Juan José Díaz Galiana

Juan José "Juanjo" Díaz Galiana (8 January 1949 – 6 December 2017), sometimes known simply as Juanjo, was a Spanish football manager.

Career RCD Espanyol appointed the little-known Diaz to replace Benito Joanet in January 1990. Diaz would lead Espanyol to the 1989–90 Segunda División play-offs, where the club won promotion following a victory over CD Málaga. He left the club immediately after the play-offs.

In June 2001 Juanjo was named as manager of second-division side CD Badajoz. That October, however, he was relieved of his duties after winning only two points out of a possible 27.

He died in Terrassa, Catalonia, at the age of 68, following a long illness.
