Tottenham have held talks over a move for Southampton defender Jannik Vestergaard.
Spurs are in the market for defensive reinforcements this summer with Danish centre-back Vestergaard an appealing option as his contract expires next summer.
Toby Alderweireld only has has one year left on his contract and wants to leave the club this summer.
Spurs are also front-runners to sign Vestergaard's £25m-rated international teammate Joachim Andersen from Lyon.
He spent last season on loan at Fulham, catching Spurs' eye, but new manager Nuno Espirito Santo is set to make the final call on whether to sanction his signing.
