Southampton midfielder Pierre-Emile Hojbjerg will complete his move to Tottenham this weekend, with Kyle Walker-Petersheading the other way.
Both deals have been kept separate but fees of £15million for the Dane and £12m for the English defender have been agreed.
Hojbjerg will now discuss personal terms with Tottenham, which is expected to be a formality given the player's desire to join Jose Mourinho's team.
Mourinho has been an admirer of Hojbjerg for some months, with Spurs registering tentative interest in the 25-year-old during the January transfer window.
The Spurs boss is keen to bring in a more combative midfielder to allow his creative talents to flourish further forward, while Hojbjerg has been outspoken about his desire to play at a higher level.
