Roy Maurice Keane (born 10 August 1971) is an Irish football manager and former professional player. He is the joint-most successful Irish footballer of all time, having won 19 major trophies, 17 of which came at Manchester United, in his club career. He served as the assistant manager of the Republic of Ireland national team from 2013 until 2018.
In his 18-year playing career, Keane played for Cobh Ramblers, Nottingham Forest and Manchester United, before ending his career at Celtic. Keane was a dominating box-to-box midfielder, noted for his aggressive and highly competitive style of play, an attitude that helped him excel as captain of Manchester United from 1997 until his departure in 2005. Keane helped United achieve a sustained period of success during his 12 years at the club. He then signed for Celtic, but retired as a player less than a year later.
Keane played at international level for the Republic of Ireland over a period of 14 years, most of which he spent as captain. At the 1994 FIFA World Cup, he played in every Republic of Ireland game. He was sent home from the 2002 World Cup after a dispute with national coach Mick McCarthy over the team's training facilities.
