Transfer website Calciomercato have linked the Gunners with a summer move for the Belgium international, who made just one appearance during Euro 2016.
It is thought that Arsene Wenger is in the market for a new left-back as he considers the future of out-of-favour academy product Kieran Gibbs.
Oostende have reportedly accepted Lazio's £2.5million bid for the 21-year-old, whose contract at the Belgian club expires in a year's time.
