Greygoose joined Bury Town during the 2006-07 season, and played for the club until retiring in July 2009 and working as a goalkeeping coach at Bury Town, and as joint manager of Team Bury.

In June 2012 he joined Kettering Town FC as assistant manager to John Beck and goalkeeping coach. He has also been Assistant Manager at Histon and Ely City, goalkeeping coach at Crewe, Cambridge and Ipswich's Academy as well as Manchester City's community programme.
