Josh Cullen has told BBC Radio Leeds he is determined to become a success at West Ham.
Midfield ace Cullen is currently on loan at Bradford City and has impressed since joining in January.
Bradford are battling to win promotion to the Championship, and the teenager is gaining valuable experience, with Hammers teammate Reece Burke another loan regular for the side, playing at centre-back.
Cullen, 20, said: "I am hopefully making the steps to break through at West Ham. That's the goal as I've had ever since I remember, growing up wanting to play for West Ham.
"At the moment I am just focusing on the rest of the season with Bradford, and getting us promoted."
He added that West Ham's coaching staff have been in regular contact with him about his progress, which gives him further encouragement.
Cullen said: "It's a great club, they haven't just let me come out and taken no notice of me."
The youngster is a Republic of Ireland under-21 international, but represented England at under-16s.
He has made 10 appearances for Bradford so far, providing one assist. Earlier in the season he played in three Europa League qualifying games for West Ham, and made his debut in the Premier League in August, coming on the final minute away at Liverpool, but has not featured since, but signed a two-year contract extension days later.
Prior to being loaned out he had scored four goals and provided four assists in 12 games for West Ham's under-21 side, and clearly needed a new challenge at competitive first team level.
Bradford are currently in fifth place in League One, and Cullen could come up against West Ham's rivals Millwall in the play-offs.
