Aston Villa have shown their interest in signing Arsenal goalkeeper Emiliano Martinez.
Arsenal are under no pressure to sell Martinez and only willing to sell if they can find a replacement.
The Gunners have an interest in Brentford keeper David Raya, who their goalkeeping coach Inaki Cana Pavon worked with at Brentford.
Nonetheless, Brentford insist Raya, who is under contract until 2023, is not for sale.
Martinez has two years left on his contract at the Emirates Stadium and impressed since replacing Leno when the German got injured in June.
He kept nine clean sheets in 23 games last season and helped Arsenal to win the FA Cup, also starting for their Community Shield victory on penalties over Liverpool.
