Gremio winger Everton will reportedly undergo a medical with Arsenal.
Fox Sports says the Gunners have sent a physician to Porto Alegre to assess the 23-year-old after Wednesday night's clash with Bahia.
The deal is reportedly worth $45million, consisting of a $31million signing fee plus $14m in add-ons.
Arsenal are also expected to seal a loan-deal for Real Madrid midfielder Dani Ceballos this week.
