Watford have completed the signing of defender Younes Kaboul from Sunderland.
The 30-year-old centre-back has signed a three-year contract after the Frenchman asked to leave the Wearside club due to personal reasons.
"I'm very happy and delighted to be a part of Watford Football Club, and I'm looking forward to the season," he told watfordfc.com.
Kaboul played an integral role in helping the Black Cats avoid relegation, following last year's summer move from fellow Premier League club Tottenham.
Watford are believed to have paid around £3.5million for their newest recruit.
Kaboul said of his latest switch: "Just from outside, I can see it's a family club, there are some good players here and I'm very confident.
"The club had a very good season last year, and we need to carry that on to be even better."
