England head coach Eddie Jones admitted disciplinary issues were inevitable at the World Cup after taking the shock decision to overlook Ben Te'o for selection.

Rugby league convert Te'o was a surprise omission from the 31-man squad destined for Japan 2019 after losing out to the heralded Piers Francis, who has been limited to five caps.

Until he was involved in a scuffle with Mike Brown during a social event at England's warm-weather camp in Treviso a fortnight ago, Te'o was considered a certainty to travel due to his status as an ever-present under Jones.

Since taking over in 2015, Jones has regularly pointed out that the World Cup is won by a highly experienced team, yet his decision to jettison the likes of Chris Robshaw, Danny Care and Brown has given England a callow look.

But the Australian hopes his players' physicality can make up for the deficit.

"I'm convinced it's our best 31. I could have picked more experienced players but I just don't feel they'll give us what the younger guys will give us," Jones said.

"I think the game's changing a lot, too... It's become such a power game. Experience is always important, but maybe we can get around it."
