Career
On 18 May 1980 he scored his first professional goal, netting the last in a 3–1 success at Getafe Deportivo for the Segunda División championship. In the 1984 summer, Zambrano signed for neighbouring Civil Defense Málaga in the top division, and scored his first goal in the competition on 30 March of the following year, the first in a 1–1 home draw against RCD Espanyol. His team was eventually relegated at the end of the season, and he moved to fellow league team Sevilla Football Club shortly after.
After two seasons appearing regularly with the Rojiblancos, Zambrano joined Celta de Vigo in 1987.
He retired with Real Murcia in 1992 at the age of 31, mainly due to injuries. Zambrano started working as a coach with amateurs Olont CF, and also had lower league spells at Ayamonte CF, Civil Defense San Fernando and AD Cartaya.
In 2007 he returned to his first club Recreativo, being appointed manager of the reserves. On 4 February 2008, Zambrano replaced fired Víctor Muñoz at the helm of the main squad.
After narrowly avoiding top flight relegation he renewed his contract with Recre on 23 May, but was sacked on 7 October.
