Adam Flanagan and Jamie Coyle have left Dartford after a dreadful run of form stretching back to last season.
After guiding the Darts to just two wins in 17 outings, the duo’s departure was announced within hours of Tuesday night’s 3-2 defeat at Tonbridge in National League South.
Goalkeeping coach Andy Young and strength and conditioning coach Harrison Grant followed them out of Princes Park on Wednesday.
In a club statement announcing the latest departures, former manager and club director Tony Burman was named as interim manager as the hunt to make a permanent appointment began.
Wednesday’s statement read: “We are pleased to announce that Tony Burman will take interim charge of all first team matters until a new permanent manager is appointed. The club is already receiving expressions of interest from suitably qualified candidates and a formal recruitment process will begin in due course.”
Dartford co-chairman Dave Skinner told kentonline.co.uk: “They’re both stalwarts of the club and have got the club at heart – the same as we have. They’re going to move on and we’ve got to pull it together again.
“They had a target to meet and they haven’t reached the target. We changed the squad from last season. On paper the squad is very good but somehow it just hasn’t worked.
“Everyone says it’s more money. The budget has been slightly increased but only a cost of living increase, that’s all – nothing major. For the quality of the squad we’ve got, we’d expect to be higher up than we are.”
The duo were appointed joint-managers in May 2018, succeeding Burman who was in charge for over a decade and guided the club to the top flight of Non-League.
The Darts are currently third from bottom and Skinner added: “It’s a massive job to try and follow somebody like Tony. They’ve been unfortunate because a lot of things have gone wrong for them.
“Everyone just blames them and they take the blame but so many things have gone wrong over the course of this year and last year. Injuries, decisions going against us, but ultimately they take the responsibility.”
Flanagan told fans on Twitter: “Jamie and myself resigned after the game. We notified the players and then Steve, Dave and Tony. Dartford is a great club. I have loved being back but we always said we would put the club first and the results haven’t been to the required level.
“We have disappointed fans and that’s the last thing we wanted to do. I wish the greatest of success to the club going forward and I will be back over to watch and encourage at some point in the future.”
