Cristiano Ronaldo has tested positive again for coronavirus on the eve of Juventus's Champions League clash against his great rival Lionel Messi's Barcelona, according to media reports in Italy and Portugal.
Portuguese TVI reported that Ronaldo "has once against tested positive for Covid-19" following a swab carried out by Juventus.
The 35-year-old is now awaiting the result of a UEFA test which, if also positive, would rule him out of the Group G game in Turin.
Ronaldo first tested positive for Covid-19 two weeks ago while playing with Portugal, and has been in self-isolation since returning to Italy.
According to TV1, the five-time Ballon d'Or winner has tested positive 18 times.
Ronaldo needed to return a negative test, 24 hours before the game to be allowed to play, according to UEFA rules.
Juventus only confirm if a player has recovered, with Sky Sport Italia and Gazzetta Dello Sport reporting that Ronaldo will miss the Barcelona game.
"Ronaldo had a test like everyone else, this evening (Tuesday) we will have the definitive result," coach Andrea Pirlo told a press conference earlier Tuesday.
"For now it's all on the high seas, when the final result comes everything will be clearer.
"Depending on the result, we'll see what we do. It's not easy to play an entire game after 15 days of inactivity."
Ronaldo, who has no symptoms, has missed three games including his side's 2-0 Champions League win at Dynamo Kiev last week.
The clash would be the first between Ronaldo and Messi since the Portugal forward left Real Madrid for Juventus in 2018.
