Left-back Tom Hanfrey joined the Cherries in 2017 following a successful trial spell.
Born in London and schooled at Beths Grammar in Bexley, he was previously on the books at Millwall and Charlton Athletic.
In 2018/19, he played his part as the Cherries reached the quarter-final of the FA Youth Cup – the club’s best run in the competition for 50 years.
Hanfrey featured in wins against Mansfield, Oxford United and Aston Villa and scored a stunning volley in the last-eight encounter as the Cherries bowed out against eventual runners-up Manchester City at Vitality Stadium in February 2019.
He was rewarded with his first professional contract after completing his two-year scholarship at the end of 2018/19.
Hanfrey, who has trained with Eddie Howe’s first-team squad, has had loan spells with Southern League South outfits Poole Town and Farnborough.
