Alli joined Spurs from MK Dons in February 2015 and his new deal at White Hart Lane will run until 2022. The 20-year-old has scored 11 goals and nine assists in his 38 Premier League appearances for Mauricio Pochettino’s side.
He follows fellow first-team players Christian Eriksen, Eric Dier, Tom Carroll and Harry Winks, who have all extended their contracts in the last month.
“I’m happy to be here and playing at Tottenham,” Alli stated on the club’s Twitter account. “Personally I can’t think of anywhere better, with the fans, the manager we’ve got here and the young team. It’s a great place to be.”
