And now the England national team’s all-time top goalscorer has been rewarded with the job permanently.
The 35-year-old has signed a two-and-a-half year contract with Derby, set to keep him at the club until 2023.
Joining him in his backroom staff will be assistant manager Liam Rosenior, first-team coach Shay Given and development coach Justin Walker. All three were working with Rooney during his interim period.
Rooney replaces Dutch manager Philip Cocu in charge at Pride Park. Cocu departed the club by mutual consent back in November, after a late 1-0 defeat to Queens Park Rangers left them rock bottom of the table, having won just once in their opening ten fixtures.
In line with his promotion to the managerial position, Rooney has officially retired from his playing career.
He leaves behind an astonishing legacy, as Manchester United and England’s all-time leading goalscorers.
The forward is one of only two players to have netted over 200 Premier League goals, and boasts five Premier League titles and a Champions League winners medal among other honours.
