Tottenham Hotspur have completed the signing of defender Eric Dier from Sporting Lisbon on a five-year deal, for an undisclosed fee believed to be around £4m.
The 20-year-old Englishman progressed through the Portuguese club's academy, as his parents moved to Iberia when he was a child.
"It has always been my ambition and my dream to come back to England and play in the Premier League," Dier told the club's official website.
"I've watched a lot of Tottenham and I've always enjoyed the way they play, their attacking football. I think, coming from Portugal, that suits me and this season I just want to adapt really quickly to the Premier League and do the best I can."
Dier made 30 appearances for the Lisbon club, and spent time on loan at Everton in 2011.
