Javier Alejandro Mascherano (; born 8 June 1984) is an Argentine professional football coach and former player. As a player, he played as a centre-back or defensive midfielder, most notably for Liverpool, Barcelona and the Argentina national team.

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.

Club career

River Plate

Born in San Lorenzo, Santa Fe, Mascherano came through the youth ranks at River Plate in Buenos Aires, Argentina. However, before making his club debut he made his name representing Argentina.

Mascherano won his first silverware when River won the 2003–04 Clausura championship. In the 2004 Copa Libertadores River reached the semi-final, but lost on penalties to arch-rivals Boca Juniors. Around this time several clubs including Real Madrid, and Deportivo La Coruña declared an interest in signing Mascherano, but River Plate turned down all offers, saying that none of the interested parties were prepared to pay enough.

2004–05 was not a successful season for River, finishing third in the Apertura Championship and only tenth in the Clausura. In the Copa Libertadores River again lost in the semi-final, this time to São Paulo. After the Confederations Cup in Germany, Brazilian club Corinthians acquired Mascherano from River Plate for US$15 million.

Corinthians

The Brazilian Série A runs from April, so Mascherano joined Corinthians in mid-season. After playing only nine games for his new club, in September 2005, Mascherano suffered a stress fracture to his left foot causing him to miss the end of the season. He returned to Argentina to be operated on by the national team doctor and recuperate. Corinthians, however, still claimed the 2005 Série A championship with the team captained by Mascherano's Argentine compatriot, Carlos Tevez.

In total, Mascherano was out of action for six months, only returning on 5 March 2006. Corinthians were forced to start their 2006 Copa Libertadores without Mascherano, but he returned in time for the Round of 16 tie against River Plate, which Corinthians lost. The 2006 Brazilian Série A also went badly for Corinthians, and at one stage they were battling against relegation. In June, the league season was interrupted for the 2006 World Cup.

Although his performance drew the attention of European clubs, he stated his desire to remain with Corinthians to help with the relegation battle, and postponed any transfer until January at the earliest. Hours before the northern summer 2006 transfer window closed, however, Mascherano joined West Ham United for an undisclosed fee, along with teammate Carlos Tevez.

West Ham United

During the summer of 2006, Mascherano was linked with top clubs around Europe; he stated he would relish playing in Spain for Real Madrid or Barcelona, but eventually signed for West Ham United in the English Premier League alongside Carlos Tevez. Mascherano holds an Italian passport due to his ancestry from Sicily.
