Clark has won three senior Ireland caps but they were all in friendly games, against Wales, Uruguay and Greece.
That has led some to believe that the Aston Villa defender — who captained England at Under-20 level — could play for them again.
Clark, 23, said: “I was regular for England Under-17, Under-18s, at the start of my career, but it’s moved on now.
“I know there are a couple of friendly internationals leading up to the World Cup qualifiers and I’ve got to see what happens with that.
“Would I go back to England? No chance of that, not at all.”
