Neil Harris has resigned as Millwall manager after four and a half years in charge of the south London club. 


The 42-year-old was the longest-serving manager in the Championship and was seventh in all four of England's top divisions. His assistant, David Livermore has also stood down from his role. 


Harris joined Millwall initially as caretaker boss following Ian Holloway's departure in 2015 and managed 246 games since then, winning 103. 


Millwall's leading top goal scorer took the club to two consecutive League One play-off finals, two FA Cup quarter-finals as well as leading them to an 8th placed finish in their first season back in the Championship. 


The news came in a shock announcement exactly 24 hours after their 1-1 draw with away at Luton in midweek. 


In a statement, the clubs chairman John Berylson said: 

"Firstly I would like to place on record my sincere gratitude to Neil for all of his hard work, commitment, determination and inarguable success as manager of this great football club.


“During his time in charge we have achieved so much and so many of his greatest moments as manager will live long in the memory of all Millwall fans fortunate to have seen and enjoyed them.


“Neil’s achievements ensure that he is listed alongside some of the club’s greatest-ever managers, furthering his legendary standing at Millwall.


“Neil’s name is synonymous with Millwall and he has always had the very best interests of the club at heart, managing with great pride, hounor, and integrity, and he departs with the best wishes of everyone connected with The Lions.


“Both Neil and David leave with their heads held high, forever friends of the club, and I wish them both every success in their future careers. They will always be welcome at The Den." 


Adam Barrett has been appointed as caretaker manager for Millwall's fixture against Leeds United on Saturday as the club has said it is not carrying out a thorough recruitment process for Harris' replacement.
