Former Nottingham Forest midfielder Martin O'Neill has returned to the City Ground to manage the club.
The 66-year-old, who won the First Division title and two European Cups with the Reds, replaces Aitor Karanka in the job after the Spaniard's departure last week and becomes the 11th full-time boss since 2011.
Here, we take a look at the managerial revolving door at Forest during that time.
Billy Davies: Jan 2009 - June 2011
Succeeded Colin Calderwood and got Forest to the Championship play-offs in each of his two seasons in charge. However, he was unable to repeat what he did at rivals Derby and get the Reds promoted to the Premier League.
Steve McClaren: June 2011 - October 2011
The former England boss lasted just 112 days in charge, resigning amid reports that he was unable to sign two players on loan. Forest won just eight points in McClaren's first 10 league games.
Steve Cotterill: October 2011 - July 2012
Forest agreed a compensation package with Portsmouth to prise Cotterill away from Fratton Park. He kept the Reds in the Championship, finishing 10 points clear of relegation trouble, but left during the close season after the Al-Hasawi family bought the club.
Sean O'Driscoll: July 2012 - December 2012
O'Driscoll was brought to the club by Cotterill to work as first-team coach but left to become manager of Crawley in May 2012. He returned to the City Ground to take the top job without ever taking charge of a competitive match at Crawley. He was sacked after a 4-2 win against Leeds with Forest just one point shy of the Championship play-off places.
Alex McLeish: December 2012 - February 2013
The Scot took over just a day after O'Driscoll departed, but he was gone 40 days later. McLeish cited "a difference of understanding of the development strategy" at the club as the reason for his exit. Forest had pulled out of a deal to sign George Boyd from Peterborough just days earlier.
Billy Davies: February 2013 - March 2014
The Al-Hasawi family turned again to Davies, but his second spell proved to be a controversial and damaging one as he fell out with club staff and banned journalists. He was sacked after a 5-0 defeat to Derby.
Stuart Pearce: July 2014 - February 2015
It began brilliantly for the Forest icon as he steered the Reds to the top of the Championship table early on in the season, However, it soon soured and a run of just three wins in 21 league games, plus an FA Cup defeat to Rochdale, saw the club's former left-back sacked.
Dougie Freedman: February 2015 - March 2016
The Scot survived a run of only three wins in 22 games, spanning two seasons, and turned around the club's fortunes with a 13-game unbeaten run, despite having to work under a transfer embargo. Another sticky patch of one victory in six matches brought his demise.
Philippe Montanier: June 2016 - January 2017
The Frenchman initially oversaw some positive results, but, amid a confusing ownership situation at the City Ground, with the Al-Hasawi family in talks with an American consortium, Forest slipped into relegation trouble after an eight-match winless run.
Mark Warburton: March 2017 - December 2017
The former Brentford and Rangers boss managed to keep Forest in the Championship, but only on goal difference, after taking over from Montanier. An alarming run of form during the 2017/18 campaign saw him sacked on New Year's Eve after a home defeat to Sunderland.
Aitor Karanka: January 2018 - January 2019
The Spaniard was financially backed in the summer ahead of his first full season in charge, including the club record signing of Joao Carvalho for a reported fee of £13.2million. Forest had won one of their last six games when Karanka left, with the club just four points shy of the play-off places. A club statement said Karanka had "asked to be released from his contract."
