Spending his formative football years within one professional club gave him the opportunity to learn the technical and tactical aspects of the game through a structured academy environment.

His progress through West Ham’s youth ranks eventually brought him into the U18 setup. During the 2020–21 season, Casey made his U18 Premier League South debut. He continued developing during the following campaign and became a regular part of West Ham’s youth side, taking another important step toward professional football.

Rise Through the West Ham Academy

The 2021–22 season was an important stage in Casey’s development. He made 24 appearances for West Ham’s U18 side, including 23 starts, and scored his first league goal against Chelsea. His regular involvement demonstrated the increasing trust placed in him as a young defender.

West Ham eventually reached the final against Arsenal, winning 5–1, with Casey scoring during the impressive victory.

First Professional Contract

Casey’s performances at academy level helped him earn his first professional contract with West Ham United in June 2022. This was a significant milestone because it marked the transition from promising academy player to professional footballer.

Later that year, Casey received an opportunity to experience senior football. On 3 November 2022, he made his senior debut for West Ham against FCSB in the UEFA Europa Conference League.

His Premier League breakthrough finally arrived on 11 May 2024. Casey came on as a late substitute during West Ham’s 3–1 home victory over Luton Town. Making a Premier League appearance was another important achievement in his development and gave him valuable experience at the highest level of English domestic football.

Representing England at U20 level provided Casey with international experience against players from other footballing nations. His involvement at this level also reflected his progress as a young English defender and gave him another competitive environment in which to develop.

Swansea City Loan

In August 2025, Casey joined Swansea City on loan for the 2025–26 season. The move gave him an opportunity to experience more regular senior football away from his parent club.

He made his Swansea debut as a substitute against Middlesbrough and later made his first senior start for the club in an EFL Cup victory over Crawley Town. During his Swansea spell, he made 13 appearances across the Championship, EFL Cup, and FA Cup.

Leyton Orient Loan

After his Swansea spell ended, Casey moved to Leyton Orient on loan in January 2026. The move was designed to give the young defender additional first-team experience and opportunities to play regularly.

Casey made 16 League One appearances for Leyton Orient, including nine starts. Combined with his Swansea appearances, he recorded 29 senior appearances across competitions during the 2025–26 season, making the campaign an important period of practical experience.
