Born in Río Cuarto, Córdoba, Herrera started his youth career at local club Estudiantes de Río Cuarto before moving to Argentine giants Boca Juniors. Promoted to the first team in 1991, he was only an understudy to goalkeepers such as Carlos Navarro Montoya. In 1993, in a reserve match against Independiente, he was badly injured in a clash with an opponent, resulting in head trauma, a depressed cheekbone, orbital fracture and torn ligaments, sidelining him for nine months.
Atlanta, Toluca and Ferro Carril
Having played only once for the first team in a friendly match against San Lorenzo in 1995, Herrera decided to leave Boca Juniors and joined Club Atlético Atlanta, which played at the Primera B Nacional, the Argentinian second tier. There, he was the first-choice goalkeeper and played a total of 66 league matches.
In 1998, Herrera returned to Argentina joining Ferro Carril Oeste, but wanted to leave the club after just one year due to four months without payment.
On 15 July 1999, Herrera signed for Spanish club Deportivo Alavés for $1,2 million and a deal not to seek compensation for his unpaid wages. At the Basque club, he was an undisputed starter and won the Ricardo Zamora Trophy in his first season, conceding only 37 goals in 38 matches. His performances led the club to have the least conceaded goals in 1999–2000 La Liga and finishing 6h place, qualifying for the 2000–01 UEFA Cup.
Herrera remained a first choice for the following season, in which he was briefly suspended by Spanish FA for allegedly holding a false Italian passport, but later succeeded in proving his Italian origins. He helped Alavés to reach the 2001 UEFA Cup Final, where his team lost 5-4 during extra time after an own golden goal.
During the 2001–02 season, Herrera was no longer and undisputed starter at Alavés in which proved to be his last season at the club.
In May 2002, Herrera joined Fulham on a three-year contract. A backup to Edwin van der Sar and Maik Taylor, he only made his Premier League debut on 24 February 2003 in a 1–1 draw against Tottenham Hotspur as a substitute after Taylor was sent off. His second and last appearance was a 2–2 draw against Southampton, in which Herrera played the whole match.
Estudiantes de La Plata
Herrera joined Estudiantes on loan in 2003 and was signed after his loan and contract with Fulham. Previously a starter, he lost his spot to Mariano Andújar after being sent off in a 2–0 loss against Boca Juniors in 2006, never being selected again by then manager Diego Simeone before resigning his contract in October 2006. Nonetheless, he was part of the squad that won the 2006 Apertura championship, defeating former side Boca Juniors in an end-of-season title deciding playoff.
