Juve pushed for more goals in the closing stages of the game, but they were unable to create another clear-cut chance as the encounter ended 2-0.
It was Ronaldo's fourth goal this season for Juventus, with the 33-year-old celebrating wildly with his teammates, as the Italian champions claimed their tenth consecutive win in all competitions. Mayorga went to the Las Vegas police a day later, but said she was hesitant to name Ronaldo in the accusation due to fear of his fame and influence.
But a full-page advert showing Ronaldo wearing only underpants appeared in Italy's La Gazzetta dello Sport newspaper on Saturday.
Las Vegas police confirmed they had reopened a sexual assault case from 2009 by request of the woman named in a lawsuit filed on September 27.
The back page was dominated by an advert for Ronaldo's line of underwear, featuring a full-page photograph of the player bare-chested.
The Uruguayan opened the scoring in Udine, latching on to Joao Cancelo's cross and nodding in from close range ahead of Cristiano Ronaldo.
Actually, Ronaldo's image was removed from the game's Twitter page as PC Gamer points out, although EA has denied it has anything to do with the alleged rape accusations. But his sponsors Nike and video game maker EA Sports have expressed concern about the allegation.
The Juventus and Portugal player has firmly denied these allegations, saying he had a "clear conscience". On Friday, they closed down 9.92% at €1.19 on the Milan stock exchange. "If he had stayed at Real Madrid nobody would have said a thing", said Juventus supporter Stefano Pianeta outside the stadium, referring to Ronaldo's recent transfer from Madrid.
"The events allegedly dating back to nearly 10 years ago do not change this opinion, which is shared by anyone who has come into contact with this great champion".
The defending Serie A champions' tweets were widely panned on social media as "dismissive" and "insensitive".
Mayorga's lawsuit accuses Ronaldo and his team of taking advantage of Mayorga's fragile emotional state to coerce her into signing a settlement and nondisclosure agreement in 2009.
