Juventus ace Cristiano Ronaldo is set to miss their Champions League clash with Barcelona.

While showing no symptoms, Ronaldo is being forced to isolate by authorities after testing positive for coronavirus.

The UEFA protocol calls for a player to be covid-negative for at least seven days before he can be allowed to play in a Champions League or Europa League match.

Considering Ronaldo tested positive on October 13 and Juve’s Barcelona clash is set for October 28, it’s going to be extremely difficult for him to recover in time.

“Participants from Group 1 or Group 2 who have verified confirmation that they have now recovered from the virus are invited to submit documentation of this to the UPAP, including the date of diagnosis of the virus, complete relevant medical history and any other medical documents in this context e.g. SARS-CoV-2-RNA test or any other laboratory tests,” reads the protocol published by UEFA.

“This must be provided at least one week before the team’s next UEFA Match.”
