Championship clubs are preparing for the 2023/24 season, with all 24 managers and head coaches now in place.
Sunderland boss Tony Mowbray is preparing for his first full campaign in charge on Wearside, after taking over at the Stadium of Light in August last year.
There have been several managerial changes in the second tier since then, with some clubs going through three bosses last term.
We’ve taken a look at the longest-serving managers and head coaches in the Championship:
5. (20th) Michael Duff (Swansea) - 19 days
The departure of Russell Martin, who joined Southampton, left Swansea looking for a new head coach this summer. They opted to appoint 45-year-old Duff, who took Barnsley to the League One play-off final last season. Photo: George Wood
6. (19th) Russell Martin (Southampton) - 19 days
After two years at Swansea, Martin, 37, has moved to Southampton, signing a three-year deal at St Mary’s. Photo: Ryan Hiscott
7. (18th) Erol Bulut (Cardiff) - 1 month
While former boss Sabri Lamouchi kept Cardiff in the Championship last season, The Bluebirds opted not to offer the Frenchman a new contract. Cardiff then appointed 48-year-old Bulut, who had previously managed in Turkey. Photo: OZAN KOSE
8. (17th) Gareth Ainsworth (QPR) - 4 months
After starting last season as play-off contenders, QPR became relegation candidates in the second half of the campaign. Former player Ainsworth, 50, was appointed in February and managed to keep the club up. Photo: Alex Livesey
