#2 Ryan Giggs
The current Wales manager is a true legend at United as he holds several records to his name. Giggs was an active player for United from 1987 to 2014 when he retired. In that period, he managed a record 963 appearances in all competitions for the Red Devils.
His raw speed and gifted left foot created special memories for United fans. Since making his senior debut in 1990, he scored at least a goal in 23 out of 24 seasons that followed.
Giggs won a whopping 34 trophies with United to make him the most decorated player in the club's history. He was part of the team that lifted the treble in 1999 and UEFA Champions League trophy in 2008.
He scored a total of 168 goals in all competitions for the club. The Welshman is ranked seventh in United's all-time scorer's list tied with Joe Spence but he has made more appearances.
He famously took the role of player/coach in 2014 for United's last four matches of the 2013-2014 season following David Moyes' sacking. At one point, he even substituted himself in at halftime of a match. He was later appointed as assistant manager to Louis Van Gaal in the two seasons that followed.
