Whiteman joined the
Tottenham academy at the age of 10. In 2019, he signed a new three-year contract with the club. On 26 November 2020, Whiteman made his sole appearance for Tottenham when he was brought on as a substitute against
Ludogorets Razgrad in the
UEFA Europa League in the 82nd minute, replacing
Joe Hart. In April 2021, Whiteman
tore his meniscus, which he underwent surgery for. On 12 August 2021, Whiteman joined Swedish
Allsvenskan side
Degerfors on loan for the rest of the Swedish 2021 season. He returned to Tottenham after the Swedish season finished in December 2021. Whiteman began a second loan with Degerfors in February 2022, and returned to Tottenham in December 2022. On 22 February 2023, it was announced that Whiteman had signed a new 2-year contract with Tottenham. In August 2023, Whiteman suffered an ankle injury during Tottenham's
2023–24 season pre-season tour in
Singapore. After recovering from his ankle injury, Whiteman requested to go out on loan for the 2024–25 season, but was denied as Tottenham needed to use him as a club-trained player for their upcoming
Europa League campaign, with sanctioning body
UEFA requiring clubs to include at least 4 club-trained players in their squads in order to partake in their competitions, a competition Tottenham would win with Whiteman being awarded a winner's medal. In October 2025, Whiteman retired from professional football, despite interest from different clubs, in order to further pursue his creative ambitions. ==Later career==
