This is terrible for Ronaldo & the Club. I see the chances of him surviving this as very slim.
Its not a question of whether there is enough evidence that meets the standards of a criminal case in the US. Its almost impossible to have evidence from a night that happened a decade ago and to pass the high standard that would get him to go to prison even if he did do it. Ronaldo is probably not going to prison.
The real question is, is there enough evidence to make a compelling claim that the rape likely happened in the court of public opinion?
An extreme example would have been bill cosby when so many women came out against him. That was enough to get public opinion to believe he did those things and that was before actual evidence and any court hearings happened. Cosby is an extreme case (because of the sheer number of women coming forward) but if these docs are legit, or people widely believe them to be legit, that will be enough for Nike & other sponsors to pull out of the sponsorship deal to protect their own image. I imagine Juve would follow suit. All it takes is for one big sponsor to pull out > the rest will follow > Ronaldo will be finished, regardless of whether the evidence is enough for a court case or not.
Think the case of Bret Kavanaugh. He got the job because of Trump/Republicans powering through despite public opinion and the allegations. They were ready to take the backlash for it in exchange of having a new supreme court judge assigned. Nike and corporate sponsors are unlikely to do something similar. These are companies with a progressive image to maintain.
