Arsenal have agreed to loan midfielder Fabio Vieira back to Porto.
Vieira, 24, joined Arsenal from Porto in 2022 for £30m but has struggled to make an impact.
Porto want him to replace Francisco Conceicao who is an option for Juventus.
The 24-year-old won’t be in the Arsenal squad to face Aston Villa this weekend as he finalises his return to Porto.
The imminent arrival of Mikel Merino from Real Sociedad plus the continued development of 17-year-old Ethan Nwaneri means that Vieira isn’t a key part of Arsenal’s plans.
