Crew started his career at Cardiff City, where he played in the club's academy from the age of seven. In 2022, he transferred to Leeds United for an undisclosed fee, joining the club's under 18s initially, before being promoted to the under 21s in January 2023.[4][5] Crew spent the 2023–24 season with the Leeds Under 21 team and was called up to the first-team squad for the first time on 29 March 2024, where he was an unused substitute against Watford.[2]
Crew also represented the Leeds United Under 18 Team in the FA Youth Cup throughout the 2023–24 season and scored one of the goals in the 4–3 semi-final win over Millwall Under 18s to seal Leeds' place in the final.[6]
On 12 July 2024, Leeds United announced that Crew had signed a long-term deal with the club, through to 2028.[7]
Crew has represented Wales at Under 15, Under 16, Under 17, Under 18 and Under 21 levels. He has captained his country at each of these levels, up to and including Under 18. In 2021–2022, Crew was the captain of the Wales squad that won the Victory Shield. Crew was named as captain of the Wales Under 17 squad for the 2023 UEFA European Under-17 Championships, held in Hungary.[9] In 2023, he was called up to the Wales national under-21 football team[10] despite being just 16 years old, leading him to be labeled as a 'prodigy' by the Yorkshire Post.[11]
Crew has family from England, and in October 2023 officials from The Football Association were reported as expressing an interest in having Crew represent England instead of Wales.[12][13]
In May 2024 Crew was called up to the Wales senior squad for the first time.[14] Crew made his debut for the Wales national team on 6 June 2024 in a friendly against Gibraltar at the Estádio Algarve in Portugal. He substituted Charlie Savage in the 78th minute as the game ended in a scoreless draw.[15]
