Arthur, a 2023 signing from Peterborough United, made his debut in the Carabao Cup against Aston Villa last month.
After two seasons with Brentford's B team, Arthur is proud to be part of Keith Andrews' senior squad.
He credits the club's dedicated development system for his progress, saying it provided a clear plan from day one of pre-season.
Arthur set targets for himself at the start of the season and is happy to have achieved his debut.
He also believes that his experience playing against elite European teams in the B team has helped him prepare for his senior debut.
