Having come up through the age groups at
LLanelli Town under the tutelage of former Welsh international
Leighton James, Mumford passed up a short-term contract offer from
Newcastle United in order to sign with
Swansea City (where James himself spent several years as a player) in the summer of 2000. Short spells on loan at
Haverfordwest County and
Port Talbot Athletic that season saw him gain further first team experience before he made his Swansea debut at
Port Vale in April 2001. The following season saw Mumford become a regular and end it as the clubs youngest ever player of the year as the team narrowly avoided relegation from the Football League. Several injuries curtailed his development however and following further loan periods to
Newport County and
Aldershot Town his contract was allowed to expire and he moved to
Australia to play for
Sydney FC in the inaugural
A-League season. After just one season in Australia he moved back to Wales, with stints at Welsh League teams
Port Talbot Athletic,
LLanelli Town,
Afan Lido and
Haverfordwest County before retiring in 2012. ==References==
