Hamburg-born Noah Ajayi moved to England, aged 10, with his father, and later signed for Manchester United, before signing his scholarship, aged 16, in 2025.

Noah made his Under-21s debut for United in April 2025, coming on as a substitute against Reading in a 3-0 victory. The next day, he made his Under-18s debut, again as a late introduction off the bench, this time in a 3-0 triumph over Nottingham Forest. He made one further U21s appearance before the season’s end.
