The 24-year-old England squad player joined the White Hart Lane outfit in 2005 from Newcastle.

He has earned 17 England caps and said he was delighted to commit his long-term future to Spurs.

"This club has the calibre of squad that any player would want to be part of," he told the Spurs website.

"The spirit in the squad is terrific, the club is ambitious and undoubtedly moving forward.

"I feel I still have a lot of potential to develop further and playing alongside team-mates of this quality will help me do that.

"I am very happy here and would love to stay at Tottenham for the rest of my career."

Manager Martin Jol added: "JJ has made a big contribution over the last two seasons and he is improving as a player all the time. His goals from midfield are a vital ingredient for us and he is already off the mark this season.

"I am delighted he has committed his future to the club because JJ has so much talent and is such a positive player.

"He always wants to learn and that is the right mentality to have, he wants to prove that he is a top player and the sky is the limit for him."
