Career
Sconfianza began his playing career with Argentine first division club San Lorenzo de Almagro. He made his professional debut against Independiente on 4 August 1963, and would make 109 league appearances for the club during a seven-year stay. While playing for San Lorenzo in a friendly tournament in Spain, representatives of Real Madrid observed Sconfianza, but never made an official approach for his services.
One season later, he joined Puebla F.C. for four seasons, making 27 league appearances during the 1975-1976 season.
Sconfianza was part of the Argentina squad at the 1964 Summer Olympics in Tokyo, but did not appear in any matches.
