In February 2003, 15 year old central defender Adam Gusterson made the record books when he became the second youngest player to play for Norwich's Reserve team. The youngest player to achieve this is Gusterson's Under-15 colleague Rossi Jarvis. A regular in the Under-15s, Adam was called up for the reserve team clash with Brentford on 5th February 2003 as Norwich's youth team were playing the same day against West Ham in the FA Youth Cup. Many of the regulars in the reserves were playing for the youth team.

Although much of the 2003/4 season was hampered by a serious knee injury that had to be reconstructed, Adam joined the Norwich City Academy as a full-time scholar in July 2004. Academy Director Ricky Martin said "Adam's one we use as an example to the young schoolboys in terms of what's required of them passing-wise, short and long, off both left and right foot -something that he's only achieved through a lot of hard work."

Unfortunately Adam was not offered a professional contract by the Canaries in April 2006 and spent the remainder of the 2005/6 season with Kings Lynn. He then joined the Linnets for pre-season training but was not guaranteed first team football so he left to join Robert Taylor's Dereham Town on 27th July 2006

In february 2008, Adam was named as Dereham's manager until the end of the 2007/8 season following Robert Taylor's sacking. His reign as caretaker manager at Dereham Town got off to a good start as the Magpies swept aside Ridgeons Premier bottom club Newmarket Town 2-0 at Aldiss Park in front of a 137 crowd. Gusterson also works for Norwich City as a Football In The Community coach
