Tom Wood has said that England need to show the same aggression that toppled New Zealand when they come up against Australia at Twickenham this afternoon.
Stuart Lancaster's men were dominant in a 38-21 win over the All Blacks last December, and the Northampton flanker wants to see the same attitude against the Wallabies.
"I don't know how controlled it was against New Zealand, but yes there was an element of violence. That's the game," PA quotes him as saying.
"Mentally you have got to make sure you are there. If you want to hit a ruck as hard as you can, you will hit a ruck as hard as you can if you are there fully charged up before the game, ready to go.
"Hitting a ruck is not a science. You put your head where it hurts and do it as hard and fast as you can and that is the end of it. Test his will. It's your will against his. If he's up for it more than you, if he's braver than you, he's going to get the better of you. It doesn't matter how big and strong he is. That's what breakdown is about for me."
Wood has made 14 appearances for England since making his debut against Wales in Cardiff in 2011.
