Luis Diego López Breijo (Latin American Spanish: [lwisˈðjeɣo ˈlopes];[a] born 22 August 1974) is a Uruguayan football manager and former player who played as a defender.

Two years later he signed with Racing de Santander in Spain, playing 39 La Liga games in his debut season but receiving nine yellow cards and three red in the process;[2][3][4] in Cantabria, he shared teams with compatriots Fernando Correa and José Zalazar.

[6] On 14 April 2009, following a tunnel brawl with ACF Fiorentina's Felipe Melo in a 2–1 away loss, both López and the Brazilian received a five-match ban.

On 9 September 2010, after not being called up to Cagliari's 2010–11 pre-season camp,[9] López announced his retirement from professional football, having appeared in 344 official matches for his main club.

[6][10] López made his debut for Uruguay on 19 October 1994, in a friendly match with Peru in the Estadio Nacional José Díaz in Lima (1–0 win).

[11] The following year he represented the nation at the Copa América, with the tournament being held on home soil and won by the hosts, who conceded just four goals in six matches.

In July 2012, López was named at the helm of the Primavera under-19 side of Cagliari and, on 2 October, was unveiled as new assistant coach for the main squad after the Ivo Pulga-led club parted ways with Massimo Ficcadenti.
