Martín Demichelis

River Plate

Born in Justiniano Posse, Córdoba, Demichelis started playing professionally in 2001, with Buenos Aires-based River Plate, having arrived at the club's youth system three years earlier. He made his first-team – and first division – debut on 2 September 2001 in a game against Estudiantes, scoring his only goal for the team against Rosario Central. On 28 April 2002, River Plate goalkeeper Ángel Comizzo was sent off with a minute of regulation time remaining against Racing Club, leaving Demichelis to take over in goal. He faced a direct free kick that hit the wall and was countered for the only goal of the game by Nelson Cuevas, as River won the Clausura title.

Bayern Munich

Demichelis signed for Bayern Munich in the 2003 summer, for €4.5 million. His first season in the Bundesliga was not very positive as he suffered a number of minor injuries, appearing in only 14 league games (21 in total) as the Bavarians finished in second position; in early 2004 he appeared in his only game with the reserves, against Stuttgarter Kickers. Under new coach Felix Magath, Demichelis became a regular starter for Bayern, appearing in 75 official matches in two seasons combined as the team won back-to-back doubles, achieving a total of four during his spell. Returning Bayern boss Ottmar Hitzfeld successfully reconverted Demichelis from a defensive midfielder into a central defender. In 2008–09 he netted a career-best four goals in 29 games, but the title was lost to…

Demichelis was first called up for Argentina to compete at the 2005 FIFA Confederations Cup in Germany, where he was unused by the eventual runners-up. He made his debut under José Pekerman on 12 November 2005 that year, in a 3–2 friendly loss to England at the Stade de Genève in Switzerland, playing as a defensive midfielder; he was not chosen for the 2006 FIFA World Cup. On 11 September 2007, Demichelis scored his first international goal, heading the only goal of a friendly against Australia at the Melbourne Cricket Ground. He suffered a facial injury during an exhibition game with Germany on 3 March 2010, being sidelined for three weeks, and later being selected for the year's World Cup in South Africa. Under Diego Maradona, he played in all of Argentina's games at the tournament, partnering Nicolás Burdisso in central defence in an eventual quarter-final exit; on 22 June, he scored the first goal in the 2–0 group stage win against Greece. Demichelis lost his place in the national side in November 2011, after a World Cup qualifier against Bolivia. A two-and-a-half-year absence followed, until he was included in Alejandro Sabella's provisional 30-man squad for the 2014 World Cup. He ended up making the final list. On the bench for the team's first four games, Demichelis made his debut in the tournament in the 1–0 quarter-final win over Belgium in which he played the full 90 minutes, taking the place of Federico Fernandez. He went on to start in the semi-finals where his…

Early years

In May 2017, immediately after retiring, Demichelis remained at Málaga as assistant manager to Míchel, replacing Weligton who had returned to Brazil due to injury. He remained in employment after the head coach was dismissed in January, but was not as involved under his successor José González. Demichelis returned to Bayern in June 2019, to manage the under-19 team. On 2 April 2021, it was announced that he and Danny Schwarz would replace Holger Seitz as Bayern Munich II manager, becoming the club's historical first non European head coach. His first match as coach of a senior team was on 17 July, a 3–0 win at FC Augsburg II on the first day of the Regionalliga Bayern season.

River Plate

In October 2022, Demichelis obtained a UEFA Pro coaching license after passing the yearly course organised by the Italian Football Federation. On 16 November, River Plate appointed Demichelis as their new head coach, on a 3-year contract. On 28 January 2023, Demichelis made his debut with a 3–0 win against Central Córdoba. On 15 July, River Plate secured the league title with three games left to play, giving Demichelis his first title as manager. On 27 July 2024, Demichelis was dismissed from his position.
