Milan chief Adriano Galliani welcomed Alessio Romagnoli to the club after sealing his move to San Siro.
Milan has completed the signing of defender Alessio Romagnoli from Roma on a five-year deal for an undisclosed fee.
Reports of a switch for the Italy under-21 center back gathered pace over the weekend before chief executive Adriano Galliani confirmed the deal was all but done on Sunday.
Romagnoli passed his medical on Tuesday and will now be reunited with coach Sinisa Mihajlovic, who signed the 20-year-old on loan while in charge of Sampdoria last season.
"Welcome Alessio, you signed with us until June 2020 and we're very happy for it," Galliani said in a statement.
