Former Ireland midfielder Carsley made it clear that he would not be participating in the pre-game singing activities.
After the 2-0 win, he said: "I think like I said in my first press conference, today is an immensely proud position for myself and for my family.
"I've got so much respect for both national anthems. I'll stand there proud today and like I say, it's a really proud moment and I can't wait for the game. I'm not sure (if it's unfair) to be honest, everyone is entitled to their opinion.
"As a player making my debut in 96 or 97, I was totally focused on the game. It was something I found difficult to get used to in terms of the delay. So I used that time to concentrate and keeping my focus and it hasn’t changed since I started coaching."
