You're not just "pointing out the difficulties of proof" though, we've all read your comments.
You said Mbappé was lying when he said he heard it. What's that got to do with pointing out the difficulties of proof?
Then you claimed they don't speak the same language, despite all 3 speaking fluent Spanish. Again, What's that got to do with pointing out the difficulties of proof?
Then you started throwing out insane counterfactuals like "Maybe he just called him a ****". That's nothing to do with pointing out the difficulties of proof.
@Superace is right. From the moment the incident has happened you've tried to twist absolutely everything that's come out to discredit the Real Madrid players and make excuses for Prestianni.
