Date of birth
CALLUM went to school at Brixham College, following in the footsteps of ex-Pilgrim Dan Gosling nine years before him.
After spending time at Aston Villa's Academy and playing local junior football with Brixham and Marldon in the Pioneer League, the promising centre-back joined Argyle's Academy in the 2014-15 season.
He went on to play a significant part in the club's Youth Alliance League and South West Peninsula League successes. Alongside contemporary Alex Fletcher, Callum was an unused substitute in the FA Cup third-round replay against Premier League Liverpool, and, also like Fletcher, signed his first professional contract with the club six months later.
