In an eighteen-year playing career for Cobh Ramblers, Nottingham Forest (under Brian Clough), Manchester United (under Sir Alex Ferguson) and Celtic, Roy Keane dominated every midfield he led to glory. Aggressive and highly competitive, his attitude helped him to excel as captain of Manchester United from 1997 until his departure in 2005. Playing at an international level for nearly all his career, he represented the Republic of Ireland for over fourteen years, mainly as team captain, until an incident with national coach Mick McCarthy resulted in Keane’s walk-out from the 2002 World Cup.
