Sunderland will reportedly move for Blackburn Rovers midfielder Steven N'Zonzi before the start of the season.
The 23-year-old was left behind for Rovers' pre-season tour of Austria, and it is almost certain that the Frenchman will depart the club.
The Black Cats will make an offer of around £5m, according to Sky Sports News, as they attempt to ready their squad for the new campaign.
N'Zonzi made 34 appearances for Rovers last season.
