AC Milan have signed the USA international from Belgian side Standard Liege, the club have announced.
The 27-year-old impressed during the recent Confederations Cup for the United States, but it comes as something of a surprise that the Rossoneri have moved to snap him.
"AC Milan would like to inform that they have signed Oguchi Onyewu on a permanent basis from Standard Liege," a statement on the club's official website reads.
The contract is for three years.
Onyewu arrives on a Bosman transfer as his contract at Liege had expired. The 6' 4" centerback possesses a Belgian passport, and so will not take up Milan's final non-EU slot.
Formerly with Newcastle United, Metz, and La Louviere, he has won 47 caps for the United States, and is expected to fight it out with Thiago Silva for a place alongside Alessandro Nesta in the center of the Milan defense next season.
