Giovanni Trapattoni is longer the manager of the Republic of Ireland football team.
The Italian and his assistant Marco Tardelli have parted company with the FAI by “mutual consent”.
In a press statement, the Association said the decision was taken after an “amicable meeting” this morning.
Giovanni 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.
FAI chief executive John Delaney said: “We thank Giovanni Trapattoni, Marco Tardelli and Franco 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 playoff in France.
“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 Board of the FAI will meet in due course to discuss the process in relation to the appointment of a new manager.”
