Álvaro 'Aldo' Pedro Duscher (born 22 March 1979) is an Argentine football manager and former player who played as a defensive midfielder.
Renowned for his physical presence on the pitch, Duscher also held an Austrian passport, and spent most of his professional career in Spain, playing in 338 official matches for four clubs – most notably at Deportivo.
After just five La Liga appearances in his first year he featured more in the following years, as a complement and future replacement to veteran Brazilian Mauro Silva; on 10 April 2002, his tackle led to a breakage in David Beckham's metatarsal in a UEFA Champions League game against Manchester United, which almost cost the English player his presence in the FIFA World Cup.
