Juventus' France World Cup winner Blaise Matuidi and Hellas Verona's Mattia Zaccagni have both tested positive for coronavirus, their Serie A clubs confirmed Tuesday.

"Matuidi has undergone medical tests that have revealed his positivity to the COVID-19," the Italian champions said in a statement.

Juve added 32-year-old Matuidi is asymptomatic and currently "in voluntary home isolation." The midfielder's club teammate Daniele Rugani was the first top-flight footballer to be diagnosed with coronavirus on March 11, sending the entire team into quarantine.

In total, 13 Serie A players have officially been diagnosed with the illness including seven from Sampdoria and three at Fiorentina.

Italian midfielder Zaccagni, 24, had already been in self-isolation as a precautionary measure after Verona played Sampdoria on March 8.

"Zaccagni is doing well, in recent days, he has only had a few bouts of fever," the eighth-placed Serie A club said.

"The player, as well as the whole team, will extend their voluntary isolation at home ­until March 25, while continuing to be monitored."

Matuidi had urged his fans to "take care" in a post on Instagram at the weekend.

"At the beginning, I didn't really realize how serious this disease was and the danger," he said.

"In this difficult time for all of us, I just wanted to invite you to follow the official recommendations carefully and to take great care of yourself and your loved ones."
