When we looked at the shortlist of applicants and candidates there was one person at the top that could drive this football club forward, unite the football club and have the experience to manage a situation.
"Once we outlined the situation to Danny I don't think we had anywhere else to go and he was offered the opportunity and he grasped it."
Wilson, who has managed at Sheffield Wednesday, Bristol City, Hartlepool, MK Dons, Swindon and Sheffield United since leaving Oakwell in 1998, knows how tough it will be to keep the Reds up this season.
"It's a challenge and it's going to be a tough one, make no bones about it," he added.
"We have got some very tough games coming up but what I have seen from the players already is that they have got the quality to stay up and we have to fire the belief into the players that they can do it.
"Overall, there is not a great deal wrong, but we're still not getting results so we have to change that around.
"Being at the bottom and nobody expecting anything from us, maybe that is the best place to start from. If we can get a few results people will start looking over their shoulders very quickly."
