Improved results soon followed, and he lead a drive up the League table including a number of high profile wins against high placed sides and a good run in the FA Trophy, including victory at Forest Green Rovers.

Danny was formerly a coach at Northampton Town, where he met Paul Curtis, and had a successful playing career in non-league football with clubs such as Boreham Wood and Bedford Town.
Spells at Hemel Hempstead Town and Corby Town have followed since.
