"I travelled to meet (Roy) Keane on Saturday at Sunderland's training ground. I was extremely impressed with what he had to say," said Chimbonda.
French international full-back Chimbonda joined Wigan for £500,000 in 2005 from French club Bastia.
Chimbonda added: "Keane's honesty and openness really were fantastic and I particularly like the plans he has for Sunderland. The opportunity excites me and I hope he was impressed with what I had to say."
Three other Spurs players are also being targeted by the Black Cats.
It is understood that Steed Malbranque, Younes Kaboul and Teemu Tainio are due in the north-east for talks.
