Patrick Kelly has signed a new deal with West Ham to 2026.
Hammers football chief Mark Noble says the youngster deserved his new contract.
Noble told the club's website: "Since signing for the Club in 2022, Patrick has embodied the Academy's core values of hard work, determination, and humility.
He has settled in really well and that has shown through his performances on the pitch, where he has been a key part of the Under-18s success last season and carried that into Under-21 level this year.
This new contract is a sign of the Club's faith and belief in Patrick, but also a challenge and an incentive for him to continue his progression and prove that he can go up another level higher.
It is now up to Patrick - as it is with the other young professionals to have signed new contracts this season - to keep showing the same hunger, commitment and determination, in order to reach the next step on the ladder and climb even further.
We look forward to seeing how Patrick will respond to the challenge in front of him - he is highly thought of by everyone here and we are delighted that he will continue his progress with West Ham United."
