Theo Gary Carlstan Vassell (born 2 January 1997) is an English professional footballer who plays as a defender for EFL League Two club Barrow.
Vassell grew up in Stoke-on-Trent and played Ladsandads football for Hanley Town before joining the Academy at Stoke City at the age of nine.
[10] Four days later he joined National League side Chester on loan until January 2017, alongside "Saddlers" teammate Liam Roberts.
[15][16][17] He played a total of 32 games as the "Seals" posted a 19th-place finish in the National League, but was told by Whitney that he would not be retained upon his return to the Bescot Stadium in May 2017.
[21] He made his debut in the EFL Cup on 14 August, in a 4–0 defeat to Lincoln City at Vale Park, though he entered the game as an 85th-minute substitute for Cristian Montaño with the "Valiants" already four goals down.
[26] On 1 February 2020, it was announced that he was one of three players to have left Macclesfield during the January 2020 transfer window, following a meeting with the English Football League.
[29] Manager Dean Keates said that Vassell would learn a lot playing next to club captain Shaun Pearson in defence.
[31] On 12 November 2021, Vassell signed a short-term deal with League Two side Salford City after having trained with the club for several months and recovering from tendonitis.
[37] He scored his first goal of the 2023–24 season in a 3–1 win at Wrexham on 3 February after having recovered from an injury lay-off to form a strike partnership with Curtis Tilt.
[41] He scored three goals in the first ten games of the 2024–25 campaign, and his strike in a 2–0 victory against Newport County put the Bluebirds to the top of the table on 21 September.
[45] On 25 January, he scored in a 3–0 win over Grimsby Town at Holker Street to secure himself a place on WhoScored's top five performers in Sky Bet League Two.
