Juventus manager Andrea Pirlo oversaw a training session of his squad minus star striker Cristiano Ronaldo as he continues to isolate after contracting Covid-19.
Ronaldo, 35, tested positive for coronavirus last Monday, a day after representing Portugal in their Uefa Nations League match against France. The Portuguese Football Federation said the player was "asymptomatic".
Italy's sports minister Vincenzo Spadafora said Ronaldo may have violated coronavirus measures by returning to Turin from Portugal last Thursday after testing positive.
While Ronaldo was a notable absence, the rest of the squad were put through their paces at their training complex in Turin, including Alvaro Morata, who scored for Juve in Saturday's 1-1 draw at Crotone in Serie A.
Juve open their Champions League campaign away to Ukraine's Dynamo Kiev on Tuesday with Barcelona and Ferencvaros making up Group G.
