Thompson signed for the Mariners in February 2024, becoming one of David Artell’s first signings since his arrival as Head Coach towards the back end of 2023.
Thompson began his career with Leicester City before joining Notts County. During seven years at Meadow Lane, Thompson made over 100 appearances for the Magpies, many at League One level.
Following a successful loan spell with Wycombe Wanderers, the midfielder signed for the Chairboys permanently ahead of the 2018/19 campaign and helped them win promotion from League One in 2020 and was a regular in their side during their season in the Championship.
After four seasons at Wycombe, Thompson made the move to Cheltenham Town in the summer of 2023 and made 22 appearances for the Robins during the campaign before joining the Mariners on the 1st February 2024.
