A star of the prestigious Hale End academy, Thompson rose through the youth ranks at the Gunners before signing his first professional contract at Arsenal in June 2018. He soon traded sides of the English capital, signing for then Championship outfit Brentford in 2019. Loan spells at Swindon and Ipswich Town followed before signing permanently for fellow Championship side Blackpool in 2022.

The left-sided defender has already made over 100-appearances across the English footballing pyramid, including two in the Premier League, with the 24-year-old completing the first-half of the 2024/25 campaign on-loan to Forest Green Rovers.
