1. Roy Keane vs Mick McCarthy and the FAI
During the build up to the 2002 World Cup, Keane had been growing increasingly frustrated over the Football Association of Ireland’s (FAI) preparation for the tournament. No balls or bibs, pitches with too much sand and not enough water were all at the top of Keane’s grind list, and tensions boiled over one night in Saipan when McCarthy called a clear the air meeting with his players.
Keane felt as though he was being singled out and exploded, telling McCarthy to “stick the World Cup up your b******,” before being sent home to miss out on the showpiece event.
