Roy Keane made a brutal dig at FAI executives as he spoke on ITV before the Ireland vs England game on Saturday.
Keane is famously no fan of how football is managed in Ireland, and his frustration at the FAI ultimately led to him falling out with Mick McCarthy and leaving the Ireland squad before the 2002 World Cup.
"There are a lot of good people at the FAI. But the people making the decisions probably couldn't organise a p*** up in a brewery, honestly," Keane said.
He also suggested Stephen Kenny's instance on playing possession-based football was a factor in his downfall as Ireland manager.
"Stephen Kenny wanted to play a certain brand of football, but we just didn't have enough quality players. We were playing too many passes, we were too open."
He added that Ireland had enjoyed the most success playing a more direct style of football.
It was an opening game to forget for new Ireland manager Heimir Hallgrimsson as the Boys in Green were outclassed by England, with former Ireland players Declan Rice and Jack Grealish scoring the goals in a 2-0 win.
On Tuesday, Ireland face Greece, where the Icelandic manager will be hoping for his first victory.
