Mulgrew began his career at Celtic, during which time he spent time on loan at Dundee United. He then played for Wolverhampton Wanderers, Southend United on loan and Aberdeen. He returned for a second spell with Celtic in 2010, spending six years at the club. In August 2016, Mulgrew left Celtic to join Blackburn Rovers. He played on loan for Wigan Athletic during the 2019–20 season, returning to Blackburn in January 2020, then spending the following season on loan at Fleetwood Town. He signed for Dundee United for a second time in June 2021. Mulgrew has made more than 40 international appearances for Scotland. Early life Mulgrew grew up in Kirkintilloch and attended Holy Family Trinity Primary School and St Ninian's High School in the East Dunbartonshire town. Club career Celtic Having progressed through Celtic's youth system alongside Aiden McGeady, Mulgrew turned professional in July 2002. Originally playing at centre back, he was soon encouraged to switch to left back due to the shortage of players in that position at the club. He won the Scottish Youth Cup with the club in 2004–05, beating St Mirren 2–0 at Hampden Park. Dundee United In order for him to gain competitive experience, in January 2006 Mulgrew was loaned out to fellow SPL side Dundee United for the remainder of the 2005–06 season. A successful spell at Tannadice saw him feature regularly, scoring twice (both free kicks) in 14 appearances and being named SPL Young Player of the Month for February. He then returned to Celtic hoping to force his way into first team contention, but was transferred to Wolverhampton Wanderers shortly thereafter without ever appearing for the Celtic first team. Wolverhampton Wanderers Mulgrew joined Wolves in part exchange for left back Lee Naylor on 23 August 2006. He made his debut for the club on 10 September in a 1–0 win at Leeds United. However, injury kept him out of most of the campaign and he was unable to force his way back into first team contention afterwards. Southend United Mulgrew was loaned out to English League One side Southend United at the end of the January transfer window for the remainder of the 2007–08 season, which saw the club lose in the play-offs to Doncaster Rovers.
