Essex born and raised, Academy of Football graduate Kaelan Casey has been with West Ham United since the age of five.

The 2022/23 season saw tall centre-back Casey make his breakthrough, with a senior first-team debut in a UEFA Europa Conference League win over FCSB in Romania in November 2022 being followed by U18 Premier League South and FA Youth Cup glory in the spring of 2023.

Casey followed those achievements by captaining the U21s to runners-up in Premier League 2 in 2023/24, and he trained regularly with the first-team squad throughout that season and the next, making his Premier League debut against Luton Town at London Stadium in May 2024.
