A former youngster at Chelsea, Cox is an England Youth international who was promoted to the First Team at Brentford in the summer of 2022.
Cox joined The Blues, playing in the same group as Myles Peart-Harris, Lewis Bate, Tino Livramento and Jamal Musiala. He spent six years with the club before he was snapped up by AFC Wimbledon as an Under-14.
He progressed through to earning a professional contract aged 17. In southwest London, he worked under a former Brentford goalkeeper in Ashley Bayes. In this time, Cox earned a reputation for saving penalties and even got himself on the scoresheet a few times.
In the 2020 EFL Youth Alliance Cup, Cox was just 16 when he put in the ‘performance of the tournament’ when he saved a penalty and then scored a last-minute header to level the scores against Northampton Town U18s. He went on to save two spot-kicks in the shootout.
He followed this up with a penalty save and clean sheet against Oxford United U18s in the Semi-Finals and then got a late winner against Rotherham United U18s in the Final – a clearance from just outside his box bouncing over the opposition goalkeeper.
He helped The Wombles into the London Senior Cup Final with a penalty save in May 2021, which they went on to lose 2-1 to Tooting & Mitcham United. Despite appearing on the First Team bench 18 times during the 20/21 season, he left the club to join Brentford’s B Team in July 2021. He signed a three-year contract with a year option.
During an injury-hit spell for David Raya, Cox played backup to Álvaro Fernández throughout the festive period.
He is also capped for England at youth level after turning out for the Under-17 side in 2020. In June 2022, after being promoted to the First Team squad, he was named in England’s UEFA European Under-19 Championship squad for the tournament in Slovakia.
