4. Roy Keane (Republic of Ireland)
Roy Keane’s departure from the Republic of Ireland’s training camp was one of the most memorable moments of the 2002 World Cup.
He was unhappy with the standard of Ireland’s preparations. And, it boiled over into an expletive-laden bust-up with boss Mick McCarthy in front of the squad at their base on the Pacific island of Saipan.
Instead of preparing to play the opener against Cameroon, Keane kept busy by walking around Cheshire with his dog Triggs.
