Los Angeles-based South African Van Heerden, 29, is two fights into his comeback from losing to the talented Errol Spence in September and is on the lookout for a first opponent of 2017.
After sharing sessions with newly-licensed McGregor as the Irishman tested the boxing waters, Van Heerden is convinced he has the MMA star’s number and wants the opportunity to prove it.
“Conor is a great MMA fighter but boxing is the sweet science and in that particular class, I’m the professor to him,” Van Heerden exclusively told World Boxing News.
“I tagged him effortlessly during sparring, he knows it and I know it. There’s no way he takes a fight against me because he knows it’s lose-lose for him.
“One thing I will say is that he’s not getting near Floyd Mayweather, that’s not happening. Floyd is only fighting in Vegas, so right now, here in LA, he’s got the guy who made him look bad when boxing.
“If he’s as bad as he says he is, climb in there with me and let’s fight. We can schedule it for twelve but it’ll only go half of that.
“Conor can’t stand with me that long, he knows it and you best believe I do too,” he added.
McGregor has already been called out by ex-world champion Paulie Malignaggi this week and it seems there will soon be a queue of boxers wanting a first crack at the former two-weight UFC title holder.
