Conor Gallagher is set to fly to England this morning ahead of a medical with Tottenham later today - and will sign a five-and-a-half-year deal.
The 25-year-old midfielder is poised to complete a £34.7million move to Spurs from Atletico Madrid although he is yet to agree to the formality of personal terms.
Tottenham stole a march on Aston Villa, who had proposed a loan with an obligation to buy.
Gallagher's camp are keen to have the deal done before Atletico's Copa del Rey last-16 clash at Deportivo La Coruna on Tuesday evening.
