 After Attilio Demaría and Luis Monti, who both represented Argentina in 1930 and Italy in 1934, Ferenc Puskás (Hungary in 1954, then Spain), José Santamaría (Uruguay in 1954, then Spain) and José Altafini (Brazil in 1958, then Italy) became the third, fourth and fifth players to play for two national teams in the World Cup.In light of this, FIFA created stipulations describing that once a player represents a nation during a World Cup or its qualifying rounds the player cannot switch to another national team.Robert Prosinečki and Robert Jarni would later become the sixth and seventh such players, playing for Yugoslavia in 1990, then for Croatia in 1998; Davor Šuker was also selected in both squads, but did not play in 1990.
