Cabaria has penned a new contract to 2022.
“I am very proud of this contract renewal and announcing it at the youth sector's Christmas party was just incredible," said Calabria.
“My history with this club is something marvellous. I remember all the Christmas parties I had here at Milan, but today will definitely stick with me. I hope to see these lads in the first team with me in a few years' time."
“We can only thank Gattuso. It'll take a bit more time to absorb all his tactical ideas, but we all listen to him and he has unique experience with this club."
