Atletico Madrid's first football team is writing an exceptional chapter in the long history of World Cup finals, during the final showdown between Spain and Argentina on Sunday, as the squads of both finalists include nine players from the capital's giant, a number that has only been seen three times in the history of World Cup finals, the last being 76 years ago. Argentina coach Lionel Scaloni had called up six Atletico Madrid players to his squad on May 28, ahead of the finals, while Spain coach Luis de la Fuente named three Atletico players in his squad, announced on May 25. The number of Atletico Madrid players in both the Spanish and Argentine squads remained as is after the official summer transfer window moves so far, as Argentine Nicolas Gonzalez returned to Juventus on July 1 after his loan ended, reducing the number of Atletico players in the Argentine squad to five, but Diego Simeone's team completed the same day the signing of Spanish Alejandro Grimaldo from Leverkusen, raising the number of Atletico players in the Spanish squad to nine. This number puts Atletico Madrid second in the list of clubs that have contributed the most players to national teams in World Cup finals throughout history, with Slavia Prague topping this statistic, having 12 players from its ranks in the 1934 final between Czechoslovakia and Italy. Atletico Madrid shares second place with Italy's Juventus and Uruguay's Penarol, as the former provided Italy with nine players in the 1934 final, while nine Penarol players were in the Uruguay squad that beat Brazil in the 1950 'Maracana' final, although that match was technically not a final as the final round was played as a group stage, but the Uruguay-Brazil match was the last and decisive one between the two teams involved in the title race. It is worth noting that Sunday's final will feature eight players from Barcelona, all in the Spanish squad, placing the Catalan club fifth in the ranking of clubs with most players in a final match, tied with Brazil's Vasco da Gama (1950), Hungary's Budapest Honved (1954), Italy's Juventus (2006), and Barcelona itself in 2010.
