Average manager spell is 1.23 years
The instability of life as a football manager has been laid out in stark detail by the League Managers' Association, who on Friday revealed the average tenure in the English game is just 1.23 years.
For bosses in the Championship, where there were 20 dismissals in the recently-completed season, the average spell in charge is even lower, at 0.86 years.
There were 47 manager dismissals in the 2014-15 season, the most since the 2001-02 campaign when 53 were sacked.
Arsene Wenger continues to buck the trend, having managed Arsenal for 18.67 years and 1,065 matches.
LMA chief executive Richard Bevan said in the end of season review: "The numbers only serve to highlight that the game continues to present an increasingly more complex and volatile working environment for all the professional practitioners: the players, coaches and managers.
"If we are to see a significant change in the statistics within this report then the game and its leaders need to take a longer-term view and build stability."
Bevan, who highlights "short-termism" as one of the factors behind the changes, says 17 of the dismissed bosses were first-time managers who may find it difficult to manage again and more than 150 coaches lost jobs as a consequence of managerial changes.
There were 64 managerial changes up until May 31, 2015, with 17 resignations.
The 47 dismissals is 10 more than in the 2013-14 season and featured five in the Premier League, 20 in the Championship, 12 in League One and 10 in League Two.
The average term for a Premier League boss is 1.8 years, which is higher than in the other three divisions: Championship (0.86), League One (1.41), League Two (1.44).
The Premier League also has the highest average tenure of all current managers with 2.36 years. Championship (1.14), League One (1.44), League Two (1.67).
The next longest-serving boss after Wenger is Exeter's Paul Tisdale, who has been in charge for 8.93 years. Other Premier League bosses in the top 10 are Leicester's Nigel Pearson (3.54) and Liverpool's Brendan Rodgers (3.0), who are eighth and 10th, respectively.
Bevan says the LMA will work to support out-of-work managers and coaches to provide new employment opportunities as it can take up to two years to get another appointment.
The LMA also plans to help clubs with the recruitment process, which Bevan says is often rushed and results in suitable candidates being overlooked in favour of known ones.
The organisation also hopes for the imbalance of black and minority ethnic individuals in football management to be rectified.
Bevan said: "We fully support the introduction of a range of measures across the areas of education, recruitment, role models and mentoring with the aim of achieving a better balance between the proportion of BAME players and the current under-representation of BAME managers and coaches."
