The former Hamilton Academicals midfielder has reiterated his support of the veteran Italian coach and believes that he has achieved 'so much' for Irish football
Trapattoni has come under severe criticism for his recent guidance of the Irish international team, which has seen them slide from 18 to 36 in the latest Fifa rankings.
Speaking to RTÉ ahead of the friendly game against Greece which will take place on Wednesday November 14, McCarthy said that the Italian coach had nevertheless 'achieved so much' and that his man management skills helped the players raise their game following the 1-6 home defeat against Germany in October.
"I think he's the right man," the 22-year-old told reporters. "He has achieved so much for Ireland. The result against Germany wasn't acceptable, but I think he will kick us on again. He got us all up for the Faroe Islands game and hopefully we can get back to back wins now."
The Latics midfielder has recently found himself in the starting line up of the Boys in Green team, in part owing to injuries sustained by Glenn Whelan and Keith Andrews, and he believes that the Ireland boss will integrate new players 'gradually'.
"He will blend the kids in gradually," he said. "He won't just throw everyone in. He can't. That's not the right thing to do," concluded McCarthy.
