First team coach Mark Newson has agreed to stay for another season, his fourth at Crabble.
The 57-year-old former Bournemouth and Fulham captain took charge again at Dover’s first pre-season training session at K Sports Cobdown on Saturday.
Newson, a youth team coach at Premier League Crystal Palace, made almost 200 appearances for Bournemouth and led them to the Division 3 title in the 1985/86 season.
He was also assistant manager at League One Stevenage Town in 2012/13.
