The New Zealander questioned Whyte’s mental strength at the final press conference as he accused the British heavyweight of trying to disguise his doubts with scathing pre-fight statements.
But the Brixton man believes it was Parker’s trainer Kevin Barry who was already raising concerns about their preparations.
Whyte told Sky Sports: “What have I said about him, apart from facts that he didn’t show enough courage in the Anthony Joshua fight, that’s all I said.
“Him, Kevin Barry, they just talk rubbish. They are already making excuses.
“‘Oh Parker flew to England, flew to America’. He didn’t have to fly to America. He could have stayed and trained in England, but he decided to go back to Vegas. That’s his choice.
“‘Oh we’ve only had a six-week training camp’. No, we’ve had the same time, we’ve both had seven weeks’ training camp.
“They’re making all these excuses so when he loses, they’ll say ‘oh well, he had a hard time, jetlagged, he was this, he was that’.
“All I’m hearing is excuses, excuses. I haven’t got time for that, I’m just here to go and put that smack down on someone.”
Parker has warned Whyte to brace himself for a barrage of punches, but ‘The Body Snatcher’ doubts whether he will stand and trade, and is ready to hunt down the Kiwi if he boxes on the back foot.
“Many people say this,” said Whyte. “When they come and they feel the steel hand to hand, then they change their mind very quickly, so we’ll see.
“People forget, I’m rangy and I can box. I just choose to fight.
“The ring is only 20 by 20 [feet], so he can only run so much. He’s going to have to stop at some point.”
