Callum Leacock joined West Ham United on scholarship terms from Linfield, where he spent the past seven years developing within the academy of the Northern Ireland Football League champions.

Capable of playing at centre-back or full-back, Leacock is also a talented Gaelic football player. He concluded his time with Derry-based O’Donovan Rossa GAC Magherafelt with a man of the match performance in his final game for the club, the Ulster U16s final.

Leacock has also impressed at international level, making his Northern Ireland U17s debut in October 2023 and going on to feature in all 16 of their following fixtures.

An international at U19s level as well, Leacock signed his first professional contract on his 17th birthday in August 2025, captained our U18s in his first season in Claret and Blue and featured a further eight times for the U21s. He also started the U17 Premier League Cup final as our young Hammers defeated Blackburn Rovers 3-2 at Wham Stadium.
