The war of words between Michael Cheika and Eddie Jones has deepened further with the Australia coach criticising England's tactics at scrums.
Jones had highlighted concerns with how Australia approached scrummaging after Saturday's 27-14 win over Argentina.
A clash with the Wallabies at Twickenham will round off England's 2016 campaign, which could see Jones' men go without a defeat in the calendar year.
Cheika and Jones butted heads when England secured a 3-0 series win over Australia earlier this year and the bad blood between them has surfaced again on this issue.
"We scrum square," Cheika said. "It will be up to the referee as to who he believes; if he wants to be influenced by the other chap that we are the ones scrumming illegally when they are the guys who had the penalty try and the yellow card against them, then it is really up to him.
"He [Jones] wants to talk about our scrum because we're cheating in the scrum, I think an important thing to note is he's got to look at his own players."
Cheika was quick to point out exactly which player he had in mind - England prop Dan Cole, who was sin-binned against Argentina and was the centre of much controversy earlier in the year.
"They are the ones who got a penalty try against them and a prop with a yellow card," Cheika explained.
"That same prop has been infringing the law since his career started probably, if not all of this year.
"If he thinks the refs are that naive that if he has a go at our scrum, they'll forget about his guy, that's up to the ref."
Cheika also believes that Jones' reputation in his native Australia could be tarnished by his continuing feud with the Wallabies coach.
"There was a lot of vitriol about Australia -- his home nation where he coached and where his opportunities were given to him to coach and grow up as a coach and play," he said.
"Personally, if you're looking to leave a legacy somewhere, you don't want to hit back at it, do you?"
