United may face competition in their bid to sign of Dimarco, who joined Inter's youth academy as a child and rose through the ranks.
He spent loan spells at Ascoli and Empoli before joining Swiss side Sion on a permanent deal. That move lasted just one year, however, as Inter brought him back and again loaned him out to Parma and Hellas Verona.
He has been a first-team regular for Inter since the 2021-22 campaign, however, and his performances have caught the attention of other clubs, with Real Madrid and Napoli keeping an eye on him.
