Foyth, 22, is one of the best prospects of Argentine football despite struggling for game time at Spurs.
Scouts from Villarreal have been following Foyth since his time at Estudiantes and remain high on him.
Unai Emery intends to strengthen Villarreal’s right-back position and sees Foyth as the perfect fit.
The main obstacle for Villarreal is the fact Spurs are reluctant to let Foyth leave on a permanent deal.
However, Jose Mourinho does not seem to count on Foyth, which could open the door for Villarreal.
