Juventus have revealed coach Maurizio Sarri has been diagnosed with pneumonia.
The Italian tactician, who left Chelsea in June to take charge of the Bianconeri, had been struggling with flu.
The 60-year-old was taken ill last week and was treated by the club's medical staff in a bid to aid his recovery.
However, Sarri missed numerous training sessions and was not in the dugout for Juve's 1-0 friendly victory over Triestina on Saturday.
The Serie A club have now confirmed Sarri had been diagnosed with the illness after further tests and is receiving treatment.
“Maurizio Sarri, after having observed rest over the weekend, was at the JTC [medical centre] today where he coordinated the work of his staff,” a club statement read.
“Unfortunately, he could not conduct the training on the field due to the persistence of his flu, which struck him over the course of last week.
“In the late afternoon, he underwent further tests that confirmed he has pneumonia, for which specific therapy has been prescribed.
“The coach has authorised the club to communicate his state of health.”
The state of Sarri's condition has not been released but it remains to be seen whether he will miss the opening fixture of the season against Parma on Saturday.
