Clough has been in charge at the Rams since January 2009 and the club would like to place on record their thanks to him for his tireless efforts to bring stability to Derby County, and his hard work and dedication throughout his tenure.
However, after much consideration, the board feel it is time to move Derby County forward to the next level, which will necessitate a comprehensive review of the club’s football operations.
Here's what Clough had to say after the 1-0 loss to Forest, and before he knew his fate to come.
"I am very pleased with the performance, I thought we were very good," he said, as per Sky Sports. "Once we got the first five or 10 minutes out of the way where they came at us, I thought we settled down and played some very good football.
"We are pleased with a lot of things we did, just not the result."
The board at Derby County were clearly less convinced.
Clough arrived at Derby during turbulent times for the club in January 2009 and, as per this BBC report, has been managing on a reduced budget this season as the club try to get their financial affairs in order.
Derby's loss at Forest was their third in a row, but the reaction on Twitter to Clough's sacking has been largely one of bemusement:
The 47-year-old Clough spent the best years of his playing career at Forest. They were also the club his legendary late father Brian took to European glory, but this chapter of Clough junior's career will not remember the City Ground so fondly.
Nigel Clough stepped into management with non-league Burton Albion, which he ultimately elevated to the full professional ranks. An offer to follow in his dad's footsteps at Derby followed, and Clough accepted. Hopes were high that this season might see Clough junior achieve the promotion feat his father did with the Rams.
Here's what Clough had to say before the current campaign kicked off, as per an interview with the Daily Telegraph.
"We might be here for two more weeks or two months, you just don’t know. The sack isn’t something we’re worried about because it will happen, if they don’t carry us out in a box first."
As per this BBC report, Clough was the fourth longest-serving manager in England, "behind Arsene Wenger, Paul Tisdale and Chris Wilder, and the longest in the Championship."
