Republic of Ireland manager Martin O'Neill has hit back at Ronald Koeman in the row over James McCarthy and in a statement realeased tonight, called the Everton boss a "master tactician of the blame game".
Koeman arrived to his weekly press conference this afternoon with a prepared statement in which he claimed that the Ireland medical team assessed that it would be "high risk for James to play against Wales".
The Everton boss was angered by the fact that the Irish midfielder had been selected to start in the World Cup qualifier against the Welsh last week, a match he did not feature in after aggravating his hamstring in the warm-up.
Koeman went on to accuse the Irish boss of "not protecting the player" by selecting him, after McCarthy himself said he was fit.
“Clearly James was not fit to play. He had trained for only two days with Ireland and he broke down during the warm up", Koeman continued.
“He has played only one game from the start in 2017. He did not play for three weeks before the Wales game."
But O'Neill has turned the tables on the Dutchman in his statement by highlighting the amount of games McCarthy played in pre-season after returning from international duty at Euro 2016.
"Once again the Everton manager, master tactician of the blame game, has struck out in his comments today, criticising both myself and James McCarthy", O'Neill begins.
"Perhaps a review of Everton's pre-season programme might provide some enlightenment.
"James had a magnificent tournament for the Republic of Ireland last summer during UEFA EURO 2016, playing his last game in very late June.
"He then returned to Everton after a very short break, but only 11 days later, he played his first of three games, all within an eight-day period, against Real Betis, Manchester United and Espanyol. Overloading?"
O'Neill was also keen to point out the fact that the player has spent very little time in the Irish camp over the last number of months.
"It should be added that James last played for his country on the October 9, 2016 - almost half a year ago. Since that time he has been totally under Everton's supervision.
"James is diligent and conscientious in his professional preparation. Perhaps, in this instance, quiet introspection may serve the Everton manager and his medical staff better."
The club versus country row really flared up last September when both sides clashed over McCarthy's possible participation in the September qualifier against Serbia.
The 26-year-old did not feature in Belgrade in the end, due to a groin strain, but the situation intensified when he played against Georgia and Moldova last October having not yet featured for Everton before the double header.
And right now it does not look like either side is willing to back down.
