Nacional In 2010, before retiring as a player, Gallardo obtained his coaching certificate from José Farías de Vicente López Technical School 62 in
Vicente López, Buenos Aires. Days after announcing his retirement from the Nacional de Montevideo squad which won the
2010–11 Uruguayan Primera División season championship, he accepted the team's offer to coach. Nacional defended their championship the next season, becoming the
2011–2012 champions for Gallardo. His assistants included
Matías Biscay,
Pablo Rodríguez and
Marcelo Tulbovitz. Gallardo later described managing Nacional as an "accelerated course", coaching players with whom he had played. He brought some of his assistants from Nacional de Montevideo, such as Matías Biscay and Marcelo Tulbovitz. Díaz' key players
Carlos Carbonero,
Manuel Lanzini and
Cristian Ledesma left the club, and players he had relegated (such as
Carlos Sánchez and
Rodrigo Mora) returned. River Plate bought only two players: attacking midfielder
Leonardo Pisculichi, who had been relegated to second division with
Argentinos Juniors, and goalkeeper Julio Chiarini from
Instituto de Córdoba. Gallardo's coaching style was praised by the Argentine press, with the team tying its all-time unbeaten record on 9 November with 32 undefeated games before losing to Estudiantes de La Plata three days later. Of the 32 games, eight were played for Ramón Díaz. River Plate led the
Torneo de Transición until it reached the
Copa Sudamericana semi-finals, where River would face the rival Boca Juniors. Planning to rest his key players for the semi-finals, Gallardo played a substitute team against second-place Racing Club and lost on an own goal by
Ramiro Funes Mori. Racing went on to win its first championship since
2001 by two points over River Plate. River eliminated Boca Juniors with a lone goal from
Leonardo Pisculichi in the second leg, played at the
Monumental Stadium. In the
2014 Copa Sudamericana Finals, Pisculichi scored again to draw 1–1 against
Atlético Nacional in the away leg at the
Estadio Atanasio Girardot. Defenders
Gabriel Mercado and
Germán Pezzella scored in the second leg at the Monumental, giving the unbeaten River Plate a 2–0 win and its first international title since 1997. Gallardo was the first River Plate player to win an international title as a player and a coach. He dedicated the victory to his mother, who had died shortly before the second game against Boca Juniors. In early 2015, Gallardo's River Plate competed in the
2015 Recopa Sudamericana as the 2014 Copa Sudamericana winners against
2014 Copa Libertadores champions
San Lorenzo. River won 1–0 at home in the first leg and 1–0 in the second, both goals scored by Carlos Sánchez. After a poor group stage which nearly eliminated them from the tournament, River Plate advanced to the
2015 Copa Libertadores Round of 16 as the worst team in the group stage to face Boca Juniors (the best team). River won the first leg at home 1–0, with a penalty kick by Carlos Sánchez. In the second leg, played at
La Bombonera stadium, the teams had drawn 0–0 at the half. Returning to the pitch for the second half, River Plate's players were attacked by Boca Juniors fans. After a one-hour delay, the match was suspended by a
CONMEBOL official. Days later, the organization disqualified Boca Juniors and River advanced to the tournament's quarter-finals. The team later reached the Libertadores final and played against Mexico's
Tigres. In the first leg, at the
Estadio Universitario, the game was scoreless. In the second leg, played at the Monumental, River won 3–0 with goals by
Lucas Alario, Carlos Sánchez, and
Ramiro Funes Mori for their first Libertadores championship in nine years. The next day, Gallardo's team travelled to
Osaka for the
2015 Suruga Bank Championship against
2014 J.League Cup winners
Gamba Osaka. The match was a 3–0 victory for River Plate, the team's fourth international title under Gallardo. Despite poor results in the
2015 Argentine Primera División, River later advanced to the semi-finals of the
2015 Copa Sudamericana to play against fellow Argentine side
Huracán. The two-legged series resulted in a 1–0 loss for River in the first leg at home, followed by a 2–2 draw in the second leg. This was Gallardo's first defeat in an international knockout stage as a coach. River played in the year-end
2015 FIFA Club World Cup, struggling to beat
2015 J1 League winners
Sanfrecce Hiroshima 1–0 in the semi-finals with a goal from
Lucas Alario and three saves in the first half by goalkeeper
Marcelo Barovero. They played poorly in the
final, losing 3–0 to European champions
Barcelona with goals by
Lionel Messi and
Luis Suárez. Gallardo was named the fifth-best football coach worldwide in 2015 by the
IFFHS.
2016–2022 River Plate were eliminated by runners-up
Independiente del Valle in the
2016 Copa Libertadores round of 16. River Plate won the
2016 Recopa Sudamericana against
2015 Copa Sudamericana champions
Independiente Santa Fe, defeating them 2–1 at home in the second leg after a scoreless first leg for another international title. In December of that year, Gallardo led River to the
2015–16 Copa Argentina: his first domestic cup as manager. River Plate then earned the right to play in the
2017 Copa Libertadores and the
2016 Supercopa Argentina against
2016 Primera División champion
Lanús, where it was defeated 3–0. River Plate advanced to the semi-finals of the
2017 Copa Libertadores against Club Atlético Lanús. After winning the first leg 1–0 at Monumental Stadium, they lost the second leg at
Estadio Ciudad de Lanús 4–2. River Plate lost the semi-finals 4–3 on aggregate. They defeated
Atlético Tucumán days later at the
2016–17 Copa Argentina final in Mendoza for their second consecutive
Copa Argentina. This gave River Plate the right to play the
2017 Supercopa Argentina against
2016–17 Argentine Primera División champions Boca Juniors, defeating Boca 2–0 on 14 March 2018. Except for their victory in the Supercopa Argentina, River Plate began 2018 with a losing streak in the
Primera División. They played well in the
2018 Copa Libertadores, however, reaching the
finals against Boca Juniors. It was the first time two Argentine teams faced each other in a Libertadores final; the last final had a two-legged home-and-away format, although the second match was played at the
Santiago Bernabéu because River Plate fans attacked Boca Juniors players at Monumental Stadium. River Plate and Boca Juniors drew the first match 2–2 at
La Bombonera, with goals by
Lucas Pratto and
Carlos Izquierdoz (own goal). The second match, at the Bernabéu, ended in a 1–1 draw; Pratto again scored for River and sent the match into extra time. River won 3–1, with goals by
Juan Fernando Quintero and
Pity Martínez. Despite missing the finals with a suspension for violating a previous penalty in the semi-finals against
Grêmio, Gallardo's coaching played a key role in the victory (considered one of the most important in Argentine football history). His coaching was praised by the press, and he was called one of the best River Plate managers of all time. After winning the
2019 Recopa Sudamericana, Gallardo became the most successful River Plate coach in history with ten titles. He is the most successful coach at the international level in club history to date, with seven international titles: two
Copa Libertadores (
2015 and
2018), the
2014 Copa Sudamericana, three
Recopa Sudamericanas (
2015,
2016 and
2019) and the
2015 Suruga Bank Championship. He is considered the greatest coach in River Plate history. Into the early 2020s, Brazilian teams showed a stronger performance than their counterparts in the CONMEBOL international tournaments, due to a higher competitiveness in their local league and a more favorable domestic economic situation. Although Gallardo displayed his ability to form competitive squads over the years in spite of factors such as key players leaving the roster, Argentina's growing economical disparity with Brazil's took its toll in River Plate's performance against its teams. After a tough fall in the
2021 Copa Libertadores quarter-finals against
Atlético Mineiro, he acknowledged their rivals beat them, playing "much better", and opted to focus on
that year's edition of the Argentine league. The squad eventually went on to win the championship and Gallardo equaled
Ángel Labruna's record of 22 titles as both a player and a coach for the team. Coming close to the expiration of his contract at the end of the season in the midst of speculations about his continuity, he decided to sign for yet at least one more year., stating that he will not continue on the team and that he will take a short break in his coaching career.
Al-Ittihad On 18 November 2023, Gallardo became the manager of
Al-Ittihad on a one-and-a-half-year contract after having taken a short break from coaching. Following a crushing 5–0 home defeat to
Al-Ettifaq, which confirmed their elimination from the
2024–25 AFC Champions League Elite and compounded a series of poor results, Gallardo was dismissed on 13 May 2024. Despite his sacking, he remained in charge for the final three matches of the season before officially departing on 2 July.
Return to River Plate On 5 August 2024,
River Plate announced Gallardo as their new head coach, replacing outgoing
Martín Demichelis. In his first season he finished fifth in the
Argentine league, won the
Superclásico 1–0 and reached the semifinals of the
CONMEBOL Libertadores, losing 3–0 on aggregate against
Atlético Mineiro. In his second year back at the club, River Plate got eliminated by
Platense, 4–2 on penalties, in the quarter-finals of the
Torneo Apertura, also getting eliminated of the
Club World Cup in the group stage, on the last match against
Inter Milan. In the second half of the year, River Plate failed to qualify to the Libertadores and instead qualified for the Sudamericana for the first time since 2014 after being eliminated from the Libertadores by
Palmeiras in the quarter-finals, eliminated from the Copa Argentina in the semifinals, eliminated from the
Torneo Clausura in the round of 16 and finishing fourth in the annual table, when they had to finish in the top three to qualify. To qualify for the Libertadores, rivals
Boca Juniors had to win the Torneo Clausura but failed to do so after being eliminated in the semifinals by
Racing Club. ==Playing style==
