Sunderland have signed Blondy Nna Noukeu after the former Stoke City goalkeeper impressed on trial with the Championship club.
The 22-year-old, who has been training with Sunderland during the summer, has agreed a two-year deal with an option for a further year.
Noukeu was born in Cameroon and grew up in Belgium, playing youth football for Royal Excel Mouscron, before making the move to Stoke in 2019.
He never made a first team appearance for the Potters and has had loan spells with Crawley and Southend.
"This is the right place for me to be if I want to take my career to the next level," he told the club website.
