Denis Irwin grew up in Cork and was educated at Coláiste Chríost Rí. As a schoolboy he excelled at both Gaelic football and hurling, and played at Croke Park more than once, on one occasion marking Niall Quinn.
In 12 years at Old Trafford, he made 296 Premier League appearances and won seven Premier League title medals, as well as three FA Cup winners medals (1994, 1996 and 1999), a League Cup winner's medal and Champions League and Cup Winners' Cup honours. He was comfortable in either of the full back positions and an expert at free kicks and penalties, and even in his mid thirties he was United's first choice left-back in preference to the much younger Phil Neville.
Irwin made his last appearance for Manchester United at Old Trafford against Charlton Athletic on the final day of the 2001-02 Premier League season (12 May 2002), which ended in a 0-0 draw. For his final game as a Manchester United player, Alex Ferguson awarded him the captain's armband.
Irwin joined Wolverhampton Wanderers on a free transfer in July 2002, coincidentally at the same time as his former Manchester United teammate Paul Ince made the move to the West Midlands club, having previously been at Middlesbrough.
After Wolves won promotion to the Premier League in 2003, Irwin was applauded by the Manchester United supporters when he walked onto the pitch at Old Trafford. Wolves were relegated at the end of the 2003-04 season, and the 38-year-old Irwin then announced his retirement.
