Javier Mascherano, Argentinian footballer
Javier Alejandro Mascherano (born 8 June 1984) is an Argentine former professional footballer who played as a defensive midfielder or centre-back.

Mascherano began his career at River Plate, where he earned his first senior honours, the Argentine Primera División, in 2003–04. He moved to Brazilian side Corinthians in 2005, winning the Brazilian Série A in his first season. Mascherano then moved to Europe, signing for Premier League side West Ham United, but his brief time at the club was blighted by unusual contract terms with Global Soccer Agencies. At the beginning of 2007, he joined Liverpool on loan, reaching the final of the UEFA Champions League, before he signed with the club for £18.7 million. After three years playing for Liverpool, Mascherano joined Barcelona in 2010, where he changed his position of defensive midfielder to full central defender. With Barcelona, he won five La Liga championships, two UEFA Champions League titles, and two FIFA Club World Cups, among other honours.

Mascherano made 147 appearances for the Argentina national team and is the second most capped player in the country's history (after Lionel Messi). From his debut in 2003 until his retirement in 2018, he represented the nation at five Copa América tournaments, finishing runner-up in 2004, 2007, 2015, and 2016, and four FIFA World Cups, reaching the 2014 final. He twice won a gold medal at the Summer Olympics, in 2004 and 2008, becoming the first male footballer to achieve this double feat since Hungarian defender Dezső Novák in 1968. Between 2008 and 2011, Mascherano served as the captain of Argentina.
