[29] Reflecting on the decision to let him leave the club, manager Nigel Clough said that "it would have been very, very selfish" to insist that he stay at Field Mill when he could not guarantee him much playing time.

[33] He played as a substitute in the play-off final at Wembley Stadium as Vale secured promotion with a 3–0 victory over Mansfield Town; Michael Baggaley of The Sentinel wrote that "[Charsley put in] a typically dynamic performance against his old club".

[42] On 2 July 2024, Charlsley joined National League club Oldham Athletic on a two-year deal after manager Micky Mellon worked hard to tempt him to drop into non-League football.
