Juventus are waiting on a Covid-19 test result to see if Cristiano Ronaldo will be available for their Champions League match against Barcelona on Wednesday.
Ronaldo, 35, has been self-isolating since testing positive for the virus on 13 October and recorded another positive result last week.
Juve boss Andrea Pirlo said they would have a definitive result on Tuesday evening.
Ronaldo last played in Portugal’s 0-0 draw with France on 11 October.
Juventus will definitely be without defenders Giorgio Chiellini and Matthijs de Ligt, while Leonardo Bonucci and Paulo Dybala will both be assessed for the game in Turin.

Their opponents Barcelona are set to be without midfielder Philippe Coutinho, after the ex-Liverpool player injured his left hamstring in Saturday’s 3-1 El Clasico defeat against Real Madrid.
The length of the 28-year-old’s absence will “depend on how the injury evolves”, according to Barca.
