During his time at Manchester United, he had a significant loan spell with Wrexham, playing a crucial role in their historic FA Cup victory over Arsenal in January 1992. In November 1993, Carey transferred to Leicester City, where he made 58 league appearances and was part of the squad that secured promotion to the Premier League in 1994, defeating Derby County in the play-off final. He then moved to Wrexham permanently in 1996, where he spent nine years as captain, making 288 appearances and scoring 15 goals before retiring due to injury in July 2005. Transitioning immediately into coaching at Wrexham, Carey took temporary charge of the club in January 2007 and successfully guided them to avoid relegation from the Football League with a decisive 3-1 victory against Boston United on the final day, subsequently earning a permanent two-year managerial contract.
In April 2022, Carey joined Reading Football Club as their Director of Recruitment, a key strategic leadership position. In this role, he works collaboratively with Head of Football Operations Mark Bowen, manager Paul Ince, and Academy Manager Michael Gilkes to identify, assess, and integrate new talent into the club’s structure, applying his deep understanding of player development and strategic squad building to secure top-tier talent.
