Milan has completed the signing of Roma midfielder Andrea Bertolacci on a four-year deal.
Bertolacci caught the eye with a string of impressive performances when playing for Genoa as part of a co-ownership deal last season, the midfielder scoring six goals in 34 Serie A outings.
The Italy international was subsequently linked with Milan and he underwent a medical at the club earlier on Monday before the transfer was confirmed.
The 24-year-old, who has spoken of his delight at moving to San Siro, becomes Sinisa Mihajlovic's first major signing since he replaced Filippo Inzaghi as head coach earlier this month.
