During 1994 and 1995, Bradley was successful in a number of trials and was selected to play for the England schoolboys squad for the Victory Shield matches against Northern Ireland, Scotland and Wales, as well as friendlies against Brazil and Germany.
After a meeting with Southampton manager Glenn Hoddle, Bradley decided to move to Mansfield Town to get more first team games.
Shayne started his Mansfield career well, scoring nine goals in his first half season and striking an effective partnership with Chris Greenacre.
In the build-up, he expressed the opinion that he did not think that Watkiss rated him as a player and that the club had treated him badly by playing him when he was not fully fit.
[12] Bradley retired at the end of the 2002–03 season after a double reconstruction of his right ankle and returned to his home town of Gloucester.
In July 2008, he was appointed manager of Tuffley Rovers in the Gloucestershire County League, although continuing his work with Gloucester.
