Gustavo Quinteros

Quinteros was unable to make a breakthrough at Newell's, only featuring as an unused substitute in a reserve team match in July 1985. Six months later, he joined Central Córdoba de Rosario, where he would make his senior debut. In 1987, Quinteros signed for Talleres de Remedios de Escalada, being a part of the squad which won the 1987–88 Primera B Metropolitana. In the following year, after a failed move to a Primera B Nacional side, he moved to Bolivia and joined Universitario de Sucre. After scoring eight goals for Universitario de Sucre, Quinteros moved to The Strongest for the 1989 season. At the latter club, he was converted into a centre-back, and established himself as a starter in that position. He later spent a one-season spell at San José, before returning to Strongest in 1994. After the 1994 World Cup, Quinteros returned to his birth nation, signing a contract with San Lorenzo after the club paid a US$ 170,000 fee. He would never establish himself as a starter at the club, only making his Argentine Primera División debut on 6 May 1995, in a 2–1 away win over Deportivo Mandiyú. Quinteros signed for Argentinos Juniors in 1997, before moving back to Bolivia in 1999 with Jorge Wilstermann. He retired with the latter club at the end of the season, aged 34.

Quinteros initially obtained Bolivian nationality to "free up foreign quota", but was later called up to the Bolivia national team in 1993. He made his full international debut on 29 January of that year, starting and scoring the opener in a 3–1 friendly win over Honduras at the Estadio Félix Capriles in Cochabamba. Quinteros also played in the 1993, 1995 and 1999 editions of the Copa América, aside from the 1994 FIFA World Cup and the 1999 FIFA Confederations Cup. He represented the nation on 26 occasions.

Argentinos Juniors

Shortly after retiring, Quinteros returned to Argentinos Juniors to work as their youth manager. In July 2003, he was named in charge of the first team, replacing Ricardo Gareca, but was himself replaced by Sergio Batista in December of that year.

Blooming

On 1 June 2005, Quinteros moved back to Bolivia and took over Blooming after the departure of Víctor Hugo Antelo. He led the club to the 2005 Apertura title, but resigned in June 2006, after a mid-table finish in the Clausura.

San Martín de San Juan

Shortly after leaving Blooming, Quinteros was named manager of San Martín de San Juan on 27 June 2006. On 6 February of the following year, however, he was sacked.

Blooming return

20 days after leaving San Martín, Quinteros returned to Blooming.

Bolívar

On 25 December 2008, after previously agreeing to a new one-year contract at Blooming, Quinteros was appointed manager of Bolívar. On 10 November 2009, he left the latter club.

Oriente Petrolero

On 7 January 2010, Quinteros was presented as manager of Oriente Petrolero. He won the season's Torneo de Invierno, before being announced as manager of the Bolivia national team on 5 November; Oriente still managed to retain Quinteros as manager until the Clausura tournament, also won by the club.

Bolivia national team

Quinteros officially took over the Bolivia national team on 29 November 2010. Under his guidance, Bolivia failed to win a single match…

Quinteros was born in Cafferata, a small town in the Santa Fe Province. A midfielder, he joined the youth sides of Newell's Old Boys at the age of 13, but only spent a year at the club before leaving. He returned to the side at the age of 17, while studying biochemistry and pharmacy at the National University of Rosario.
