AC Milan won their 19th Serie A title but the first for 11 years by cruising to victory at Sassuolo.
Olivier Giroud scored twice with Franck Kessie also on target for the visitors.
The title triumph vindicates Milan’s decision to appoint Stefano Pioli as manager in 2019 – a move that was initially unpopular with Pioli having led city rivals Inter for six months.
