† Appearances (Goals).
He amassed La Liga totals of 94 games and 19 goals over the course of six seasons, appearing in the competition for Real Madrid, Espanyol, Valladolid and Racing Santander. He added 170/55 in Segunda División.
Born in Madrid, Aganzo was a product of Real Madrid's youth system, and made his debut with the first team on 20 February 2000, in a 1–1 away draw against Valencia CF. Never a part of the club's plans, he went on to serve four consecutive loans: CF Extremadura, RCD Espanyol, Real Valladolid and Levante UD; however, after appearing against Rosenborg BK in the 1999–2000 UEFA Champions League, he earned a winner's medal.
After moving to Deportivo Alavés for the 2007–08 campaign, contributing with ten goals to help the Basque side narrowly avoid second division relegation, Aganzo was released at the end of the season, joining another team in that level, freshly promoted Rayo Vallecano, on a free transfer. He scored a career-best 12 goals in his first year as the team easily retained its newfound league status, being regularly used during three years and leaving the club in July 2011, aged 30.
