Having made over a hundred league appearances for both Sheffield United and Portsmouth, David Munks played no more than twenty times for Exeter City before a knee injury ended his professional career. Signing from Swindon, he later played on a semi-professional basis for Waterlooville.

David won England Youth caps whilst with Sheffield United for whom he had 112 league outings before moving to Portsmouth in July 1969 where he was player of the year in 1971 and made 137 league appearances. Financial problems at Fratton Park saw him depart for Swindon Town in December 1973 but he was to feature in just 21 league matches in Wiltshire before joining Exeter City on loan in January 1975.

Making his debut for the Grecians in a 1-0 home win over Hartlepool on 4 January 1975, David made eleven appearances during the rest of the season before earning a permanent move to St James’ Park in the summer of 1975. Soon sustaining a knee injury, David didn’t play until the December 1975 fixture against Huddersfield which proved to be a start of nine successive appearances leading up to the recurrence of the injury in January 1976 which resulted in the end of his professional career.

Leaving City in the summer of 1976, David returned to the Portsmouth area and briefly turned out for Waterlooville before working in sports centres in both Portsmouth and Southampton.
