Which makes me wonder why he did the interview - was he trying to repair his image?
Keane and McCarthy have not exactly seen eye to eye for about eight years - but the midfielder has managed to keep a lid on his feelings for all this time.
The whole thing is daft, absolutely daft.
The Republic lose their best player and Keane misses the World Cup.
Blown his chance
World Cups come around every four years and Keane will probably not get another chance.
He may have had a point about the facilities, travel arrangements, pitches etc - but so would every other Republic of Ireland player in the last 25 years.
The Football Association of Ireland (FAI) is not the most efficiently run organisation in the world - but let's not forget they administer a part-time league.
We've all had it - Aldridge, Houghton, Whelan, O'Leary, Moran and numerous others.
McCarthy has been banging his head against the wall about the FAI for years but he hasn't been able to change it - and Jack Charlton was unable to do so either.
What it should never do is stop you from playing for the Republic.
Let me say at the start that I do not condone Roy Keane's abusive and personal attack on Mick McCarthy.
Every right-minded person would agree that he was out of order.
But knowing that Keane was livid about poor training facilities, why did the manager invite his captain to explain himself in front of the rest of the squad and staff?
The situation should have been handled in private.
