Defender Riccardo Calafiori is set to have his medical with Arsenal as his move from Bologna edges closer.
The Gunners intend for the Italy international, 22, to join the squad for their pre-season tour of the United States.
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 31 July.
Calafiori scored two goals and registered five assists in 30 Serie A appearances last season, helping Bologna claim a fifth-placed finish and a spot in next season's Champions League.
