It was after considerable debate Carsley finally returned to the international scene 12 months ago following a three-year absence.
But despite the fact Ireland are virtually guaranteed to miss out on next summer's Euro 2008 finals, the 33-year-old Carsley has no intention of hanging up his Republic boots again.
"I'm just taking it game by game to be honest, but I enjoyed the game," said Carsley following a fine performance in the goalless qualifying draw with Germany at Dublin's Croke Park.
"I've always said if I'm playing well at Everton, then I don't see a reason why I can't continue.
"My old club mate David Weir is still playing for Scotland, and he is 37.
"I'm not saying I'm going to carry on to that age, but I feel good, so I'm going to keep going."
One of the reasons is Carsley can see the progress that has been made over the past year under manager Steve Staunton.
