Portsmouth have named Richie Barker as their new manager and Steve Coppell as director of football.
Wigan have announced Uwe Rosler as their new manager after agreeing compensation with Brentford.
Harry Redknapp has confirmed his appointment as QPR's new manager is imminent.
He told Sky Sports News: "Hopefully we can get it done tonight, there shouldn't be any problems."
Redknapp continued: "There are a couple of bits to be sorted out tonight but I've left it to other people and said I want it to happen because it's a club I want to manage.
"I'm looking forward to it. It's a big challenge and a tough job to take on - but I'm up for the challenge."
The 65-year-old confirmed he was hoping to travel up to Saturday's Barclays Premier League match at Manchester United, before making Tuesday's match at Sunderland his first in charge.
Redknapp said: "I'll watch the game tomorrow. I will probably travel up and watch the game in the stand.
"If everything gets sorted, and I'm sure it will, I'll be in Sunday morning, will have the team in training on Monday, then fly up to Sunderland."
QPR are bottom of the table with only four points from 12 games and Mark Hughes paid for the west London club's poor start with the sack on Friday morning.
Redknapp said: "You know what the game's like. I lost my job at Tottenham and Mark Hughes is a top, top manager and a great guy. Sometimes these things happen.
"QPR couldn't get the results they needed. You couldn't have too many worse starts but I'm ready to give it a go and see if I can change their fortunes around. If I can keep them up I'll be the happiest man around.
"There are some good players there but I've got to find a way of picking a team that can win some games.
Redknapp thinks the current group players will be the ones to get the Loftus Road club out of their current predicament.
He said: "I dont think too much will happen in January. There is a big staff there and you can't keep bringing players in. The players have got to start performing.
"If they do that we've got a chance...find a way to pick up points, be hard to beat and win some matches. It's all about the players."
The former Bournemouth, West Ham, Portsmouth and Southampton manager also revealed he hopes regular cohorts Joe Jordan and Kevin Bond will continue to be a part of his background team.
He said: "They obviously want to get back into work as well - but Mark Bowen and Eddie Niedzwiecki are there (QPR) at the moment and they are great lads as well. Let's hope they can get a result tomorrow at Old Trafford."
He admitted the vacant manager's position with the Ukraine national team also appealed, adding: "Yesterday I was almost on my way to the Ukraine. It was something I fancied doing - but this has changed everything around."
Hughes paid with his job after leading the team to just eight wins in all competitions under his leadership.
QPR owner Tony Fernandes consistently came out on Twitter to back Hughes but the 3-1 home defeat to fellow strugglers Southampton last weekend appears to have been the final straw for the board.
A statement from the club read: "The board of directors wish to thank Mark for his commitment, hard work and dedication in his 10 months in charge.
"Mark has shown integrity and professionalism throughout his time here, but ultimately the circumstances we find ourselves in have left the board of directors with very little choice but to make a change."
Redknapp took charge of Spurs when the club were bottom of the table and ended up guiding the north London side to two fourth-place finishes during his spell at White Hart Lane.
