Cristiano Ronaldo unveiled a new hairstyle as it was revealed he had once again tested positive for coronavirus.

Ronaldo is currently isolating at his home in Turin after testing positive for Covid-19 on October 13 while he was with the Portuguese national team for Nations League matches.

Sky Sport Italia and Gazzetta Dello Sport reported that Ronaldo, 35, received another positive result.

Juventus will be anxious as they prepare for next week's Champions League clash against Barcelona. The Portuguese forward now looks doubtful for Sunday's Serie A game against Hellas Verona, and the clash against great rival Lionel Messi's Barcelona on October 28.

Under UEFA rules the five-time Ballon d'Or winner needs to test negative 24 hours before the Barcelona game in Turin to be included in the squad.

Ronaldo, however, has continued training at home posting a video on social media of training in his gym, sporting a new shaved head look.

"Success in life is not measured by what you achieve, but by the obstacles you overcome," Ronaldo wrote.

On Thursday, Ronaldo posted another photo, with the caption: "Thursday style!"
