Lilli Ives Campion and Georgia Brock in England’s WXV squad

A 32-strong squad at the Rugby World Cup will create extra opportunities, but Mitchell added that Cleall needs to become more mobile and explosive to match his playing style.

“There is still that opportunity, but she is under no illusions of what is required,” he said.

“Physically the game is getting quicker and she is going to have to meet that demand.

“When you are an impact player, we can’t afford for that player to be a plodder – that player has to lift the tempo of the game.”

England travel to Canada as WXV champions, having won the inaugural tournament in New Zealand in November.

They play the United States on 29 September before matches against New Zealand and Canada on the following two weekends.

England are on a 17-match winning streak, stretching back to their defeat by New Zealand in the World Cup final in 2022.

They are top of the world rankings – more than seven points clear of second-placed New Zealand – and hot favourites to win WXV before next year’s home World Cup.

BBC Sport will show all matches in WXV1 and WXV2 on BBC iPlayer, online and on the BBC Sport mobile app.
