Arsenal has accepted a £16m offer from Aston Villa for goalkeeper Emiliano Martinez.
The fee could rise to £20m with add-ons, with the 28-year-old Argentinian due to undergo a medical at Villa Park this weekend and discuss personal terms.
Martinez has two years remaining on his contract at the Emirates and impressed when stepping in for Leno when the German was injured in June.
Martinez was keen to move after Arsenal manager Mikel Arteta underlined that Bernd Leno would be his first choice and that he was not keen to rotate keepers through the cup competitions.
Villa wants Martinez to start as Tom Heaton is still battling back from his knee injury. Brighton was unable to give similar promises with Mat Ryan their current number one.
He kept nine clean sheets in 23 games last season and helped Arsenal win the FA Cup, also starting their Community Shield triumph over Liverpool at the start of 2020/21.
