Jermain Defoe has claimed that Younes Kaboul will prove to be a "great signing" for Sunderland.

The French defender moved to the Stadium of Light from Tottenham Hotspur yesterday on a four-year contract.

Defoe, who previously played with Kaboul at Spurs and Portsmouth, believes that the 29-year-old will bring a winning attitude to his new club.

"Younes is a winner and a natural leader on the pitch and he'll come to the club and bring that attitude – he's a great signing for us," the striker told Sunderland's official website.

"Even in training he was always going for it - running, tackling, heading, attacking. Fans will love what he'll bring to the team.

"Dick Advocaat asked me what I thought of him and I told him if you can get him he'll be a top signing. He's a great guy. Obviously I played with him at Tottenham for a few years and then again at Portsmouth. He's a top player and a top professional."

Sunderland continue their pre-season tour of North America on Saturday against Mexican side Pachuca in Sacramento.
