Biography
He arrived at AS Saint-Étienne, in 1972, replacing new coach Robert Herbin at fullback position. He was associated with Christian Lopez and had the habit to help the team offensively. He won many titles with AS Saint-Étienne. He was very popular at this time, and Bernard Sauvat wrote a song dedicated to him. Piazza earned 15 caps for Argentina, but could not participate to 1978 FIFA World Cup in his country due to family problems even though César Luis Menotti wanted him in the squad. In 1979, he played for Club Atlético Vélez Sársfield, before returning to France with Corbeil-Essonnes, as a player-coach but it was a failure.
