Ireland manager Giovanni Trapattoni and assistant Marco Tardelli have had their contracts with the Football Association of Ireland ended by mutual consent.
The Italian duo’s departure came after what the FAI described as an “amicable” meeting this morning.
Ireland suffered their second successive defeat in Vienna last night.
“I want to thank everyone in Ireland who has given us their support during our time here which has always meant a lot to us,” Trapattoni said :
"We leave this country with emotion because we understand the Irish supporters who have a well-deserved international reputation and they have our utmost respect."
"I would also thank all FAI staff members, including the backroom team and the players, who have been great to work with during the last three campaigns.
"I wish them well in the future and hope that the job we have done leaves everything in a good place for my successor to take over."
Delaney acknowledged that the current World Cup qualifying campaign had been unsatisfactory, but highlighted the earlier achievements of the veteran Italian manager.
“We thank Giovanni Trapattoni, Marco Tardelli and Fausto Rossi for the last five and a half years during which we qualified for our first major tournament in ten years and were close to qualification for 2010 World Cup in South Africa after the play-off in France,” the FAI supremo said.
“This particular World Cup campaign has been disappointing, but Giovanni leaves us with a group of good young players which should form the basis of the squad that the new manager will use for the European Championships in France 2016 when 24 teams qualify.”
The FAI acted quickly in the aftermath of the defeat in Vienna, cancelling a scheduled Trapattoni news conference in Dublin this afternoon and the board says it will meet in due course to consider a replacement.
