Skysports.com understands Pascal Chimbonda is currently undergoing a medical at Sunderland ahead of signing a four-year deal.
The Tottenham defender has been impressed with Black Cats boss Roy Keane, who has convinced him to quit the capital for the North East.
Sunderland have had a £23million offer accepted by Spurs for four of their players, with Keane eager to bring in Chimbonda, Teemu Tainio, Younes Kaboul and Steed Malbranque.
Keane engaged in talks with all four players at the weekend and is confident the quartet will make the move north.
Chimbonda is the first to commit to a deal, with the French international expected to tie up the move within the next 48 hours.
Everton and Aston Villa have also been linked with the former Wigan right-back but it is Sunderland who have stolen a march on their Premier League rivals.
