Spurs are close to a £4m deal for Sporting Lisbon’s England Under-21 centre-half, Eric Dier.
Mauricio Pochettino wants the 20-year-old to fire competition in central defence and provide cover at right-back and in defensive midfield.
Dier was born in Cheltenham but emigrated to Portugal at seven and he has been with Sporting since the age of eight. He spent six months on loan at Everton’s academy in 2011.
He has made 30 appearances for Sporting, impressing with his toughness and composure.
