David Dyson can proudly boast that he was on the Norwich City substitutes' bench for the clash with Bayern Munich. Unfortunately this was not the famous UEFA cup victory but rather the friendly that occurred on 28th January 1992. Injuries to Bryan Gunn and an FA Youth Cup tie for Andy Marshall meant that City's "B" team keeper David Dyson was called up as understudy to Mark Walton . David did not get to play but the experience was invaluable considering that most of his goalkeeping career had been in the Essex and Herts Border Combination Youth League with Norwich's B team or with Lakeford Rangers in the Anglian Combination.

David was born in Hertfordshire at Hemel Hempstead where his local professional side was Watford. Indeed his father Bertie was offered professional terms with them but rejected them in favour of the security offered by a career in banking. The Dysons moved to Norwich when David was 12 and he began to attend the Canaries' Centre of Excellence at Trowse. He joined Poringland Wanderers' junior side alongside Phil Mortimer and helped them win the Under 17 Canary Cup. He also played for Poringland's senior side.

David later played for Wroxham and Wycombe Wanderers before signing for Dr Martens League side Burnham where he spent 7 seasons. In the summer of 2001, he joined Mangotsfield but the following July, he moved again to join Clevedon Town. By the following December, he was playing for Nick Tanner's Welton Rovers in the Screwfix Premier Division.

In January 2005, David returned to Burnham having last played for them in January 2000 at Erith & Belvedere where he broke his leg.
