Cristiano Ronaldo could have violated Italian coronavirus measures by returning to Turin from Portugal after testing positive, Italy's sports minister Vincenzo Spadafora said Thursday.
Spadafora said this to Radio Uno when asked whether the 35-year old Portuguese star's return had breached Covid-19 rules.
Ronaldo left the Portuguese team camp near Lisbon Wednesday to fly back to Northern Italy on his private jet.
The five-time Ballon d'Or winner was "asymptomatic" after testing positive Monday, the day after Portugal drew 0-0 with France in Paris.
However, the incident renewed controversy over his departure from Turin the previous week, which local health authorities said breached virus protocols after two Juventus staff members tested positive.
The entire Juve team were back in isolation Wednesday evening after US midfielder Weston McKennie tested positive.
Both McKennie and Ronaldo are in quarantine, for at least 10 days, and must test negative before rejoining their teammates.
Under Uefa rules a player must provide evidence that he is no longer sick a week before a European match.
Ronaldo, who will miss Juve's Champions League opener against Dynamo Kiev Tuesday, must test negative the following day to play against Barcelona a week later.
Spadafora rejected a call from the Italian regions to open stadiums to 25% capacity from the current maximum of 1,000.
