Alessio Romagnoli has signed a new four-year contract with AC Milan.
The Italy international has become a key man at San Siro, lining up alongside Leonardo Bonucci and making 28 Serie A appearances for Gennaro Gattuso's men last season.
And Romagnoli has now renewed his Milan deal, committing his future to the club until 2022.
A Milan statement described the contract as a "priority" for chiefs Marco Fassone and Massimiliano Mirabelli.
"I thank Fassone and Mirabelli," Romagnoli said in an announcement on Milan's Facebook page. "We hope it will be a renewal that brings us great satisfaction, both next season and also in the years to come.
