Republic of Ireland manager Mick McCarthy has launched a bitter attack against Roy Keane after sending his captain home from the World Cup.
Reports on Thursday evening suggested that Manchester United were set to charter a private jet to Saipan to bring Keane back home to England.
Explaining his actions, McCarthy branded Keane a "disruptive influence" and said the midfielder showed "an utter disregard and disrespect" for him.
The Football Association of Ireland has fully backed the decision to send Keane home, after the Manchester United star publicly complained about training facilities on the Pacific island of Saipan.
McCarthy said he called a team meeting on Thursday to clear the air, but that it had turned into a "slanging match".
"I asked anybody to air any grievances among the players or staff," he revealed.
"I cannot and will not tolerate being spoken to with that level of abuse being thrown at me so I sent him home."
In a news conference held later on Thursday in Dublin, the FAI backed McCarthy's decision and defended the facilities in Saipan.
"We view the events with great regret but the manager is fully supported by the association," said FAI treasurer John Delaney.
"The wellbeing of the squad is our interest and now we must put this unfortunate affair behind us and get on with the job as best we can.
"We believe the Association provided the best facilities."
McCarthy added he had become increasingly irritated at having to field press inquiries about comments made by Keane, who had maintained his "sanity is more important" than staying with the squad.
"There has been an uneasy feeling around the place for a few days," he said.
"I was asked about remarks he made in a newspaper article and I don't want to be doing that throughout the whole World Cup because doing tit-for-tat in the media is not my way.
"We all know his ability but when he makes a public and open show of his
opinions and makes such public criticisms everybody starts talking about it.
"He is one of the best players in the world but he is a disruptive influence."
Former Republic of Ireland manager Jack Charlton backed McCarthy's stance, adding that Keane's behaviour would incur the anger of the fans.
"Roy's made a mistake and has got to live with the consequences. He's got to face the anger of the fans, " he said.
"I have to back Mick in that situation. I don't understand why Roy has done this.
"Mick will have his reasons for what has happened and you can't have players
dictating what happens just days before the tournament starts."
McCarthy, who was flanked at the news conference by new captain Steve Staunton along with Alan Kelly and Niall Quinn, added that no-one else in the squad had complained about the conditions.
"You don't see too many complaints from anyone else here. But sometimes Roy sees the world through his eyes only," he said.
"I did it with the best interests of the team at heart when I said he should go home.
"This is a weight off my mind. I came here to enjoy the World Cup and I was stopping enjoying it. But from tomorrow I am going to start enjoying it again.
"This is a huge decision but I am happy to go to the World Cup one man down rather than with a man who shows utter disregard and disrespect for me."
Irish national broadcaster RTE reported on Thursday evening that Manchester United were set to charter a private jet to Saipan to transport Keane back to England.
