After 27 years, Brazil organized the Copa América again and won the tournament. Champions in 1919 and 1922, also playing at home, the Brazilians put on a historic spectacle, breaking several records. With matches being held in four cities (Rio de Janeiro, São Paulo, Santos and Belo Horizonte), the 21st edition of the Copa boasted eight national squads. Just Argentina gave up participating, since their national competition was entering its final straight. Nevertheless, despite the absence of the Argentineans, three-time Cup champions, the tournament was a huge success.
After 29 games (the greatest number until then), the competition reached a record of 135 goals scored. The majority claimed by the Brazilian team, who bagged 46 goals in 8 matches, another historic achievement. After winning their five opening matches in convincing style (9-1 against Ecuador; 10-1 against Bolivia; 5-nil against Chile; 7-1 against Peru and 5-1 against Uruguay), the side managed by Flávio Costa lost unexpectedly to Paraguay 2-1 in the last and decisive match. This result brought on an extra match, during which the Brazilians didn’t hesitate. Quite the contrary, the team led by strikers Ademir, Tesourinha, Zizinho and Jair Rosa Pinto thrashed the Paraguayans 7 to nothing, the highest score in a title match. Prolific striker Jair, with 9 goals in the competition, became the greatest top scorer in a single edition of the Cup.
The edition with less participating teams was held in 1925, counting only three countries: Argentina, Brazil, and Paraguay. The format adopted at that time consisted of matches between the teams in inning and re inning. Argentina won the championship.
