Born in
San Luis, Quiroga began his career at
Newell's Old Boys in the
Argentine Primera División in 1997. The following year he was signed by
Sporting CP, where he spent six years with a season-long loan at Italian side
S.S.C. Napoli in
2000–01. He was relatively important in the
Lisbon team's
2000 conquest of the
Primeira Liga championship, playing alongside another Newell's youth graduate
Aldo Duscher who also joined in 1998; at Napoli he played with former Sporting teammate
Luis Vidigal, as they were eventually relegated from
Serie A. In 2004, Quiroga moved to
VfL Wolfsburg, a club that acquired a number of Argentine players in that timeframe (
Oscar Ahumada,
Andrés D'Alessandro,
Diego Klimowicz and
Juan Carlos Menseguez). A regular in the lineups from 2004 to 2007, he only appeared in 12
Bundesliga matches in
his last year, subsequently returning to Argentina and joining
Club Atlético River Plate. In 2010, the 32-year-old Quiroga signed for
Club Atlético Huracán. He retired three seasons later, with
All Boys also in his country's top division. ==International career==
