Walter Mazzarri

Walter Mazzarri (born 1 October 1961) is an Italian professional football manager and former player.

Mazzarri, a midfielder and a product of Fiorentina's youth system, made his professional debut in 1981 for Pescara of Serie B, and played a short Serie A stint in Cagliari the following season, before being sold to Reggiana.

He had his longest period at Empoli, who won promotion to Serie A for the first time during his time with the Tuscan side.

After several spells with mostly minor teams, including a two-year stint with Acireale where he was part of the team that won a historic first promotion to Serie B, and then playing in the Italian second tier in 1993–94, Mazzarri ended his playing career in 1995 with Sassari Torres.

Mazzarri started his coaching career as Renzo Ulivieri's assistant at Napoli in 1998.

His first spell in charge came in 2001–02 for Sicilian Serie C2 team Acireale, where he had been a player from 1992 to 1994.

Subsequently, he returned to his native Tuscany to coach Pistoiese of Serie C1 in 2002–03 and Livorno of Serie B in 2003–04, bringing the amaranto led by Cristiano Lucarelli back to Serie A.

He was coach of Reggina from 2004 to 2007, leading the Calabrian side to Serie A survival in three consecutive seasons, the last obtained on the final day of the season despite an 11-point deduction.

After a 14-year playing career with Italian clubs including Reggiana and Empoli, Mazzarri coached several smaller Italian sides and in 2007 took up a managerial position with Sampdoria.

With the help of the attacking partnership of Antonio Cassano and Giampaolo Pazzini, he led the team to qualify for the UEFA Cup in his first season and subsequently reached the Coppa Italia final the next year.

In May 2007, Mazzarri was made an honorary citizen of Reggio Calabria, after helping the club avoid relegation during the 2006–07 Serie A season.

On 31 May 2007, he was announced as the new Sampdoria coach.

He served as Sampdoria boss for two seasons, overseeing a considerable improvement in results, thanks to the likes of the attacking duo of Antonio Cassano, who publicly praised Mazzarri's coaching abilities, and Giampaolo Pazzini.

Sampdoria's 2007–08 campaign ended in an impressive sixth place, which ensured qualification for the UEFA Cup.

Mazzarri's fortunes declined slightly in 2008–09, as the Blucerchiati ended their campaign in 13th place; despite this, he managed to guide his team into the Coppa Italia Final, notably defeating champions Inter 3–1 on aggregate in the semi-finals, before losing on penalties to Lazio in the final.

Mazzarri left Sampdoria by mutual consent at the end of the 2008–09 season.

In 2009, he joined Napoli, where he implemented a 3–4–3 formation with which he later became associated.

On 6 October 2009 he was appointed manager of Napoli, replacing Roberto Donadoni.

He finished his debut season in sixth place in Serie A, and was handed a new three-year contract at the end of the campaign.

In 2010–11, Mazzarri's Napoli finished third in the league and qualified directly for the group phase of the 2011–12 UEFA Champions League – their first time in Europe's premier competition in 21 years.

His team were known for using an attacking 3–4–3 formation with a frontline three of Ezequiel Lavezzi, Marek Hamšík and Edinson Cavani, who were nicknamed I tre tenori ("The Three Tenors"); Mazzarri also employed variations upon this system on occasion, such as 3–5–2 formation, the 3–4–1–2, and the 3–5–1–1.

They finished second in their Champions League group, behind Bayern Munich but ahead of Manchester City and Villarreal, to meet Chelsea in the last 16.

Napoli won 3–1 at home in the first leg; they were subsequently beaten 4–1 at Stamford Bridge after extra time, being eliminated by the eventual champions.

With the attacking trio of Ezequiel Lavezzi, Edinson Cavani and Marek Hamšík, nicknamed I tre tenori ("The three tenors"), he helped the team qualify for the UEFA Champions League for the first time in the club's history in 2011, and won the Coppa Italia the following season, the club's first trophy in over 20 years.

In his final season with the team, he managed a second-place finish in Serie A, the club's best league finish in over 20 years.

Napoli won the 2012 Coppa Italia Final over undefeated league champions Juventus on 20 May; this was Juventus's only loss of the season, and Napoli's first title in over 20 years.

On 11 August that year, the club suffered a controversial 4–2 extra-time defeat to Juventus in the 2012 Supercoppa Italiana, which saw two Napoli players sent off as well as Mazzarri.

He parted with the club before the 12th matchday, while they were five points below their season objective of the third position.

In 2013, he moved to Inter but was sacked halfway through his second season with the club.

He left the Azzurri on 19 May 2013, after leading them to a 2nd-place finish and a spot in the Champions League at the end of the 2012–13 Serie A season; this was the club's best league finish in over 20 years.

Mazzarri was officially appointed as the Inter manager on 24 May 2013, after Andrea Stramaccioni was dismissed for a poor performance in the 2012–13 season.

On 2 July 2014, he signed a one-year extension to tie him to the team until 30 June 2016.

He was sacked by Inter after a series of disappointing results on 14 November 2014, leaving the club in ninth place.

He later managed Torino in Serie A, and had one year in charge of Watford in England's Premier League in 2016–17.

In 2023, after a gap year from his last management for Cagliari, he returned to Napoli but was sacked in February 2024 after three months.

On 21 May 2016, Watford confirmed they had reached an agreement with Mazzarri to become Head Coach from 1 July 2016 on a three-year contract.

He joined a club owned by his compatriot Giampaolo Pozzo, and worked without being able to speak English.

Mazzarri secured Watford's Premier League status that season, finishing one place above relegation in 17th, a four-place dip on their previous campaign.

It was announced on 17 May 2017 that his contract would be terminated at the end of his first season at the club.

On 4 January 2018, Mazzarri was appointed manager of Torino, replacing Siniša Mihajlović.
