The Irishman made 529 appearances for the Reds between 1990 and 2002, placing him ninth on our all-time list.
A mainstay at left-back, Denis could also play on the right-hand side and was a key member of the side which stormed to seven of the first nine Premier League titles.
Irwin played in 62 games in all competitions as United romped to a first-ever Double in 1993/94, and that side comes together to form a solid spine in our XI of his most common team-mates during his club and international career, picked by position.
Peter Schmeichel played with Irwin 314 times and is therefore unopposed in goal, while Denis was aided in his early days at United by the formidable pairing of Gary Pallister and Steve Bruce at centre-back.
