Gavin joined Enfield Town ahead of the 2023-24 campaign after parting company with Metropolitan Police FC, where he spent over twenty years as a player, assistant, and manager. Following a playing career for Barnet and Carlisle, as well as spells at Wealdstone, Slough Town and Woking, Macpherson took the managerial reins at the Met for the 2018-19 season after the resignation of Jim Cooper, guiding them to victory in the Southern League play-offs – only to be denied promotion at the final hurdle against Tonbridge Angels in a ‘Super Play-off’. A widely-regarded coach who has gained a reputation for moulding highly competitive squads, often with young players, he guided the Towners to the National League South in 2024 via the Isthmian League play-offs during his first season in charge.
