Because of the increasing number of invitations to play matches and international tournaments, the Asociación Paraguaya de Fútbol decided to officially create the national team and select the striped red and white jerseys that until this date remain as the official colours (taken from the Paraguayan flag). In late 1919, Paraguay accepted the invitation to play the 1921 Copa América and in order to prepare for that occasion a number of friendly matches were played between 1919 and the start of the tournament in 1921. The first of those friendly matches was a 5–1 loss against Argentina, and it marked the first international game by the Paraguayan national football team. When the 1921 Copa América finally arrived, Paraguay surprised everybody by beating then three-time South American champions Uruguay by 2–1, being this the first match in an official competition for the Paraguayan football team. Paraguay eventually finished fourth in the tournament and became a regular participant of the tournament for the next editions.
