Eric Dier has signed a new five-year extension with Tottenham Hotspur through 2021.

Tottenham recruited Dier for £4 million from Sporting Lisbon in 2014. Following a season of playing in defence, Pochettino transformed him into the classy defensive midfielder central to his team’s progress.

“There are many reasons I wanted to commit my future to Tottenham,” said Dier. “We have a fantastic squad full of young, exciting players. We’ve got the new stadium on its way, the fantastic facilities at the training ground, and a fantastic manager who’s great for all us young players.

“He really looks after us, and makes sure we keep improving. Wembley being filled with 80,000 or more Tottenham fans is going to be an amazing experience. Playing in the Champions League there is very unique, so those two things are going to be fantastic.”
