The 29-year-old centre back was named Mauricio Pochettino's Tottenham captain at the start of last season, but on Thursday moved to the Stadium of Light.
Tottenham club captain Younes Kaboul has signed for Sunderland after six years at White Hart Lane, and he was quick to emphasise to the club's website how delighted he was to sign a four-year deal at the North East club.
Interest from the Black Cats has only appeared fairly recently, with Dick Advocaat chasing Belgian defender Nicolas Lombaerts for much of this week until a deal fell down at the last minute, as mentioned by the Guardian.
The Wearside club quickly turned to Kaboul, who was out of favour under Mauricio Pochettino for much of last season despite being appointed skipper at the beginning of his reign.
"I'm delighted to join Sunderland, everything went very quick but I'm very happy to be here," Kaboul told the Black Cats website. "I can't wait to meet up with my teammates and kick on."
After 141 appearances at White Hart Lane across two spells, Kaboul was perhaps a victim of Pochettino's high pressing system. He failed to feature in the Premier League after a 3-0 loss to Stoke in Novemeber, despite starting the first 11 games of the season.
"It was a little bit hard to leave," he admitted regarding his Spurs departure. "I had some good times and bad times at Spurs, but overall I keep a very good memory. But now it's behind and I'm looking forward to starting a new challenge.
"I can't wait to [play in front of the Sunderland fans]. Everytime we've played here we knew what we were going to get. The atmosphere is unbelievable."
History will reveal that Kaboul was involved in what has been a period of impressive Spurs Premier League finishes, and he famously set up the Peter Crouch goal against Manchester City that secured Champions League football. A late winner away to Arsenal was another highlight.
There is little doubt that the 29-year-old has something to offer in the Premier League if he can get some consistent game time under his belt, and with his powerful defending style, and leadership, Kaboul will surely be a vital player at the back for Sunderland next year.
