"Pereyra is in Turin for Juventus medical," a statement on the club's official website reads. "The 23-year-old midfielder is currently undergoing medical tests ahead of a proposed move from Udinese.
"The young Argentine will take his first tests at the city's Clinica Fornaca di Sessant, before completing the procedure at the Istituto di Medicina dello Sport medical center."

The Argentine has since developed into an important first-team member at the Stadio Friuli, making over 100 official appearances in the past three seasons.
Juventus has already secured the services of Morata from Real Madrid, Patrice Evra from Manchester United and Kingsley Coman from Paris Saint-Germain as new head coach Massimiliano Allegri looks to bolster his squad to challenge for both domestic and European honors next season.
