Born in Río Cuarto, Córdoba, Herrera started his career with Argentine giants Boca Juniors in 1991, but he signed for Club Atlético Atlanta of the third division three years later after failing to make an impact. There, he helped to the 1995 championship as the club achieved promotion to the second level.
In 1998, Herrera moved to Mexico to play for Deportivo Toluca FC, but he soon returned to his country where he represented Ferro Carril Oeste during two seasons. The following year he signed with Spain's Deportivo Alavés, being an undisputed starter in two of his three campaigns at the Basques and only missing two La Liga games out of 76; in his first year he was awarded the Ricardo Zamora Trophy, with only 37 goals conceded (all 38 matches played).
On 16 May 2001, Herrera was in goal during the 4–5 extra time loss against Liverpool in the season's UEFA Cup final. In 2002, no longer an automatic first-choice with Alavés, he was signed by Premier League team Fulham on a three-year contract, but he only made two appearances before being loaned to Estudiantes de La Plata and eventually released.
In 2006, Herrera saw Estudiantes win the 2006 Apertura championship, defeating former side Boca Juniors in an end-of-season title deciding playoff. He subsequently retired from football, at the age of 37.
