There was no discussion about Sinner here (negatively that is, for I had hailed Sinner's game in a comment earlier) until you shoved him here in a way that's condescending, typical of an Italian Sinner fan.
The younger, still more accomplished Alcaraz with more upside to his game, who is 3-0 against Sinner and the reigning Channel Slam champion, likely will have the better career but unlike Sinner fans, I can't say anything for sure.
There's no allusion here. Alcaraz could do with some clostebol and become the beast that's Sinner 2.0.
