England face Tonga in their World Cup opener on Sunday amid a call from within their own camp to play a Test in the Pacific nation to aid a region that has enriched to the sport.

Attack coach Scott Wisemantel believes that Twickenham should not view a tour match against the impoverished Islanders – whose population numbers a mere 108,000 – as beneath them.

For the past two years Wisemantel has overseen the Pacific Combine – a programme that identifies talent in Tonga, Fiji and Samoa with the ambition of securing their emerging stars professional contracts.

"You speak to a Tongan and you talk about the country and you say 'so you're from Tonga'.

"Occasionally they'll say 'I'm from the Kingdom of Tonga' and there's a reason for it. They're quite fierce in that regard."

England's low key camp in Miyazaki ends on Wednesday when they will head to Sapporo with Jones naming his team the following day.

Only wing Jack Nowell and prop Mako Vunipola are definitively unavailable for selection.
