Gillingham manager Mark Stimson has left the club by mutual consent following their relegation to League Two on Saturday.
A 3-0 defeat by Wycombe saw the Gills slip into the relegation zone on the final day, finishing fourth bottom.
Stimson, 42, guided the club to League One via the League Two play-offs in 2009 and started the current campaign with a 5-0 home win over Swindon.
But a failure to win a single away game this season sealed Gillingham's fate.
"There didn't seem to be any formula for getting a win away from home and really that is what has caused the relegation," chairman of the Gillingham Independent Supporters Club Gary Liptrott told BBC Radio Kent.
"He's the one who bought the players in. The majority have played throughout the season and whatever tactic he's used away from home just hasn't worked."
Former Gills boss Andy Hessenthaler, 44, has been linked with a possible return to league management after guiding Dover to the Blue Square South following two successive promotions.
Speaking prior to Stimson's departure, he said: "I've made no secret of the fact that I miss the day-to-day involvement of full-time football and one day, in the not too distant future, I would like to return.
"The Dover chairman [Jim Parmenter] knows that I would like to return to full-time football. So it's no secret."
Ex-Newcastle and Portsmouth defender Stimson took over as Gills boss in 2007 after a successful managerial spell in non-league football.
Under his leadership, Grays Athletic were promoted to the top-flight of the Football Conference where they won two FA Trophies, a cup that Stimson won for the third year in a row after taking over at Stevenage.
Following Gillingham's poor start to the 2007-08 League One campaign under Ronnie Jepson, Stimson was drafted in as a replacement but failed to halt the side's slide into League Two.
A 1-0 play-off final win against Shrewsbury marked an immediate return back to League One, but the joy was short-lived after just one season and the poorest away record in the Football League.
