The veteran fullback has completed his move and it's been confirmed he will wear the No15 shirt with the Nerazzurri.
Young declared: "It was a beautiful day today for me, thanks for the welcome.
"It's a fantastic feeling, I'm happy to be part of this Nerazzurri family."
Young becomes the first Englishman to play for Inter since former United star Paul Ince.
He added: "Paul Ince? He was an extraordinary player, a legend. I would be happy if I could follow in his footsteps. My message for the fans is that we will win again, I am here for this and I want to help the team achieve its goals.
"There are all the conditions for doing well, we hope to make the fans happy."
