During a 10-year spell at Arsenal, Marshall was part of the squad which won the Premier League and FA Cup double in 1998, in addition to the league title in 1991, and the FA Cup and League Cup in 1993.
In 1996 he was named Arsenal's young player of the year.
The Scottish defender made his senior debut in 1993 against Sheffield Wednesday, just nine days before the FA Cup final against the same team at Wembley.
He was unable to force his way past the likes of Tony Adams and Martin Keown into the Gunners' first team on a regular basis and joined Southampton in 1998.
He made the step into coaching at Wycombe Wanderers, having also played at Celtic and Sheffield United during a 13-year career.
Marshall joined Wycombe's Academy coaching staff under Gary Smith and it was at Adams Park that he met Lambert, who managed Wycombe from 2006 to 2008.
Having moved to former club Brentford to manage the U18 team in 2007, he joined Chelsea's Academy staff in 2008.
Spells with QPR and the Arsenal Soccer School in Oman followed before he was appointed Professional Development Coach at Norwich City in 2012, in charge of the club's Under-21 team.
