Trophée Zamora
On 8 July 1999, Herrera moved to the Spanish La Liga after signing a three-year contract with Deportivo Alavés for 200 million pesetas. 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.
