Pritchard began his football career at the youth academy of Tottenham Hotspur, where he spent several years developing his skills. He made his senior debut for the club in 2014 but struggled to secure a regular spot in the first team. As a result, Pritchard was loaned out to several clubs, including Brentford, Swindon Town, and West Bromwich Albion, in order to gain more playing time and experience.
