Dele Alli has signed a new contract with Tottenham Hotspur that runs until the summer of 2021.
The 19-year-old only arrived at White Hart Lane in the summer, having agreed the move 12 months ago before being immediately loaned back to the MK Dons.
Since then, the midfielder has scored five goals in 26 appearances for Spurs - form that has earned him senior international recognition from England boss Roy Hodgson.
His performances and development have now been rewarded in the shape of fresh terms, which have tied him to the North Londoners for another five years.
"I'm delighted. The club has been great to me since I've come here, we've got a great young team," he told the club's official website.
"It hasn't all been easy but everybody has helped me settle in so quickly, I can't thank them enough. I've got a lot to learn and this is a great club to do that."
Alli has been capped four times by the Three Lions, scoring one goal.
