Giovanni Trapattoni believes James McCarthy's decision to opt out of the Republic of Ireland Euro 2012 squad must be respected.
The 21-year-old Wigan midfielder would have been included in Giovanni Trapattoni's 23-man squad but opted out of the tournament as his father has been diagnosed with cancer.
He said: "Last week, he called me and told me what had happened with his family, and I told him, 'I am sorry, I am very, very sorry'.
"But he has decided to remain at home because he has a very heavy duty for his parents.
"I told him immediately that we would continue to follow him and that he will be in our plans for the future. He said, 'Thanks for this'."
Trapattoni revealed he had talked to McCarthy about the possibility of finding a way to still take him to the tournament, but admitted he was not ready psychologically to make the trip to Poland and Ukraine.
He said: "I spoke with him and he preferred to stay at home because he psychologically, he was not ready, he was afraid about this. I have to have respect about his choice.
"It's difficult to try to convince him - he is 21 years old. I tried, but he said he was sad, he was not confident about this situation.
"I have to have respect for this. I said 'Okay, you will be with us in the next campaign'."
McCarthy confirmed his decision in a statement which said: "I have made the very difficult decision to withdraw my name from selection from the Euro 2012 squad following the diagnosis of my father with cancer and an ongoing requirement for treatment.
"I have discussed this with the manager. He was very understanding and I thank him sincerely for that.
"I take this opportunity to re-affirm my complete commitment to playing for the Republic of Ireland.
"It is a huge honour and source of great pride for me and my family.
"Despite not being present, I would like to wish the manager and my team-mates every success at the tournament and hope that Irish fans can understand the reason for my decision at this difficult time."
