He was appointed as assistant manager of Swindon Town in 2021 before being made assistant coach at Charlton Athletic in 2022. Playing career Marshall started his playing career at Arsenal and broke into their first team at the age of 19, winning five Scotland under-21 caps. He scored his only goal for the Gunners in their 2–0 victory over Newcastle United in March 1996 and at the end of that season was voted as Arsenal's Young Player of the Year by the supporters. In seven seasons with Arsenal he only made 27 appearances, spending spells on loan at Rotherham United, Oxford United and Sheffield United. He made three league appearances as Arsenal won the 1997-98 Premier League, however this was not enough to qualify for a winners' medal. In August 1998, Dave Jones signed him for Southampton on a free transfer. Saints thought they had made a transfer coup, but Marshall soon showed why Arsenal let him go, scoring an own goal in his debut against Leeds United in a 3–0 defeat on 8 September 1998, repeating this four days later in a 4–0 defeat at Newcastle United. He never appeared again for Saints and went out on loan to Celtic, where his only appearance was in an Old Firm derby with Rangers in May 1999. Marshall ended up on the wrong end of a 3–0 scoreline, a game which saw Celtic's bitter rivals win the league at Celtic Park. This meant that Marshall had featured in just three league games in the 1998–99 season (two for Southampton and one for Celtic),
