He told the club's website: "This club has the calibre of squad that any player would want to be part of.
"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."
