Isidoro San José Pozo (born 27 October 1955) is a Spanish retired footballer.
During the 1973–74 season, at only 18, he made his first-team debuts, playing in two rounds of the Copa del Rey against Granada CF and UD Las Palmas but not being picked for the final because the juniors' coach, Manuel Sanchís Martínez, decided he should play, as captain, in the equivalent match of the category, the opponent also being FC Barcelona.
However, during a league game at Sporting de Gijón late into 1979, he suffered a meniscus injury which kept him out of the pitches for more than one year;[1] the situation was aggravated after the player, not fully recovered yet, was summoned for the cup final against Valencia CF.
[2] In his last two years, San José only appeared in 30 league matches combined, but still contributed to back-to-back UEFA Cups and the 1986 national championship – at that time, he had already lost his position to another youth graduate, Chendo.
He retired in June 1987 at nearly 32 after one season with RCD Mallorca, contributing relatively as the Balearic Islands side retained their top division status.
