The 22-year old attacking midfielder began his career as a youngster at Fulham before making the move to Bristol Rovers at the age of 16.
While with the Pirates, he made his professional debut in an EFL Trophy clash at Exeter City in 2018 before making his league debut in a trip to Doncaster Rovers in League One in September 2020.
Walker went on to make a total of 11 league appearances and 18 in all competitions while at the Memorial Stadium whilst taking on loan spells with King’s Lynn Town and Chippenham Town in 2021.
He joined King’s Lynn in the National League permanently for the 2022/23 season, before joining up with Aldershot Town last summer.
Last season saw him enjoy a pair of successful loan spells with Bishop’s Stortford and he now arrives in DA16 as Rod Stringer begins to build his squad for the 2024/25 campaign.
