Stuart Lancaster has no concerns the criticism of England's scrum will influence referee Romain Poite this weekend ahead of their key Rugby World Cup pool match against Australia.

The criticism came off the back of England's defeat against Wales and the performance of the host's front-row. Former Australia coach Bob Dwyer took aim at Joe Marler saying: "The English work on having a reputation for legal scrummaging while doing the opposite. If I was [current Australia coach] Michael Cheika, I would be asking the referee: 'is that [Marler angling in] allowed?'."

And former referee Jonathan Kaplan echoed Dwyer's claims writing on his blog - RateTheRef - that against Wales referee Jerome Garces "rewarded a dominant English scrum with penalties, which on the face of it seems right".

"However, on closer inspection - and this would have been part of his preparation - it was clear that English loose-head Marler was going in on the angle. Repeatedly."

But Lancaster has no concerns over the refereeing of that specific area.

"We don't get a chance to speak to the referees but we are in constant dialogue with Joel Jutge, the man who is in charge of the referees. We've had very positive feedback from him, consistently," Lancaster said. "[England forwards coach] Graham Rowntree is regarded as one of the experts in the field - our scrum has been good and honest and excellent across the last three years.

"We've got a high-quality referee refereeing this game and he is capable of refereeing this game on his own without any other advice."

Lancaster added: "With Joe [Launchbury] coming in for Courtney [Lawes] - Courtney's 115kg, Joe's 125kg - that's an extra 10kg behind the tight-head. I hope the Australia loose-head is ready."
