Joseph Denis Irwin (born 31 October 1965) is an Irish former professional footballer and sports television presenter.
As a player, he played as a full-back from 1983 to 2004. Irwin is best known for his long and successful stint at Manchester United, where he established himself as one of the most important players in the United team that won a host of domestic and European trophies in his time there between 1990 and 2002. He has been regarded by Alex Ferguson as, pound for pound, his greatest ever signing.
Earlier in his career he played for Leeds United and then Oldham Athletic, and finished his career with a two-year spell at Wolverhampton Wanderers, the club he supported as a child.
