Early career Allegri started his managerial career in 2004, serving as the manager of
Serie C2 team
Aglianese, the club where he spent his two final years as a player. Following an impressive season with them, Allegri was called to head
Grosseto, then in
Serie C1, but his experience with the
biancorossi proved not to be as successful as with Aglianese and he was ultimately sacked shortly after the beginning of the 2006–07 Serie C1 season. Shortly after being sacked by Grosseto, Allegri agreed to rejoin his mentor
Giovanni Galeone at
Udinese, becoming part of his coaching staff. However, this practice proved to be forbidden by the Italian football laws because he was still contracted with the Tuscan club, which caused Allegri to be disqualified for three months in early 2008.
Sassuolo In August 2007, Allegri became head coach of ambitious
Serie C1 team
Sassuolo, who Allegri managed to lead quickly into the top league spots. On 27 April 2008, Sassuolo mathematically ensured the 2007–08 Serie C1/A league title, thus winning a historical first promotion to
Serie B for the
neroverdi.
Cagliari On 29 May 2008, Allegri was announced as new head coach of
Cagliari in the
Serie A, replacing
Davide Ballardini. Despite a disappointing start, with five losses in the first five league matches, Allegri was confirmed by club chairman
Massimo Cellino and later went on to bring his team up to a mid-table placement in December. On 9 December, following a 1–0 home win to
Palermo, Cagliari announced they had agreed a two-year contract extension with Allegri, with a new contract that was set to expire on 1 June 2011. The contract was then revealed to have been signed in October, in the midst of the
rossoblu's early crisis. He completed the
2008–09 season in an impressive ninth place, their best result in Serie A in almost fifteen years, which was hailed as a huge result in light of the limited resources, the lack of top-class players, and the high quality of Cagliari's attacking football style, which led the
Sardinians not far from
UEFA Europa League qualification.
AC Milan and
Robinho in 2012|258x258px Allegri was released from his contract by Cagliari on 17 June 2010, under request of Serie A giants
AC Milan, who were interested in appointing him as their new manager. On 25 June, Allegri was officially appointed as the new manager of Milan. In his first season in charge, Allegri led Milan to their first championship title since
2004, beating title incumbents and
cross-city rivals Inter Milan in both league fixtures; at the time, only
Roberto Mancini had achieved that feat at a younger age. That was as far as his success went for that season, however. A semi-final
Coppa Italia knockout at the hands of
Juventus followed by a quarter-final
UEFA Champions League knockout at the hands of
Barcelona left Milan fighting on only one front towards the end of the season—the
Scudetto. Even that was to be lost, however, with the
Rossoneri finishing in second place to Juventus and therefore qualifying for
next season's Champions League group stage. The season was also marked with controversy however, as in the second half of the season, Milan had a goal by
Sulley Muntari disallowed in a key match against title rivals Juventus at the
San Siro, after they had already been leading 1–0; the match eventually ended in a 1–1 draw.
Juventus On 16 July 2014, Allegri was appointed as the new head coach of
Juventus, replacing
Antonio Conte who had resigned the day before. Although the decision to hire Allegri was initially met with ambivalence, On 13 May 2015, Allegri guided Juventus to the
Champions League final by defeating defending champions
Real Madrid in the semifinals, 3–2 on aggregate; it had been twelve years since the Bianconeri had last appeared in the final, eventually losing to Milan 3–2 on penalties in
2003. A week later, on 20 May 2015, Allegri guided Juventus to a domestic
double by helping the club win their record tenth
Coppa Italia, defeating
Lazio 2–1 in
extra time. The Old Lady last won the trophy in 1995, breaking their twenty-year drought of having not won the competition, and making them the first team in Italy to win the trophy ten times. On 6 June 2015, Juventus were defeated by
Barcelona, 3–1, in the 2015
UEFA Champions League final. On 6 July 2015, almost a year after signing with Juventus, Allegri signed a one-year extension to his current contract keeping him at the club until the end of the 2016–17 season. On 8 August 2015, Allegri led Juventus to a 2–0 victory over Lazio in the
Supercoppa Italiana, with new signings
Mario Mandžukić and
Paulo Dybala scoring the goals. Allegri was included in the 10-man shortlist of nominees for the
2015 FIFA World Coach of the Year Award, but was later not included among the three finalists, despite almost completing a treble in his first season as Juventus' coach. However, on 14 December 2015, Allegri won the
Serie A Coach of the Year award; and later on 7 March 2016, his second ever
Panchina d'Oro for his success with Juventus during the 2014–15 season. On 25 April, Juventus were crowned
2015–16 Serie A champions; after initially struggling during the first ten league matches of the season, Juventus went on an unbeaten streak and won 24 of their next 25 league games to come back from 12th place to defend the title. The team's unbeaten streak ended after 26 matches, and was broken following a 2–1 away loss to
Verona on 8 May. On 6 May, Allegri extended his contract as Juventus manager to 2018. On 21 May, he led Juventus to the domestic double once again after a 1–0 victory over Milan in the
2016 Coppa Italia Final, the first team in Italy to win back-to-back doubles. On 17 May 2017, Allegri led Juventus to their
12th Coppa Italia title in a 2–0 win over Lazio, becoming the first team to win three consecutive championships. Four days later on 21 May, following a 3–0 win over Crotone, Juventus secured their sixth consecutive Serie A title, establishing an all-time record of successive triumphs in the competition. On 3 June 2017, Allegri entered his
second Champions League Final in three years with Juventus, but suffered a 4–1 defeat to defending champions Real Madrid. On 7 June, Allegri renewed his contract with Juventus until 2020. Allegri took charge of his 200th game with Juventus on 9 February 2018, a 2–0 away win over
Fiorentina. On 9 May 2018, Allegri won his
fourth consecutive Coppa Italia title, in a 4–0 win over Milan. Four days later on 13 May, following a 0–0 draw with Roma, Allegri secured his fourth consecutive Serie A title, becoming the first manager in
Europe's top five leagues to win four consecutive doubles. On 17 May 2019, after Juventus had already secured its fifth straight Scudetto under Allegri on 20 April, Juventus announced that he would leave the club at the end of the season. Allegri left Juventus in 2019 with a win percentage of 70.48%, the highest in the history of Juventus to date.
Return to Juventus On 28 May 2021, Juventus announced Allegri's return to the club as manager after two years away from management, replacing the sacked
Andrea Pirlo on a four-year contract. Allegri's first match since his return came on 22 August, in a 2–2 away draw against
Udinese. On 23 November, Juventus lost 4–0 to
Chelsea at
Stamford Bridge; the team had not lost with such disadvantage since February 2004. On 15 January 2022, Allegri reached his 300th bench with Juventus, in the league return match to Udinese. On 16 March, Juventus were eliminated from the
2021–22 UEFA Champions League after a 3–0 home defeat to
Villarreal. On 11 May, following to the
Bianconeri's 4–2 loss after extra time to
Inter in the Coppa Italia final, the
2021–22 season ended up trophyless, for the first time since
2010–11, under
Luigi Delneri's guide. On 2 November, he featured in his
100th Champions League match in a 2–1 home defeat against
Paris Saint-Germain. The match against PSG was Juventus' last Champions League match of the season; the team made their worst-ever Champions League campaign, having won only three points, from a victory and five defeats, with 13 goals conceded during the group stage. For the first time since
2013–14, Juventus placed third in the group stage, because of a better goal difference with Israeli team
Maccabi Haifa, obtaining access to the
UEFA Europa League. On 13 January 2023, Juventus ended an eight-game winning streak in Serie A with no goals conceded following by a 5–1 loss to Napoli; Juventus had not conceded so many goals since
Pescara–Juventus 5–1 (30 May 1993), in which Allegri himself scored the first goal the match while playing for Pescara. Allegri's second season upon his return ended up trophy less again after a 2–1 loss to
Sevilla after extra-time in the Europa League semi-finals. The last manager not to win any trophy in two seasons was
Rino Marchesi, who coached Juventus from 1986 to 1988. On 15 May 2024, Allegri was sent off in Juventus's 1–0 victory over Atalanta in the
2024 Coppa Italia final; with the victory, he became the first manager to win the title five times. Following the game, he was also reported to have angrily attacked the referees, threatened a journalist and waved off sporting director
Cristiano Giuntoli during the post-match celebrations. He was sacked just two days later on 17 May, reportedly in large part due to the incident.
Return to AC Milan On 30 May 2025, he was appointed as the new AC Milan manager replacing
Sérgio Conceição, returning to the club 11 years after his first tenure ended. == Style of management ==
