Cheika unconcerned by penalty count

Wallabies head coach Michael Cheika felt that some of the high tackle decisions from referee Mathieu Raynal were "unlucky" on his side.

Michael Hooper and Adam Coleman were both sin-binned in the first half as Australia gave away numerous penalty for high tackles.

Speaking afterwards, Cheika felt the decisions were a little harsh but was glad to see his players come though a tricky period.

“No I don't think so, I thought we were genuinely unlucky with the high tackle things," Cheika stated.

“A few arms across shoulders, and to lose two players to that. They weren't swinging and it was usually because someone had been stepped. But you've got to live with them and get on with it.

“I thought we got a little rattled during those times, but then we got it together.

The Wallabies boss was also asked about an off-the-ball incident involving replacement Nick Phipps, when he appeared to push the Argentina physio out the way.

“I think I'm not quite sure to be honest what went down," he explained.

“No one was injured. So Nick's probably trying to get the ball.

“I really don't know what was going through anyone's mind. I think the referee dealt with it on the field, as best he could."

Australia will be back at Twickenham on December 3 for a re-match with England, and Cheika hopes to see more "edge" from his players as they look for revenge over Eddie Jones and his side.

“I just want to have a bit more edge around everything," Cheika said.

“We need to start chasing what we want out of a game a little bit harder.

“I though the three-nil series the way it worked out, I thought in two of those games we had a lot of ball and didn't get the rewards. The team's been changing so much, I probably didn't realise it would change as much as it has.

“A lot of our guys have really stood up to be counted, and we're creating some competition, and that should bring a bit of edge with it."
