Plaza managed
Real Jaén in a record 229 games in the 1990s, in Segunda División B. He also led
Córdoba in
1992–93. In
1996–97, he left halfway through a promotion-winning season to join
Málaga, but was fired after 13 games of the following campaign with the team in 7th place, with three points less than leaders
Granada; the season ended with promotion under his successor
Ismael Díaz.
Elche appointed Plaza in 1998 and he led the team to promotion to the Segunda División via the
playoffs. He was sacked in January 2000 with the team in the relegation zone. ==Personal life==
