Marconi Stallions in the
NSL before trying his luck overseas where he had short stints with
Scottish club
Stirling Albion and
Malaysian Super League side
Pahang FA. A series of impressive performances during
Perth Glory's 2007 pre-season trip to
Malaysia secured a place for Mitchell on the club's list for the 2007-08 season. Prentice left
Perth Glory at the end of the 2007/08 season, after failing to negotiate a new contract. He was signed by
Sydney FC for the 2008/09 season, on a 2-year deal. He scored his first goal for Sydney in their first 2008 preseason cup game against
Queensland Roar at

Seo Hyuk-Su being sent off for a sliding tackle against Sydney's
Alex Brosque. Prentice played his first A-League match as a Sydney FC player on 30 August 2008 at the Sydney Football Stadium against his old club Perth Glory. Prentice played the full match in which Sydney FC won 5-2. Prentice decided to end his contract 3 months early with the Sky blues in early 2010. ==Coaching career==
