† Appearances (Goals).
Most of his professional career was spent in Portugal, amassing Primeira Liga totals of 288 games and 59 goals over the course of 13 seasons mainly in representation of Boavista and Benfica. Retiring in 2005, he subsequently became a coach.
Born in Santa Cruz de la Sierra, Sánchez started his career at hometown's Club Destroyers, then moved to Club Bolívar. He became the first Bolivian to play professionally in Europe, when he was signed by Sport Lisboa e Benfica for the 1990–91 season, but was not very successful there, also being loaned to Lisbon neighbours G.D. Estoril Praia.
Released in 1992, Sánchez signed with Boavista Futebol Clube, eventually becoming one of the team's best players. This prompted a 1997 return to Benfica, but the player again failed to settle, returning to the Axadrezados (chequereds) and being crucial to the club's only league conquest in 2001, with nine goals in 33 games.
After a serious anterior cruciate ligament injury, Sánchez eventually lost importance in Boavista and left the club in 2004 after a coaching spell, returning home for a final season with Oriente Petrolero and retiring as a player at the age of 36. In his last appearance, on 14 March 2005 against Club Blooming, he assaulted referee Wilson Aliaga, being suspended for 18 months.
Sánchez was a leading player for Bolivia, being crucial to the nation's qualification for the 1994 FIFA World Cup. Bolivia exited the competition in the group stage, and he scored the nation's only goal of the tournament in a 1–3 loss against Spain; this was also Bolivia's first and only goal in three appearances in World Cup tournaments.
Sánchez appeared in a total of 57 international matches over 16 years, scoring 15 goals. In 2006 he was named national team manager, being sacked after the unsuccessful 2010 World Cup qualification campaign.
