Nottingham Forest sacked Ange Postecoglou just 39 days after hiring him — but are they one of the most impatient clubs in Premier League history when it comes to how they treat their managers?
Surprisingly, the data suggests they are not. FootballBlog.co.uk has calculated the average length of time a manager has kept their job at each club in the Premier League era and, based on our findings, only three of the 20 current top-flight teams have been more patient than Forest.
However, that is in no small part due to the fact that their first Premier League manager, Brian Clough, was in the job for 6,697 days.
Forest’s average will likely fall over the coming years — especially if Evangelos Marinakis remains as owner at the City Ground!
Average tenure for a Nottingham Forest manager during the Premier League era: 1,462 days
- Brian Clough: 6,697 days
- Frank Clark: 1,317 days
- Steve Cooper: 819 days
- Nuno Espirito Santo: 629 days
- Dave Bassett: 607 days
- Ron Atkinson: 125 days
- Ange Postecoglou: 39 days
What is the average length of a Premier League manager’s reign?
The mean average length of a Premier League manager’s reign is 891 days, which is just under two and a half years.
That figure is based on all managers who were not caretaker or interim appointments and whose continuous spell included at least one Premier League match. It also excludes spells that are currently ongoing.
The median length of time that a Premier League manager stays in a job is 607 days, while the mode is 629 days — which matches the length of spells served by Nuno Espirito Santo, Nigel Adkins and Ron Atkinson at Nottingham Forest, Reading and Coventry City respectively.
Only six clubs have competed in every season of the Premier League to date. They are Manchester United, Arsenal, Chelsea, Liverpool, Tottenham Hotspur and Everton. The mean spell of a Premier League manager at one of those ever-present clubs has been 1,078 days.
Which Premier League club is the most patient with managers?
If we calculate patience purely on the average time a manager has stayed in his job at each club, then Arsenal are by far the most patient of the 20 clubs currently in the Premier League.
Not including current boss Mikel Arteta, the Gunners have had four permanent managers during the Premier League era: George Graham (3,205 days), Bruce Rioch (431 days), Arsene Wenger (7,894 days) and Unai Emery (555 days).
The average spell of Arsenal’s first four Premier League managers was 3,021 days, while Wenger remains second on the list of longest-serving Premier League managers — behind only Manchester United legend Sir Alex Ferguson.
There is technically one club from the Premier League era whose average is longer than Arsenal’s. That is Oldham Athletic, whose one and only manager during their sole Premier League season in 1992/93 was Joe Royle.
Royle spent 4,502 days in charge of Oldham from 1982 to 1994. Like Brian Clough at Forest, he still qualifies under the rules of this study even though the vast majority of his time in the role was spent outside the Premier League.
Average tenure for an Arsenal manager during the Premier League era: 3,021 days
- George Graham: 3,205 days
- Bruce Rioch: 431 days
- Arsene Wenger: 7,894 days
- Unai Emery: 555 days
Which Premier League club is the least patient with managers?
Perhaps unsurprisingly, Chelsea have been the least patient Premier League club with their managers.
Chelsea’s 18 permanent Premier League bosses — excluding current manager Enzo Maresca — have averaged 623 days in charge.
Claudio Ranieri lasted the longest of any Chelsea manager in the Premier League at 1,351 days, while Graham Potter’s 206-day spell sits at the other end of the scale.
Average tenure for a Chelsea manager during the Premier League era: 623 days

- Jose Mourinho: 1,205 days
- Glenn Hoddle: 1,071 days
- Gianluca Vialli: 943 days
- Jose Mourinho: 927 days
- Antonio Conte: 740 days
- Carlo Ancelotti: 720 days
- Ruud Gullit: 643 days
- Ian Porterfield: 615 days
- Thomas Tuchel: 588 days
- Frank Lampard: 571 days
- Maurizio Sarri: 337 days
- Mauricio Pochettino: 325 days
- Roberto Di Matteo: 262 days
- Andre Villas-Boas: 256 days
- Avram Grant: 238 days
- Luiz Felipe Scolari: 223 days
- Graham Potter: 206 days
As revealed by FootballBlog.co.uk recently, Chelsea have spent £156.6 million on compensation after sacking managers during the Premier League era.
That total is roughly the same as Manchester United (£52.4m), Liverpool (£50.8m), Arsenal (£29.3m) and Manchester City (£24.25m) combined.

Does Ange Postecoglou hold the record for shortest managerial tenure in Premier League history?
No. Ange Postecoglou’s sacking after just 39 days places him second on the list of shortest-serving managers in Premier League history.
Not including managers who were specifically appointed as caretakers or interim bosses, the only Premier League manager to have a shorter tenure than Postecoglou was Sam Allardyce, who spent just 30 days in charge of Leeds United in 2023.
Allardyce was brought in on an initial short-term contract on May 3, with the aim of keeping Leeds in the Premier League. But he failed to win any of his four games in charge, Leeds were relegated, and it was decided on June 2 that he would not continue in the role.

1. Sam Allardyce — 30 days as Leeds United manager (2023)

Methodology
This study analysed every permanent manager to have taken charge of a Premier League club since the competition began in 1992.
Managers who oversaw at least one Premier League match were included, but caretaker and interim managers were excluded, as were managers currently in their jobs, to prevent ongoing tenures from skewing the averages.
For consistency, each manager’s full continuous spell in charge was counted — including days before or after any relegation or promotion.
For managers who were in post before the Premier League began and continued into the Premier League era, we have included the full length of their tenure, including the period before 1992.
All figures were calculated using available start and end dates, measured in calendar days.
