Early years Sergio Scariolo started his
coaching career in the early 1980s, as the assistant coach of
Basket Brescia, the team of his hometown, and
Scavolini Pesaro. In 1985, he became the coach of Italy's military national team, with whom he won the world championship. As assistant coach of
Valerio Bianchini in Pesaro, Scariolo won its first
Italian Serie A championship in 1988.
First successes in Italy (1989–1997) In 1989, Bianchini became the new coach of
Virtus Roma and Scariolo was hired as new head coach of
Pesaro. In the 1989–90 season, Scariolo's Scavolini was able of winning another Italian league title, defeating
Pallacanestro Varese 3–1 in the national finals. Aged 29, Scariolo became the youngest coach ever to win the trophy. In the same season, the team also reached the
FIBA Korać Cup Final, which lost against
Joventut Badalona. In 1990–91 season, the club arrived 7th in the regular season and was ousted in the national quarterfinals by
Phonola Caserta. However, Pesaro succeeded in reaching the
European Champions Cup Final Four, but it was defeated 93–84 in the semi-finals by
KK Split, which then won the trophy. In the following year, he unexpectedly moved to Aurora Desio, of the
Italian 2nd Division. After two seasons in which he failed to reach the promotion, he left the club. In 1993, Scariolo was hired by
Fortitudo Bologna, a team which was becoming more and more ambitious under the new ownership of the entrepreneur Giorgio Seragnoli. In 1994, he was awarded as Coach of the Year of the Italian Serie A. In 1994–95 season, Fortitudo arrived second in the regular season but it was defeated in the national semi-finals by
Benetton Treviso, while in 1995–96, Scariolo's team succeeded in reaching the national finals, the first ones in the history of the club, but Fortitudo was defeated 3–1 by
Olimpia Milano.
Triumphs in Spain (1997–2008) In 1997, he moved to Spain, a nation which deeply marked his entire career. With Scariolo as head coach,
TAU Vitoria reached its first
Spanish Championship final in 1998 and won a
Spanish King's Cup title in 1999. In 1999, Scariolo was hired by
Real Madrid, one of the most important clubs of the
Liga ACB. In the
first season, he immediately led Real to win the Spanish national league title, defeating 3–2, Real's historic rival
FC Barcelona; the team also reached the
EuroLeague's quarterfinals, which lost against Fortitudo Bologna. However, in the following season, Real was defeated 3–0 by Barcelona in the national finals, while in
2001–02, it was ousted in the quarterfinals by
CB Estudiantes and Scariolo was sacked. From 2003 to 2008, Sergio Scariolo was the head coach of the Spanish club
Unicaja Málaga, which, under his tenure and thanks to the leadership of
Jorge Garbajosa, lived its so-called "golden age". In 2005, Málaga won the
Spanish King's Cup title against Real Madrid and in the next year, during the
2005–06 season, it won its first-ever
Spanish League championship, defeating TAU Vitoria 3–0 in the national finals. The club finished its best years to date, by qualifying for the
2007 Euroleague Final Four, where it was defeated in the semi-finals by
CSKA Moscow, and thus finished in third place in the
EuroLeague. In October 2007, Unicaja faced the
NBA's Memphis Grizzlies in a
friendly match, and they defeated the Grizzlies, by a score of 102–99. That was one of the few times that an NBA team has lost to a foreign club.
Difficult years in Moscow, Milan and Vitoria (2008–2014) From 2008 to 2010, Scariolo served as the head coach of the Russian club
BC Khimki Moscow. In both seasons he arrived second, losing the national finals against
CSKA Moscow. In 2009, Scariolo's Khimki was also defeated 80–74 in the
EuroCup Final against
Lietuvos Rytas. On 20 December 2010, Scariolo and the club mutually agreed to rescind the contract. In 2011, Scariolo returned to Italy, becoming the new head coach of
Olimpia Milano. In 2011–12
EuroLeague, Milan reached the Top16, but did not pass the round. Scariolo's team reached the national finals, but it was defeated 4–1 by
Monte Paschi Siena. In the following season, Olimpia failed in reaching EuroLeague's Top16 and was once again defeated 4–3 by Siena in the playoffs' quarterfinals and Scariolo resigned from his post. In June 2013, Scariolo became the head coach of
Laboral Kutxa, a club which he had already coached during the late 1990s. However, after poor results both in national and European competitions, he was fired at the end of the 2013–14 season.
NBA champion with the Toronto Raptors (2018–2021) On July 25, 2018, Scariolo was hired by the
Toronto Raptors as an assistant coach, aiding them to win their first NBA championship. Scariolo became the first Italian coach and the second Italian ever, after the shooting guard
Marco Belinelli, to become an NBA champion. On 26 February 2021, Scariolo served as interim head coach of the Raptors for a game against the
Houston Rockets after head coach
Nick Nurse and five assistants missed the game due to the NBA's health and safety protocols; Toronto won the game 122–111. Raptors point guard
Kyle Lowry collected the game ball after the game and presented it to Scariolo as a memento.
At the head of Virtus Bologna (2021–2023) On 18 June 2021, Scariolo signed a three-year deal with
Virtus Bologna, of the Italian
Lega Basket Serie A (LBA). On 21 September, the team won the second
Supercup in its history, defeating
Olimpia Milano 90–84. Moreover, after having ousted
Lietkabelis,
Ulm and
Valencia in the first three rounds of the
playoffs, on 11 May 2022, Virtus defeated
Frutti Extra Bursaspor by 80–67 at the Segafredo Arena, winning its first
EuroCup and qualifying for the
EuroLeague after 14 years. However, despite having ended the regular season at the first place and having ousted 3–0 both
Pesaro and
Tortona in the first two rounds of playoffs, Virtus was defeated 4–2 in the national finals by Olimpia Milan. On 29 September 2022, after having ousted Olimpia Milano in the semifinals, Virtus won its
third Supercup, defeating 72–69
Banco di Sardegna Sassari and achieving a back-to-back, following the 2021 trophy. However, despite good premises Virtus ended the
EuroLeague season at the 14th place, thus it did not qualify for the playoffs. Moreover, the team was defeated in the
Italian Basketball Cup final by
Brescia. In June, after having ousted 3–0 both Brindisi and Tortona, Virtus was defeated 4–3 by Olimpia Milan in the national finals, following a series which was widely regarded among the best in the latest years of Italian basketball. On 15 September, just a few weeks before the season start, Scariolo was fired following controversial statements regarding the new roster and the upcoming season.
Return to Real Madrid (2025–present) On 3 July 2025, Scariolo signed a three-year deal with Real Madrid, returning to the Spanish powerhouse after 23 years. ==National team career==
