When called up for his first game at the international level, an under-21s match against Turkey in 1991, Keane took an immediate dislike to the organisation and preparation surrounding the Irish team, later describing the set-up as "a bit of a joke". He would continue to hold this view throughout the remainder of his time spent with the national team, which led to numerous confrontations with the Irish management. Keane declared his unavailability to travel with the Irish squad to Algeria, but was surprised when manager Jack Charlton told him that he would never play for Ireland again if he refused to join up with his compatriots. Despite this threat, Keane chose to stay at home on the insistence of Nottingham Forest manager Brian Clough, and was pleased when a year later he was called up to the Irish squad for a friendly at Lansdowne Road. After more appearances, he grew to disapprove of Charlton's style of football, which relied less on the players' skill and more on continuous pressing and direct play. Tensions between the two men peaked during a pre-season tournament in the United States when Charlton berated Keane for returning home late after a drinking session with Steve Staunton.
