Martín Herrera

Journeyman Subsequently, Herrera joined Club Atlético Atlanta of the Primera B Metropolitana. He then had brief spells with Deportivo Toluca FC (Mexico) and Ferro Carril Oeste, leaving the latter after not being paid for several months. He was an undisputed starter in his first year, being awarded the Ricardo Zamora Trophy with only 37 goals conceded (all 38 matches played), which was good enough to qualify to the UEFA Cup after the sixth-place finish.

Herrera continued to be first choice for the Basques in the following season, but was also briefly suspended by the Royal Spanish Football Federation for allegedly holding a false Italian passport. He later succeeded in proving his origins, and helped his team reach the final of the UEFA Cup on 16 May 2001, a 5–4 extra time loss against Liverpool after an own golden goal.

Fulham In May 2002, Herrera agreed to a three-year deal at Fulham. 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 away draw to Tottenham Hotspur as a substitute, after Taylor was sent off.

Herrera's second and final competitive appearance took place on 16 March 2003, when he started in the 2–2 draw against Southampton at Craven Cottage.

Estudiantes LP Herrera returned to his country and its Primera División on 17 July 2003, being loaned to Estudiantes de La Plata. Initially a starter, he lost his spot to Mariano Andújar after being sent off in a 0–2 loss at Boca Juniors in September 2006, never being selected again by manager Diego Simeone before terminating his contract the following month; nonetheless, he was part of the squad that won that year's Apertura championship, defeating the same opposition in the championship playoff.

Estudiantes RC After one year out of football, the 37-year-old Herrera returned to activity with his first club Estudiantes Río Cuarto. He retired in 2009.
