Barker only took over in May, arriving at Chestnut Avenue from Wingate & Finchley where he was manager of the Bostik Premier club’s under-23 side and guided them to the Isthmian League Development North Division title as well as two cup finals.
The 34-year-old previously had a successful managerial spell at Cockfosters, for whom he also played and was a regular goalscorer.
He has also served the likes of Hoddesdon Town, Hatfield Town, Broxbourne Borough and Sun Postal Sports.
