Career
Nicknamed "El Duende" ("the elf") due to his short height (he is 164 m tall), Pérez was a talented forward who played primarily on the left wing. He began his professional career with Comunicaciones in the late 1970s, and would go on to become one of the symbols of that club He also had stints with Municipal, Galcasa, Suchitepéquez, Once Lobos of El Salvador, Aurora Football Club, and Deportivo Jalapa.
In 1988 his services were required by the then Mexican top-flight club Leones Negros de la U. de G., where he played during the 1988-1989 season.
His team reached the final of the 1988-1989 domestic cup tournament, where he scored a goal against Toluca in the second leg, although U. de G. lost 2-3 on aggregate. A tough moment came during 1986 World Cup qualification when against Canada with the score 2-1 in favor of the Canadians, he missed a penalty kick, which would have equalized the score and given his team a good chance of advancing to the next round.
Instead, Canada advanced by finishing first of the group, two points ahead of Guatemala. He also managed Deportivo Heredia in the top flight (2008), Juventud Retalteca (2008), San Pedro (2010), and Sacachispas (2011).
