Cristiano Ronaldo is remaining in quarantine in his Madeira home after Juventus team-mate Daniele Rugani tested positive for coronavirus.
The Portuguese star flew to his homeland to visit his mother, who recently suffered a stroke, before the news broke and must stay put rather than fly back to northern Italy where the outbreak is at its most rampant, Dailymail reports.
Both Ronaldo and Rugani shared a dressing room on Sunday when Juventus beat Inter Milan 2-0 behind closed doors.
A picture posted on Instagram by Miralem Pjanic after the game show Ronaldo and Rugani celebrating the victory in a close huddle with their team-mates.
Everyone who came into contact with Rugani on both sides has now required to be in isolation.
The Portuguese press plastered the story over their front pages with Quotidiano Sportivo and Abola both running headlines about Ronaldo being in quarantine.
All sporting events in Italy have been canceled until at least April 3 but Juventus are scheduled to face Lyon in the Champions League next Tuesday.
That game is due to be played behind closed doors but is now widely expected to be postponed by UEFA.
Rugani is the second professional football to test positive, with Hannover 96 defender Timo Hubers currently in quarantine.
He took to Twitter and wrote: ‘You will have read the news and that’s why I want to reassure all those who are worrying about me, I’m fine.
‘I urge everyone to respect the rules because this virus makes no distinctions! Let’s do it for ourselves, for our loved ones and for those around us.’
