Tottenham have agreed a deal with Estudiantes for Argentina U20 defender Juan Foyth, Sky Sports News understands.
Spurs boss Mauricio Pochettino has been targeting Foyth for much of the summer although, for a while, it appeared the move was dead because of the Argentinian side's valuation of the player.
Pochettino decided to withdraw from talks after Estudiantes chief Juan Sebastian Veron - who played with Pochettino for Argentina - demanded more money for the 19-year-old.
Foyth is rated one of the most talented young defenders in world football and Spurs' move for him had also been complicated by interest from big-spending Ligue 1 side Paris Saint-Germain.
But it would appear the ball-playing defender has instead chosen to come to the Premier League after speaking with Pochettino - he would become their second summer signing after Ajax's Davinson Sanchez.
Speaking to Argentinian newspaper El Dia, Foyth is quoted as saying: "It's a club that bets on the young and I think I'm going to have a chance to play.
"I also spoke with Mauricio Pochettino and I liked what he said. It was what helped me decide that Tottenham was the right place to continue my career.
"He told me to go, train and that I would be involved I would play. He also told me what the club was like, what job idea it had."
