Rooney's first taste of management came in November 2020 where he was entrusted with attempting to steer Derby County away from relegation from the Championship following the dismissal of Phillip Cocu. Already in place as a player-coach at Pride Park, this was his big chance - and he didn't make a bad fist of it.
Rooted to the bottom of the table and in their lowest league position for 12 years, Rooney took charge, first as part of a four-man interim team before getting the job permanently in January 2021, and would go on to settle for 21st place. Relegation avoided, mission accomplished - just about, it must be said, with the Rams surviving by a single point.
