Born in Badalona, Barcelona, Catalonia, Aguado began his career at local CE Sabadell FC (in the second division). After two seasons, he joined Real Zaragoza in La Liga for 1990–91, quickly establishing as first-choice whilst displaying aerial ability and team leadership alike (he would be early on named club captain).
Aguado was part of the Zaragoza team that beat Arsenal in the 1994–95 UEFA Cup Winners' Cup final. From 1997–99 he scored an impressive nine league goals combined, including a brace in a 2–2 home draw against SD Compostela on 28 September 1997. However, during his 13-year career at the Aragonese, he also amassed a poor disciplinary record, collecting, in the league alone, 109 yellow cards and being sent off 18 times, the latter being an all-time worst in the competition.
After Zaragoza's top flight relegation in 2001–02, Aguado retired from professional football (he was still with the squad during the following season, but made no appearances whatsoever) after 473 official games with the same team.
