England head coach Eddie Jones says he will continue his search for the right players after naming his 33-man training squad for the three-day camp in Oxford.
The camp is ahead of the Old Mutual Wealth Series to be played in November and Jones has named two uncapped players in Marcus Smith and Tom Dunn, as well as a number of players who won their first caps on the tour to Argentina in June.
England have three Tests starting with Argentina, who Jones' side beat 2-0 in June; Australia, who have lost on the previous four occasions to England; and Samoa, who last played England in 2014.
“Tomorrow a couple of players could be injured for the season or be injured for the World Cup so you never know where you are," said Jones.
“I think in the first two years we’ve established a good base, we’ve got some credit in the bank and a base of players to build on.
“It’s about finding the 31 players that can win the World Cup for us and that is the project for the next two years and we’re about to embrace that."
He added: “Some guys need to work on their games and we’ve had those discussion with them, other guys are coming back from injuries and need some game time and we don’t think they’d benefit from being with England squad at the moment.”
England were last in action in June when they won two Tests in Argentina with a changed squad because several players were involved with the British & Irish Lions squad in New Zealand.
With the Pumas first up at Twickenham Stadium on Saturday 11 November, Jones says that fixture is where all of his concentration is at the moment.
The final England squad will be announced on 26 October to play in the Old Mutual Wealth Series. Before that, Jones' side will travel to Portugal for a week’s training camp at the end of October before final preparations begin at the Mitsubishi Motors England Rugby training centre.
“It’s all specifically about focusing on Argentina, about meeting their challenges as that’s our first game, that’s our most important game," added Jones.
“They’ve had a tough season again but like any good team they’ve got a good game in them and we’ve just got to make sure we prepare well for Argentina and then we’ll worry about the games after that.
“It’s been a tough season for them and they’re trying to find themselves and trying to find that balance between playing traditional Argentinian rugby and moving with the popular rugby at the moment, which is obviously led by New Zealand.”
'Fifth choice number 10'
Harlequins fly half Marcus Smith and Bath hooker Tom Dunn are the two uncapped players called-up to join the squad in Oxford.
18-year-old Smith made his Aviva Premiership debut in the season-opening London Double Header at Twickenham Stadium while Tom Dunn has started all of Bath's three league games so far this campaign."He’s an apprentice who has come to learn about the game."
They join Tom Curry, Nick Isiekwe, Sam Underhill, Harry Williams, Piers Francis and Alex Lozowski who are all relatively new to the England set up having won their first caps in Argentina in June.
On the inclusion of Smith, Jones joked: “He’ll clean some boots, hold some bags and I’m sure he’ll do that well.
“He’s fifth choice number 10 so I’m sure he’s going to be good at shining George Ford’s shoes. He’s an apprentice who has come to learn about the game."
