Denis Zakaria has arrived at Juventus's private clinic J Medical to undergo a medical ahead of his surprise loan move to Chelsea.
Sportsmail understands Chelsea have an option to buy the midfielder, 25, for £30million once his loan spell ends.
After failing in efforts to sign Edson Alvarez from Ajax and Ibrahim Sangare from PSV Eindhoven, Chelsea have turned to the 6ft 3ins Swiss international, who moved to Juventus in January for £4m after leaving Borussia Monchengladbach.
He had been recommended to Manchester United by Ralf Rangnick, and was under consideration at Newcastle in recent weeks, but now Chelsea have stepped in to discuss a potential loan.
