FAI chief executive John Delaney has described Roy Keane's outburst against Ireland as "sad" and urged the former Republic of Ireland captain to "move on".
On Friday, Ipswich manager Keane said he had little sympathy for the FAI's campaign to have their controversial World Cup play-off against France replayed following Thierry Henry's handball and said "what goes around comes around".
Keane's antipathy towards the FAI stems back to the Pacific island of Saipan seven years ago, when he left the team's pre-World Cup training camp, complaining that the facilities were sub-standard.
On Sunday, Delaney said that Keane should move on from the affair, telling Sky Sports News: "It's just a side-show.
"We've all moved on from Saipan - Niall Quinn, Mick McCarthy, the FAI and all the players - but it seems to me that he (Keane) hasn't.
"It's time for him now, in my opinion, to learn from the past - not live with it.
"I really thought the images shown around the world on Friday were very sad - it's sad to see a great former player reflected in the manner as he did."
