Australia head coach Michael Cheika has resumed his war of words with Eddie Jones, claiming his England counterpart has "always operated with a chip on his shoulder".
The two have been involved in several back-and-forths in the media during the build-up to Saturday's Test at Twickenham.
Jones accused the Australian press of being disrespectful towards him and his England team during June's series Down Under, which led to Cheika stating that Jones is risking damaging his legacy in his home country.
Cheika, a former team-mate of Jones at Sydney-based side Randwick, says his rival will always be respected for taking Australia to the 2003 Rugby World Cup final - where they were beaten by England - but believes Jones is always looking for a way to create a siege mentality.
"I don't know where that [disrespect in Australia] comes from. He is very respected in Australia," he said.
"He is a good Australian coach who took Australia to a World Cup final when we didn't expect to go fantastic.
"He is respected for that. He certainly is by me as a former team-mate of his, and you saw when he was in Australia that he got a lot of respect.
"He has always operated with a chip on his shoulder and now there isn't a chip because things are going really well, he keeps looking for it."
England have won 13 consecutive Test matches, 12 of those overseen by Jones, and victory on Saturday would equal their best winning run.
