England coped without Ashton at Twickenham on Saturday, with Charlie Sharples scoring two tries in an emphatic win – and Catt revealed Red Rose head coach Stuart Lancaster may stick with the same starting line-up.
“The guys are on top of their games and to be honest it’s about making sure what is the best team for us to beat Australia this weekend,” Catt told Sky Sports News.

“He [Ashton] doesn’t have to come in. He’s got a lot of credit for the way he has played. Hopefully he has learnt his lesson and won’t do the things he has done which put him in a spot in the first place.
