John Mitchell has instructed England to continue playing on the edge despite the disciplinary issues that have marred their Guinness Women’s Six Nations.

The Red Roses have been shown two red cards in three matches, with number eight Sarah Beckett dismissed in the opener against Italy and hooker Amy Cokayne sent off against Scotland.

Both opponents were crushed despite England being reduced to 14 players as they continue their march to a sixth successive Championship title with the visit of Ireland to Twickenham on Saturday.

While Mitchell wants technique to be refined where needed, he views his team’s physicality as an important weapon.

“I want us to continue to play on the edge, but I also want us to be aware around how we need to change our behaviour,” the Red Roses head coach said.

“In Amy’s incident, she needs to get her head under the ball. Obviously that’s something you put the ownership on the individual to change.

“We probably let the pressure off on Scotland. There were a number of times when we had the foot on their throats. We’d rather that turn into attack for us.

“There’s some good things we’ve learned from it, but we’re certainly not going to go away from being on the edge. It’s what drives us. It’s what the game’s all about and we want to defence into points.”

Beckett received a three-match ban for a dangerous clearout while Cokayne’s two yellow cards for a dangerous clearout and dangerous tackle resulted in a one-game suspension.

Both players will be available for the probable Grand Slam decider against France on Saturday week.

England had rehearsed for the eventuality of losing their number eight and hooker in the build up to each game after defence coach Sarah Hunter had presented them as scenarios in training.

“We’ve told Sarah Hunter not to give us any more scenarios!” captain Marlie Packer joked.

“So she might have said at the beginning of the Six Nations ‘eight go off the pitch’. That might have happened.

“And then last week ‘hooker you’ve got a card, go off’. And that might have happened in a game. So we’ve kind of told Sarah not to do that any more!”

Marlie Packer will lead England against Ireland on Saturday

Almost 50,000 are expected at Twickenham on Saturday and in anticipation of the atmosphere, England have adapted training at their Surrey base.

“Early on in the week, when we do more low-key training in the barn inside, we can put crowd noise in. I personally loved it,” he said.

“It paints a different picture for us. It’s been a new thing that we’ve brought in this week which has raised our game. Hopefully we can put it out on the pitch on Saturday.”

Packer has been restored at openside for the visit of Ireland, forcing Zoe Aldcroft to move from back row to lock, while Lark Atkin-Davies replaces the suspended Cokayne at hooker.
