Fabricio Tomás Coloccini (Spanish: [faˈβɾisjo koloˈtʃini]; Italian: [kolotˈtʃiːni]; born 22 January 1982) is an Argentine former professional footballer who played as a centre-back.

After making his reputation at Deportivo La Coruña he joined Newcastle United in August 2008 and, in July 2011, was promoted to club captain.

Instead, Milan arranged terms with Coloccini's father (also a former football player), who exercised his parental rights to remove the minor from Argentina.

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.

From 2001 to 2004, Coloccini served three consecutive loans in La Liga: Alavés (netting six league goals), Atlético Madrid, and Villarreal, where he was always first-choice.

[5] During his three-and-a-half-season stint, he was an undisputed starter, and appeared in all the matches during 2007–08 netting four goals, good enough for a UEFA Intertoto Cup berth for the club.

Since his debut, Coloccini was one of the most consistent inclusions in Newcastle's squad, and formed a partnership with fellow newcomer Sébastien Bassong in his first season.

Despite Newcastle's relegation, Coloccini stayed on and was the mainstay of the club's defence all season, partnering the likes of Steven Taylor, Mike Williamson, Fitz Hall and Tamás Kádár in the sturdiest rearguard of the championship.

The club was eventually promoted back to the Premier League as champions, and Coloccini's great contributions awarded him a place in the Championship's Team of the Year.

He continued his fine form for Newcastle into April, reforming his partnership with Mike Williamson after a brief time with Steven Taylor in January.

[17] On 5 July 2016, Coloccini mutually agreed with Newcastle that his contract would be terminated, with him signing for Primera División side San Lorenzo that same day.

[22] 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.

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.

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.
