How do Premier League managerial changes compare to other seasons?

Liam Rosenior's sacking by Chelsea this week took the number of top-flight managerial departures this season to 10.

It's at the higher end of the scale in terms of Premier League history, but still well short of the record, set in 2022-23, when there were 14 exits during the campaign.

What is notable, however, is the condensed number of clubs involved, and the lack of time given to those managers who didn't leave of their own accord.

In 2022-23, 11 different teams – more than half of the top flight – changed their manager; this season there have been just six clubs involved, with half of those doing so more than once.

Tottenham and Chelsea have both changed managers twice, while Nottingham Forest are on their fourth of the season. It's just the second time – after 2022-23 – that three different Premier League clubs have made at least two managerial changes in a season.

In 2022-23, the managers leaving their jobs had been in position for almost twice as long as those who have left this season.

While not all departures that season were a one-way thing – for example, Graham Potter chose to leave Brighton for Chelsea – it's generally still noticeable how much more time managers were given before clubs took action.

Javier Gracia's reign at Leeds was the most short-lived in 2022-23. Brought in with the task of saving the Whites from relegation, he was sacked after 10 weeks and Sam Allardyce, who had history of saving clubs from relegation brought in for the final four games.

Meanwhile, Nathan Jones lasted just three months at Southampton but all the others who left their job in that campaign had been there for at least six months.

This season, almost half of those going have gone before the six-month mark, including Ange Postecoglou, who was axed after a record 39 days and Igor Tudor, who was despatched after 44 days. Only three had been in their role more than a year. The average time served was 9.1 months, compared to 17.5 months in 2022-23.

In 2022-23, multiple chopping and changing work didn't pay off for those clubs involved. Leeds and Southampton were both relegated, while Chelsea finished 12th.

In terms of this season's serial changers, Forest look safe but Chelsea look set to miss out on the Champions League while Tottenham could be relegated for the first time for almost half a century.
