It appears that Foyth will become the third south American to sign this summer for Spurs, following new club-record signing Davinson Sanchez and goalkeeper Paulo Gazzaniga. Foyth, however, reportedly wasn't happy with his prospects for breaking through in Paris and pushed for a move to Spurs.
Meanwhile, Kevin Wimmer is set to have a medical at Stoke City on Monday ahead of a £15m move from Tottenham.
But it seems Tottenham have won the race for Foyth after he received encouragement from Pochettino.
Spurs targeted 19-year-old Foyth in June, but their interest cooled after Estudiantes president Juan Sebastian Veron - a former worldwide teammate of Pochettino - upped the asking price following interest from Paris Saint-Germain.
Now, Foyth has discussed his imminent move, telling El Dia that he has made a decision to join Tottenham as they are a club who give opportunities to young players, such as Eric Dier, Dele Alli, Kyle Walker-Peters, Harry Winks and Harry Kane in recent years.
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".
Mauricio Pochettino's side have now dropped five points in two home Premier League matches this season. It's what helped me decide that Tottenham was the right place to continue my career. "He also told me what the club is like".
