Tottenham Hotspur have announced that defender Eric Dier has signed a new five-year deal with the club.
The 21-year-old, who joined Spurs from Sporting Lisbon last summer, has agreed a contract that will keep him at White Hart Lane until 2020.
The England Under-21 international, who can play as a full-back or centre-back, has largely been deployed as a holding midfielder so far this season.
"We are delighted to announce that Eric Dier has signed a new contract with the club which will run until 2020," Spurs stated on their official website.
Dier has scored three goals in 41 appearances for Spurs in all competitions.
