Inter Milan fans are celebrating their team being crowned Italian champions after a draw between Sassuolo and Atalanta ensured they can't be caught at the top.
After second-place Atalanta drew 1-1 at Sassuolo on Sunday to guarantee Antonio Conte's side can't be caught at the top, the city of Milan erupted into a cacophony of car horns on the final whistle.
The result confirmed Inter as champions - with an insurmountable 13-point lead with four matches to spare - and fans immediately started gathering in the main square in front of the cathedral to celebrate.
Thousands of Nerazzurri fans congregated in Piazza Duomo, with flags and scarves, chanting and singing as they jumped and clapped with little heed to coronavirus restrictions.
Almost all wore masks but many were pulled down below their chins, as they also set off flares and fireworks.
It was Inter's first trophy since 2011 and their first Serie A title since 2010, when they claimed the treble of the league, Champions League and Italian Cup under Jose Mourinho.
"We are, yes, we are. Champions of Italy. We can finally scream it, after dreaming of it, after keeping it hidden in the depths of our hearts, after holding on to it like a precious dream that we did not want to waste," read a lengthy statement on the Inter website.
"We wear this Scudetto. Beautiful, emphatic, deserved. Long-awaited and yearned for.
"A team that represents an entire population, the Nerazzurri. A team that has won, that has dominated. With only one big regret: not being able to share the joys on the pitch with the Nerazzurri fans."
Fans have been banned from matches in Italy for most of the last year because of the coronavirus pandemic.
Conte's Inter have ended Juventus' grip on the league crown after the Turin giants' nine successive Serie A titles.
Inter have become the first foreign-owned team to win Serie A, with Chinese group Suning having taken over the club in 2016.
After Inter won 2-0 at Crotone on Saturday, Atalanta were the only team that could possibly catch Conte's side but they had to win to do so.
Elsewhere, two late goals from Cristiano Ronaldo saw Juventus fight back to win 2-1 at Udinese and boost their chances of qualifying for the Champions League.
Udinese had led for most of the match following Nahuel Molina's 10th-minute goal but Ronaldo levelled from the spot seven minutes from time after Rodrigo De Paul was penalised for handball, and the Juventus forward headed in the winner six minutes later.
Juventus moved level on points with second-placed Atalanta and AC Milan.
Fifth-placed Napoli are two points further back after being held to a 1-1 draw by Cagliari following a stoppage-time equaliser from the Sardinian side.
Lazio are only five points off the pace for Champions League qualification and have a game in hand after beating Genoa 4-3.
