When Ryan began his international career in 1949 there were, in effect, two Ireland teams, chosen by two rival associations. Both associations, the Northern Ireland – based
IFA and the Ireland – based
FAI claimed jurisdiction over the whole of Ireland and selected players from the whole island. As a result, several notable Irish players from this era, including Ryan, played for both teams.
FAI XI Between 1949 and 1955 Ryan made 16 appearances and scored 3 goals for the
FAI XI. He made his debut in a 3–1 defeat to
Sweden on 13 November 1949 in a qualifier for the
1950 World Cup. He scored his first two goals for the FAI XI in October 1953 during the qualifiers for the
1954 World Cup, one against
France in a 5–3 defeat and the second, a penalty, against
Luxembourg in 4–0 win. On 7 November 1954 in a friendly against
Norway, he scored his third goal, again from the penalty spot, and earned the FAI XI a 2–1 victory. He made his last appearance for the FAI XI on 27 November 1955 in a 2–2 draw with
Spain.
IFA XI Ryan made his one and only appearance for the
IFA XI in a 0–0 draw with
Wales on 8 March 1950. As well as being part of the
1950 British Home Championship, the game also doubled up as a qualifier for the
1950 World Cup. Ryan, together with
Con Martin,
Davy Walsh and
Tom Aherne, was one of four players born in the Irish Free State, included in the IFA XI that day. Ryan had earlier played for the FAI XI in the same competition, and as a result had played for two different teams in the same
FIFA World Cup tournament. This situation eventually led to intervention by
FIFA and as a result Ryan became one of the last four
Irish Free State – born players to play for the IFA XI. ==Later years==
