Tottenham may have snapped up their first two signings of the summer last week by landing goalkeeper Paulo Gazzaniga and defender Davinson Sanchez, but manager Pochettino is keen on more new faces.
With Kevin Wimmer set to join Stoke City and Cameron Carter-Vickers loaned out to Sheffield United, another young defender could be on the verge of arriving in North London.
Sky Sports report that Tottenham have agreed a deal to sign Estudiantes defender Juan Foyth after a lengthy pursuit, winning the race for his signature ahead of other European clubs.
The 19-year-old defender has impressed in his native Argentina, coming up through the ranks with hometown club Estudiantes, whilst he also featured for Argentina at the Under-20 World Cup in South Korea.
With Pochettino no doubt aware of the top young talents in his homeland, and Foyth now appears to be on the verge of joining Tottenham, where he can learn behind the likes of Jan Vertonghen and Toby Alderweireld.
Now, Foyth has discussed his imminent move, telling El Dia that he has decided 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.
Foyth admitted that he spoke to Pochettino about the move, and he told him that he would be given a chance in the first team if he trains hard, whilst also explaining just what Tottenham are like as a club.
"It's a club that bets on the young and I think I'm going to have a chance to play," said Foyth. "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 idea it had," he added.
