According to a report in the Shields Gazette, Sunderland are in talks with six potential transfer targets.
David Moyes is eager to add five players to his squad, as Sunderland prepare for the new season.
Moyes wants to strengthen in every area, as he looks to add quality at the Stadium of Light.
Sunderland are the only club in the Premier League who have not made a signing so far this transfer window.
The Black Cats were close to landing Davide Santon when Sam Allardyce was in charge, but a deal fell through at the last minute.
Sunderland are now thought to be making progress, as they search for new additions, though.
The Black Cats are said to be looking at signing the likes of Adnan Januzaj, DeAndre Yedlin and Marouane Fellaini.
Sunderland’s season starts in under two weeks’ time, with a match against Manchester City.
