Tottenham have signed Argentine centre-back Juan Foyth from Estudiantes for a reported £8m on a five-year deal.
The 19-year-old broke into the Estudiantes first team last season, making seven appearances.
He has played for Argentina under-20s and featured at the Under-20 World Cup, playing against eventual winners England in the group stages.
Spurs are also close to the signing of Ivory Coast full-back Serge Aurier, 24, from Paris St-Germain.
Foyth is Spurs’ third signing of the summer, after the arrivals of goalkeeper Paulo Gazzaniga and defender Davinson Sanchez.
