Neil Harris is the former manager of Cardiff City and Millwall.
Harris, who is Millwall's all-time record goalscorer, took charge of The Lions on a caretaker basis in March 2015 following the departure of Ian Holloway.
The former striker was unable to save the club from the dreaded drop out of the Championship but was handed the job on a permanent basis at the end of April.
Millwall went on to enjoy a very decent 2015/16 season, finishing 4th, but lost out in the play-offs. However, they stormed back the following season and returned to the Championship after winning the 2016/17 play-offs. He then resigned in October 2019.
