Inter Milan have won their first Serie A title in 11 years after second-placed Atalanta drew with Sassuolo.
The Milan giants are 13 points clear after Saturday’s win at Crotone with four games to go.
Inter finished second to Juventus by a point last season, but Antonio Conte has ended Juve’s run of nine straight titles in his second season in charge.
It is Inter’s first Scudetto since Jose Mourinho won both Serie A and the Champions League in 2010.
The title is Conte’s fourth Serie A title, after winning the league in three consecutive seasons during his spell as manager of Juventus between 2011 and 2014.
He also won the Premier League in his first season at Chelsea in 2017.
“This is one of the most important successes of my career,” the 51-year-old told Italian television station Rai.
“Deciding to join Inter was not easy, just when the team was not equipped to win immediately.
“Furthermore, the opponent was Juventus for whom I had worked for a long time, who had dominated for nine years. Today we can say that our sacrifices have paid off.”
But Conte would not be drawn on his future, with his contract set to expire in 12 months’ time.
“At the end of the season we will make the appropriate evaluation,” he said. “We have done something extraordinary and I want to enjoy this moment.
When Inter drew 0-0 at Udinese in January, they were two points behind city rivals AC Milan at the halfway point of the season.
Following that result, they won 11 straight games and cemented their position at the top, comfortably clear of a clutch of other clubs including Conte’s old side Juventus, who were looking for their 10th consecutive title.
With four games to go, they have already matched the number of points (82) that Mourinho needed to win the title in 2010.
Inter’s success has been built on a solid defence with Conte’s favoured 3-5-2 formation leading to just 29 goals conceded in 34 games.
At the top of the pitch, Romelu Lukaku has continued his electric form from last season and his formidable partnership with Lautaro Martinez has delivered 36 league goals so far.
Last summer, Conte splashed £36m on the lightning-quick Achraf Hakimi from Real Madrid and he has chipped in with seven goals and seven assists from right wing-back.
Conte also raided the Premier League for faded superstars Alexis Sanchez and Christian Eriksen, the latter making his mark recently with crucial goals against Napoli and Crotone.
Famously relentless, Conte has got the small details right this season and capitalised on a Juventus team in transition and flaky form from Napoli, AC Milan and Roma.
Indeed, when the former Juventus captain and manager returns to Turin for the penultimate game of the season, it will be as a title winner who has brought glory back to the San Siro – and denied Juve that record 10th successive title.
It is now up to the Old Lady and the rest of Serie A to work out how to stop Conte establishing a new dynasty in this half of Milan.
