Erm, nah, de Minaur will be a massive favourite for good reason if they both get through, and I would say he could not beat anyone in the top 5 on their day no matter how well he plays. He should not be viewed as "Should" be making the semi final just because he's steam rolled three unseeded players, one of which was injured anyway.
I mean it's not impossible for him to beat de Minaur by any stretch but it'd be a great result, he's only got a handful of wins against top 10 players in his career. You give him 2 years I imagine he'll be knocking on the top 10 himself at least I'd imagine, but right now Alex de Minaur would be a very tough game and an excellent win for him and I wouldn't be betting on him to beat him.
