Nottingham Forest midfielder Morgan Gibbs-White is set to undergo a medical at Tottenham on Friday before completing a £60m move.
Well-placed sources have told BBC Sport the 25-year-old has a £60m release clause, which Spurs are set to trigger with the formalities of his switch to accelerate in the next 24 hours.
Gibbs-White, who has four England caps, was on Manchester City's radar this summer but Pep Guardiola's side have cooled their interest.
He scored seven goals and added eight assists in 34 Premier League games last season, and has attracted interest from a number of England's top clubs in recent months, but Spurs have stepped up their efforts to sign him.
