Sunderland are more likely to move for Youssouf Sabaly from Paris Saint Germain.
Sunderland are desperate to add a new right-back this summer, and Sam Allardyce has made it his number one priority.
The Black Cats are currently short of options who can play on the right hand side of their defence, with Billy Jones the only member of their senior squad who can play there.
Jones struggled at Sunderland last season, and Allardyce wants to sign a player who will go straight into his first-team for next season.
The North East side are said to have a number of targets, with Debuchy one of the names being discussed.
Sunderland have also considered bringing back DeAndre Yedlin, who spent last term on loan at the Stadium of Light from Tottenham Hotspur.
It is PSG defender Youssouf Sabaly who looks the most likely addition for the Wearsiders, though.
Sabaly could reportedly join Sunderland on an initial loan, with the option to make the deal permanent for £5 million at the end of the season.
