Riccardo Calafiori is set to have his medical with Arsenal as the defender’s move from Bologna is agreed in principle.
The Gunners intend for the 22-year-old to join the squad for their US pre-season tour.
Arsenal are in Los Angeles for Wednesday's match against Bournemouth and face Manchester United on Saturday. They then head to Philadelphia to play Liverpool on July 31.
The deal for the versatile Italian defender, who can play at centre back or left back, is believed to be worth around £42million.
Calafiori will be the first addition to Arteta’s squad this summer.
