Speaking during the Channel 9 broadcast on day three when a trivia question popped up that listed Muller as one of the possible answers, Warnie addressed the infamous incident when Ian Healy reminded him he was bowling at the time the sledge was uttered.
He still maintained his innocence, but he appeared to heap an insult on Muller in the process.
"Now that you bring it up, I may as well address it. It's been about 15 years or whatever it's been, but I'm glad you've brought it up," Warne said.
"Just to let you know I was halfway down the pitch and there was an ABC independent stump mic in the cameras, in the stumps, and they didn't pick anything up, so if anyone wants to still pretend it was me, it wasn't. Just to clear that up.
"And if I wanted to tell him that, I would have told him that anyway. Whoever did say it, it's probably true."
So even if he didn't say it, that last line suggests he may well have thought it.
