"I feel happy and in some ways relieved that I am leaving behind a great squad that will push on under new management and take this club back to the Premier League.
"The last five years at Harmen have been incredible. It's a special club that was set up by Jon Hirshler, Marc Cohen and Simon Lyons 12 years ago. I have tried my best to keep the team together, to keep them challenging, and most improtantly to have a squad of players we could be proud of.
"It has been humbling working with Stuart Cohen, who is the heartbeat of Southgate Harmen. Big Stu runs the club the way every club should be run, and he knows that he and Harmen can rely on me whenever they need.
"Thank you to all the players I have managed over the last five years, and everyone involved at the club."
