Fabricio Coloccini

Boca Juniors

Born in Córdoba, Córdoba Province, Coloccini started his career in the youth team of Argentinos Juniors, but made his professional debut in 1998 with Boca Juniors. He made one league appearance, as a starting line-up, in his one and only season with Boca. He played in Walter Samuel's position, who received a call-up from the Argentina national team. Coloccini scored in his only match, leveling the scores in a 2–2 draw with Unión de Santa Fé.

AC Milan

In December 1999, at the end of the Apertura championship, Coloccini moved to AC Milan. He was at the centre of a controversy between Boca and Milan, because the transfer from Argentina to Italy was not agreed between the clubs. Instead, Milan arranged terms with Coloccini's father (also a former football player), who exercised his parental rights to remove the minor from Argentina. After that, FIFA ordered Milan to pay Boca compensation. On 22 January 2000, less than a month since moving to Italy, Coloccini turned 18 and joined AC Milan's senior team that at the time also featured a number of his fellow countrymen and national team players, namely Roberto Ayala, Andrés Guglielminpietro, and José Chamot, the latter of whom joined the club in the same transfer window. Despite manager Alberto Zaccheroni's preference for formations with three center backs and a lack of undisputed starters other than the team's captain Paolo Maldini, Coloccini did not make his debut for Milan during that season.

Coloccini was part of the Argentina Under-20 that won the 2001 FIFA World Youth Championship, as well as the gold medal winning Argentina team at the 2004 Summer Olympics. With the Argentine senior squad, he made his international debut on 30 April 2003, in a 3–1 friendly win over Libya, in Tripoli. The following year, he was a member of the team that reached the final of the 2004 Copa América, only to lose to Brazil 4–2 on penalties, following a 2–2 draw. He scored his only international goal on 4 September 2004, in a 3–1 away win over Peru, in Lima, in a 2006 FIFA World Cup qualifier. He later participated in the 2005 Confederations Cup, where Argentina once again finished as runners-up to Brazil following a 4–1 defeat in the final. At the 2006 FIFA World Cup, Coloccini played in two games, as a substitute against the Netherlands, and starting against hosts Germany in the quarter-finals, which ended in a 5–3 penalty shootout loss following a 1–1 draw. Coloccini was an unused substitute in Argentina's World Cup qualifier against Brazil on 6 September 2009. He was absent from the national team in the 2010 FIFA World Cup. Due to his great form throughout 2012, Coloccini was recalled to the Argentina squad under new manager Alejandro Sabella for the FIFA World Cup qualifiers against Paraguay and Peru in September 2012. Coloccini played the full 90 minutes in a 5–2 win over Paraguay on 10 September, a game which sealed Argentina's place in the 2014 FIFA World Cup in Brazil.

On April 1, 2022, Coloccini was announced as the new Venezuela U-20 manager. Coloccini has served as the assistant coach of Fernando Gago for Guadalajara, Boca Juniors, Necaxa and Universidad de Chile. In June 2026, he assumed as caretaker manager of Universidad de Chile after Gago suffered a heart attack.

As a defender, Coloccini was known for his physical strength, consistency, experience, fearless challenges, stamina, and in particular, his ability in the air, which made him a goal-threat from set-pieces in the opposing penalty area. Although he normally played as a centre-back, he was also deployed as a right-back on occasion. Regarded as a promising defender in his youth, he was named one of the 100 best young footballers in the world by Don Balón in 2001.
