As in, the Irish team seems to include Northern Ireland, judging by Charlie's rundown of the World Cup results of the Home Nations. Amusing that Scotland lost to Luxembourg of all countries, while England's thrashing by Transsylvania proves that the magical countries don't necessarily correspond to the Muggle ones, or at least that Romania has several Quidditch teams just like Great Britain does. Of course Transsylvania does have one hell of a reputation in terms of the occult, so it makes sense in a way.
