Arsenal have completed the signing of South Korea captain Park Chu-Young from Monaco, subject to a formal registration process.

The striker has penned what is thought to be an initial two-year contract, amid reports he will be forced to return home in 2013 for a period of military service.

The Gunners have signed the 26-year-old from under the noses of Lille, who were convinced they had reached an agreement for the player to join them on Saturday.
