Career
An AIS graduate, he played with Northern Spirit and Marconi Stallions in the Nationaal Samenwerkingsprogramma Luchtkwaliteit 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 2007-2008 season. During the 2007-2008 season, Prentice was convicted of assault after attacking a patron at a Perth restaurant. Prentice left Perth Glory at the end of the 2007/08 season, after failing to negotiate a new contract.
He was signed by Sydney Football Club for the 2008/09 season.
On 3 May 2008, Prentice signed a 2-year deal with Sydney Football Club. He scored his first goal for Sydney in their first 2008 preseason cup game against Queensland Roar at Campbelltown Stadium in their 2-1 Victory. He scored off the free kick that resulted in Queensland"s 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 Football Club player on 30 August 2008 at the Sydney Football Stadium against his old club Perth Glory. Prentice decided to end his contract 3 months early with the Sky blues in early 2010.
Mitchell now runs a football coaching business (P2P Football Academy) aimed at youth development.
At (Prepared to Play) the focus is on key technical aspects of football for young players aged 8–14 years of age. P2P enhances each individuals skill level and helps young football players progress to a higher level through practicing game relevant skills and techniques. Outlined in each training session are the four core skills from the Future Farmers of America curriculum which are met in realistic game situations.
The program is currently being run in conjunction with Melville City Football Club, the largest football club in Washington.
