Ange Postecoglou's reign as a Premier League head coach at Nottingham Forest is the second-shortest in the competition’s 33-year history.
Forest parted company with Postecoglou on Saturday after a 3-0 home defeat to Chelsea left them in 17th, one point above the relegation zone, ahead of the 15:00 BST matches.
It was their sixth defeat in eight matches since the former Tottenham Hotspur head coach took over from Nuno Espirito Santo.
Postecoglou's sacking came just 39 days after he joined Forest.
Allardyce the shortest reign
Sam Allardyce holds the unwanted record of the shortest reign as manager at a Premier League club on his own, spending 30 days at Leeds United in May and June 2023.
Allardyce was in charge for four games - which ended in relegation - losing three and drawing one of those matches and he left when his contract ran out on 2 June 2023.

Postecoglou's record of four defeats in five Premier League matches also makes him statistically one of the least successful managers in the competition.
His 0.2 points-per-match average is the joint fourth-lowest, the same as Allardyce, but still better than the zero points claimed by Frank de Boer during his four matches in charge at Crystal Palace in August and September 2017.

In comparison, Forest's previous head coach Nuno averaged 1.42 points per match at the City Ground.
Postecoglou is also the first manager to see his team score only one goal in his first five Premier League matches in charge since Sean Dyche at Burnley in 2014.
With Forest sitting in 17th, and with the joint-worst goal difference in the division ahead of the 15:00 BST matches, the club will hope their next manager can address the slide for a team who finished seventh last season.
