Sunderland have been put on red alert by the news Rennes star Cheikh M’Bengue wants to leave France.
The left-back has been playing in Ligue 1 for just under a decade, but he is hungry for a new challenge.
The Senegal international’s contract with Rennes expires at the end of June and he is refusing to sign an extension.
That means M’Bengue will be available for free and, according to L’Equipe, that has sparked interest from Sunderland.
The Premier League club have been scouting the 27-year-old for a year and they are now in a position to make their move.
As well as interest from Sunderland, M’Bengue has offers from clubs in Germany and Turkey.
