Nigel Clough was most recently manager of Burton Albion, having rejoined the club for a second spell on 7th December 2015.
The former Nottingham Forest, Liverpool and England forward retraced his famous father's footsteps when he took charge of Derby on January 6th, 2009.
It was under Brian Clough's tutillage that Nigel began his league career at Nottingham Forest in 1984. He made 403 appearances in two spells with the club, becoming the second highest scorer in Forest's history with 131 goals.
His intelligent probing as a deep-lying centre forward - the same position his dad had played, albeit with a difference in style - saw Nigel collect 14 England caps.
Forest won the League Cup twice in successive years - 1989 and '90 - during his initial nine years at the City Ground. Nigel scored twice against Luton at Wembley in the first of those triumphs.
After three years with Liverpool, he wound up at Manchester City - from where he returned to Forest on loan - but continued to play after being appointed manager of non-league Burton in 1998.
Clough's team made steady progress and, in his fourth season, were champions of the Northern Premier League to win promotion to the Conference. They were firmly on course to climb into the Football League when he was lured to Pride Park. At the end of the 2008/09 season Burton did achieve promotion, which resulted in the side entering the Football League for the first time in their history.
Before Nigel's departure his table-topping side recorded a run of 11 straight victories. He had declined many overtures from league clubs but could not resist the pull of Derby where Brian won promotion and the league championship early in his inspirational career.
County had relegation fears when Nigel took charge but their form improved - and he also presided over a memorable FA Cup replay victory over Midlands rivals Forest as the side recovered from a two-goal deficit to win 3-2.
In his first full season in charge, Clough guided Derby to 14th in the Championship, four places better off than the previous campaign. He once again established their Championship status during the 2010/11 season.
In 2011/12, Clough guided the club to their best start to a season in 106 years as they opened with four victories from four. After another positive campaign, he progressed with the club into his fifth successive campaign in the Championship. Later in 2012/13, Derby recorded a 10th place finish in the Championship.
At the time of his departure in September 2013, Clough was the fourth longest-serving manager in English football and the longest serving in the Championship.
Following Clough's appointment at Bramall Lane the club's position rapidly transformed as having taken charge when the Blades were in the relegation zone, he eventually guided them to a 7th place finish in Sky Bet League One.
His team also became the first third-tier side to reach the last four of The FA Cup since Wycombe Wanderers in 2001. Their run which coincided with a 10 game winning streak included victories over Premier League sides - Aston Villa and Fulham - plus Championship sides Nottingham Forest and Charlton Athletic on their way to Wembley. This success resulted in Clough being named the Budweiser FA Cup Manager of the Year at the League Managers Association 22nd Annual Awards Dinner 2014.
Clough's return to the Pirelli Stadium saw him guide the club to the Championship for the first time in their history.
