Egypt and Sudan had refused to play against Israel while Indonesia insisted on meeting Israel on neutral ground.
As a result Israel were proclaimed winners of their respective groups in the Asian/African zone. Fifa were understandably reluctant to allow a team to qualify for the World Cup finals without actually playing a match and so lots were drawn of all the second placed teams in the Uefa qualifying groups.
Wales were drawn out of the hat and awarded a two-legged play-off match against Israel with a place in Sweden for the winners.
In the days before Fifa used goal difference to separate teams level on points, play-off matches were arranged, and so Wales faced Hungary for a second time within the space of nine days for the right to face Brazil in the World Cup quarter finals.
