Unhappy McCarthy says he can "walk away" from Irish job

Republic of Ireland coach Mick McCarthy says the week-long controversy over the sacking of captain Roy Keane has sapped his strength to continue in the job.

"I will walk way with my head held high," McCarthy said today.

"It's been the worst week of my entire life - I regret Roy not being in my team but I have no regrets about anything else.

"I have handled the situation the way I have. I have made mistakes in my career and I will make them again in the future. I can't affect what people think about me but I have certainly learnt a lot.

"There is always some incident in a World Cup which causes a huge media interest and unfortunately for us it has been in the Republic of Ireland camp this time. Hopefully now we can move on now, play the games and play well, and discuss football."

Ireland face Cameroon in their opening game at the finals this weekend with McCarthy set to quit after attempts to bring Keane back into his squad.

McCarthy wanted a "sincere apology" from Keane after the Manchester United midfield star verbally abused the coach in front of the rest of the squad last week and was sent home to England.

But Keane told Irish broadcasters RTE last night:

"I do not consider that the best interests of Irish football will be served by my returning to the World Cup. The damage has been done."

"In the interests of all genuine supporters of Irish football the time has now arrived when I should bring a conclusion to the continuing speculation with regard to my participation in the World Cup and for the players to concentrate fully on their preparations for the competition free from all further distractions.

"Whilst I appreciate all the support which I have received I do not consider that the best interests of Irish football will be served by my returning to the World Cup.

"The damage has been done. I wish the team and the management all the best.

"They have my full support throughout the competition and I urge all the people of Ireland to give their support to the team and I do not feel that any useful purpose will be served by my making any further comment."

Senior players wanted keane to return to the squad but the midfielder refused to apologise and McCarthy feels undermined despite his stand against the poor discipline of the United star.
