Aaron Henry joined Charlton at the age of 10.
In January 2020, the then-16-year-old became the third youngest ever player to make his senior debut for the club as he enjoyed 60 minutes of the Addicks' FA Cup tie against West Bromwich Albion at The Valley.
The midfielder, who has been capped by England at youth level, signed his first professional deal with the club in October 2020, committing his future to Charlton until at least 2023. Since then, Henry has enjoyed a handful of first-team appearances.
Henry enjoyed an impressive loan spell with National League outfit Wealdstone in the latter half of the 2021/22 campaign, recording eight assists and a goal in his first 10 appearances for the Stones to see his loan spell extended until the end of the season.
In May 2023, the academy graduate penned a new two-year deal with the club with the option for a further year.
Henry joined League Two side Crawley Town on loan for the 2023/24 season in August 2023.
The midfielder was recalled from Crawley in January 2024 to return to Wealdstone on loan for the remainder of the 2023/24 campaign.
