Manager Vincenzo Montella has significantly overhauled his squad after signing a new contract in May and Biglia is the latest fresh face through the door ahead of the new Serie A season.

The Argentina international has long been a target for Milan and the Rossoneri have paid a reported €17m to bring him to the club, with Biglia signing a three-year contract.

AC Milan completed a major coup with the signing of Juventus defensive lynchpin Leonardo Bonucci for €42million on Friday and Biglia becomes the 10th new arrival of the transfer window at San Siro under their new owners, Yonghong Li’s Rossoneri Sport Investment Lux group.

Andrea Conti, Andre Silva, Hakan Calhanoglu, Mateo Musacchio, Ricardo Rodriguez, Franck Kessie, Antonio Donnarumma and Fabio Borini have all completed moves to Milan, with the club’s heavy spending set to continue.
