Moore missed the return game against Spain due to injury, but then won his second FAI XI cap against the Netherlands on 5 May 1932. He scored the FAI XI's second goal in a 2–0 victory. Moore shot from twenty yards and bought the 30,000 crowd to their feet. However the highlight of Moore's international career came on 25 February 1934 at Dalymount Park when the FAI XI made their World Cup debut in a qualifier against Belgium. He scored all four goals for the FAI XI as they came from 2–0, 3–1 and then 4–3 down to draw 4–4. As a result, Moore became the first player ever to score four goals in a World Cup game. Two months later in another qualifier on 8 April 1934, Moore scored his seventh and last goal for the FAI XI in a 5–2 defeat against the Netherlands.
