Professional football is a ruthless business and management is perhaps the most volatile part of it.
For all the talk of philosophies and long-term plans, managers are rarely in any job long enough to deliver what they promise.
Implementing an ambitious new style of play, promoting youngsters from the academy and building for the future are all noble aims, but results matter more than anything else.
A bad run can see even the most established and highly rated managers come under scrutiny, let alone those with a less impressive track record.
PREMIER LEAGUE Everything you need to know for the 2021/22 season
Patience, from both owners and supporters, can quickly wear thin and, unfairly or not, managers soon outstay their welcome.
Last season was unusually quiet in that season, with just four managers losing their jobs – West Bromwich Albion’s Slaven Bilic, Chelsea’s Frank Lampard, Sheffield United’s Chris Wilder and Tottenham Hotspur’s Jose Mourinho.
The year before there were seven sackings and a struggling Watford were responsible for three of them.
Javi Gracia, Quique Sanchez Flores and Nigel Pearson all lost their jobs to no avail, with the Hornets still suffering relegation.
This time, four clubs will start the season with a new manager – Patrick Vieira at Crystal Palace, Rafael Benitez at Everton, Nuno Espirito Santo at Spurs and Bruno Lage at Wolverhampton Wanderers.
After winning promotion, Brentford’s Thomas Franke and Watford’s Xisco Munez will take charge of their games in the top flight of English football.
