Thomas van Bommel

MVV

Van Bommel made his professional debut for MVV in the Eerste Divisie on 22 September 2020, coming on as an 88th-minute substitute for Jelle Duin in a 2–0 loss to Den Bosch. On 30 October, he replaced Kai Heerings with four minutes to play against Helmond Sport and scored his first professional goal to equalise in a 1–1 away draw.

Patro Eisden

On 1 May 2023, it was announced that Van Bommel had signed with Challenger Pro League club Patro Eisden Maasmechelen, joining the club as a free agent from 1 July 2023. After failing to make an appearance for the club, he was sent on loan to Sporting Hasselt for the remainder of the season. In July 2024, Van Bommel was sent on a one-season loan to Bocholt VV. He missed most of the 2024–25 season with a groin injury, ultimately appearing only in the final four matches.

Tongeren

Ahead of the 2025–26 season, Van Bommel joined Belgian Division 2 club Tongeren, filling the central-midfield vacancy left by the departure of Oleg Kuchinska. In September 2026, he announced his provisional retirement from football due to a recurring injury.
