England coach Eddie Jones has criticised young talents in the country of not having enough hunger despite their successful 2-0 series win over Argentina in the summer tour.
Nearly 30 front line players from the squad were missing due to British and Irish Lions commitments, injuries and suspension but still England registered victories of 34-38 and 25-35 in San Juan and Santa Fe respectively.
Argentina are in the same pool as England in the 2019 World Cup and Jones, whose ultimate goal is to conquer the mega event in Japan said his team needs to improve in all attributes to stand a chance.
“The biggest thing I have learnt that to beat Argentina at the World Cup we are going to have to improve,” Jones said.
“We are not bulletproof at the moment. To win at the World Cup you need to be bulletproof.”
Sport betting is becoming more popular with the growth of the sport, especially in the host nation Japan and other Asian countries.
Jones also urged the Rugby Football Union to create a tougher path for the younger players to make it to the senior teams in order to make them work hard in every level and guard against complacency.
"I think we have got good depth but also I think the younger players are not hungry enough," the Australian was quoted as saying by British media.
"They find it too easy. They play in the under-20s, they become (Junior) World Cup champions and they get a contract straight away. That doesn't happen in any other country in the world.
"Having had this experience here will make them hungry -- England players need to be hungrier."
Earlier, Jones said he wanted to identify at least three youngsters from the tour, who could be in contention for the 2019 World Cup and the performances of Harry Williams, Charlie Ewels, Tom Curry, Sam Underhill and Mark Wilson would have definitely pleased the former Wallabies coach.
After having a one-on-one feedback with the squad members on Sunday, Jones' next task will be to announce a 45-man Elite Player Squad in August keeping in mind the World Cup 2019.
The 57-year-old had phenomenal success with the red rose team after taking over from the 2015 World Cup debacle as he helped them record a 18-match winning streak but Jones has challenged the team to take a level further leading into the 2019 edition with an ultimate goal of reaching the number one position in rankings.
“Today ends the first two years in the job, we are 21 wins, one loss,” Jones said.
“The next phase we want to go through undefeated – that is the next challenge. If we do that you go to the World Cup as No 1.”
Jones had also indicated on resting five front-line players for the November internationals that includes clashes against Argentina, Samoa and Australia.
“There is no risk in that,” Jones said.
“My job is to win the World Cup, not to win the November series 3-0, it is to win the World Cup. If I pick a good enough team we will still win 3-0 in November.
“The challenge is to build a bullet-proof team. At the World Cup you can get a team that on one day can be absolutely red hot.
"Every offload sticks, the referee gives 50-50 decisions, you have got to be good enough to beat these teams and we are not at the moment but we are moving in the right direction.”
