The decision was made in a crisis meeting this afternoon between President Andrea Agnelli, directors and the coach.
An announcement was made at 13.40 UK time.
“Juventus Football Club announces that Maurizio Sarri has been relieved of his post as coach of the First Team,” read the statement.
“The club would like to thank the coach for having written a new page in Juventus’ history with the victory of the ninth consecutive championship, the culmination of a personal journey that led him to climb all the divisions of Italian football.”
He won the first Italian trophy of his career, their ninth Serie A title in a row, but only one point ahead of Inter and with none of the attractive football that was expected.
His position was already shaky after losing the Italian Supercup to Lazio in December, then the Coppa Italia Final to Napoli in June.
Last night’s Champions League exit to Olympique Lyonnais proved the final straw, going out on away goals after a 1-0 first leg defeat and 2-1 second leg victory.
President Agnelli said he would take a few days to reflect and evaluate the situation, but it seems as if the decision was made very quickly indeed.
The 61-year-old leaves the Juve job after just 51 competitive matches, overseeing 34 victories, eight draws and nine defeats.
His team scored 100 goals and conceded 55, averaging 2.16 points per game.
Sarri spent most of his career in the amateur leagues, having joined the sport late in life after quitting his job in banking.
He shot to fame in Serie A with Empoli from 2012-15, then going on to impress with his style of Sarriball at Napoli from 2015-18, winning the Europa League trophy at Chelsea.
He had been under contract at Juventus until June 2022, but was dismissed just one season into his tenure.
They amassed 83 Serie A points this season, fewer than in any other campaigns during this nine-year winning streak, and conceded 43 goals in 38 rounds.
The Bianconeri scored 76, fewer than Atalanta, Inter, Lazio and even fifth-placed Roma.
