Washington Sebastián Abreu Gallo (Spanish pronunciation: [seβasˈtjan aˈβɾew]; born 17 October 1976), nicknamed El Loco (The Madman), is a Uruguayan football manager and former striker.

[8] A Uruguayan international for more than 15 years, Abreu represented his country in two World Cups and three Copa América tournaments, winning the latter in 2011.

Born in Minas, Lavalleja Department,[1] Abreu played in numerous clubs throughout the Americas (Uruguay, Argentina, Mexico and Brazil).

In early January 2009, Abreu returned to Spain after a ten-year absence, being loaned by River to Segunda División side Real Sociedad, which had lost habitual first choice Iñigo Díaz de Cerio for the season due to a serious leg injury.

[17] In July, he had his link extended until 31 December 2012 with a release clause of US$11.3 million, with the player declaring he had previously held talks with Universidad de Chile and Trabzonspor of Turkey.

[28] In late December of the same year, he joined Chilean Primera División's Audax Italiano from Puerto Montt, in the same country but one level below; this transfer broke a world record, as it marked him as the first player to have played for 26 professional clubs.

[37] Abreu's hometown side Olimpia de Minas announced on 29 August 2021 that he would briefly come out of retirement to play for them in the local Campeonato Minuano.

[8] He finished as champion of the +40 category tournament of ADIC (Asociación Deportiva de Integración Colegial), and also top scorer with 17 goals in 11 matches for the amateur (college) team Colegio Jesús María 2019, being the second championship won in the year after the Apertura, where he also ranked first in the scoring charts.

[40] On 27 May 2010, Abreu stood only five goals short of Uruguayan all-time goalscoring record, held by Héctor Scarone for 79 years.

[42][43] On 26 April 2019, Abreu was announced as the interim manager of Santa Tecla on an initial one-and-a-half month spell, with the parties holding the option open of keeping him as a player-coach or just as a player afterwards.

[45] In December 2019, Abreu was appointed player-coach at Boston River ahead of the upcoming campaign in the Uruguayan Primera División.
