Leacock expressed his gratitude to the West Ham United staff and players for making his transition to the team easy. He has been training with the team for around seven weeks and has been impressed by the level of support and guidance he has received. Leacock's experience at Linfield in Northern Ireland was different, with a more limited training schedule. However, he has adapted well to the demands of training with West Ham United every day.

Leacock started his football journey at his local club, Magherafelt Sky Blues, before joining Linfield at the age of ten. He made his first-team debut for Linfield against Larne FC in April. Leacock's signing of a new contract with West Ham United is a significant milestone in his young football career.
