In January 1997, aged almost 31, Montoya joined CF Extremadura in La Liga, suffering relegation with that and his following two teams, CP Mérida and CD Tenerife, also in the first division. After a brief spell in Chile with Club Deportes Concepción, he returned to Argentina and played top-flight football for Chacarita Juniors, Club Atlético Independiente (after the promotion of youngster Óscar Ustari, the 39-year-old did not see his contract renewed) and Club de Gimnasia y Esgrima La Plata, during five seasons combined.
