These are the squads of the 1980 Mundialito tournament that was played between 30 December 1980 and 10 January 1981, in Uruguay. Only six teams participated, because only six countries had won the FIFA World Cup at the time, including Argentina, Brazil, England, Germany, Italy, and Uruguay. The Netherlands, the runner-up at the 1974 and 1978 World Cups, were invited in place of England, who declined.
