Leo Alexander Francis Castledine (born 20 August 2005) is an English professional footballer who plays as an attacking midfielder or wide midfielder for EFL Championship club Middlesbrough.
Club career
Early career
Born in Kingston upon Thames, where he lived only 15 minutes away from the Cobham Training Centre, Castledine started his career with Chelsea, who he had supported growing up.[3] He spent two years with Chelsea before moving to AFC Wimbledon at the age of seven.[3] Growing up, he also played rugby, and was enrolled in the elite academy of professional club Harlequins.[3]
Initially beginning his career with Wimbledon in a more defensive role, he moved up the pitch to operate as a midfielder.[4] Settling into his new role well, he was involved in Wimbledon under-18's pre-season tour of Italy, playing alongside players four years his senior, and went on to make his under-18 debut in 2019 - becoming the youngest Wimbledon player to ever do so.[4]
Chelsea
A year later, in March 2020, he rejoined Chelsea, naming Mason Mount and Jack Grealish as his favourite current players.[4][5] He signed his first professional contract with The Blues in August 2022, on his seventeenth birthday, and has already been called up to train with the first team.[3][6]
Castledine made his senior debut for Chelsea as a substitute in a 6–1 EFL Cup semi-final second-leg win over Middlesbrough on 23 January 2024.[7]
Shrewsbury Town (loan)
On 26 August 2024, Castledine joined League One side Shrewsbury Town on a season-long loan deal.[8][9] He made his debut for the club the next day on 27 August 2024, in a 2–0 defeat to Bolton Wanderers in the EFL Cup.[10] He scored his first goal for the club on 31 August 2024, in a 3–0 win against Leyton Orient.[11]
Huddersfield Town (loan)
On 1 August 2025, he returned to League One, joining Huddersfield Town on a season-long loan.[12][13] He made his debut for the club on 13 August 2025, in a 2–2 draw with Leicester City in the EFL Cup which Huddersfield won on penalties.[14] He scored his first goal for the club on 26 August 2025, in a 1–1 draw with Sunderland.[15] Having scored five goals in his final month with the club prior to his recall, he was named EFL League One Player of the Month for December 2025.[16]
Middlesbrough
On 9 January 2026, Castledine signed for Championship side Middlesbrough on a four-and-a-half year deal for an undisclosed fee, reported to be a little under £1 million.[17][18]
International career
Castledine has represented England at under-15, under-17 and under-18 level.[2]
On 15 November 2023, Castledine scored on his England U19 debut during a 6–0 win over Romania in Marbella.[19]
Personal life
He is the son of former Wimbledon footballer, and television presenter, Stewart Castledine, as well as former Homes Under the Hammer host Lucy Alexander.[3][20] Leo has an older sister, Kitty, an actress who currently stars in EastEnders.
