Eddie Jones says England’s depth is good after they claimed a 2-0 series win over Argentina – but the head coach still wants more from his players.

For the two-Test series in South America, England fielded an inexperienced squad, including Cumbrian Mark Wilson.

Jones handed flanker Wilson, who was born in Kendal but began his rugby career in Penrith, his international debut in England’s opening 38-34 win over the Pumas in San Juan.

Cumbria’s Newcastle Falcons man Wilson was then dropped to the bench for the second test, although he again featured in a more routine 35-25 success in Santa Fe last Saturday.

And, while satisfied with the depth within his squad, Jones is calling on England’s players to become even hungrier if they are to win the 2019 World Cup.

“Having 30 players out tests your depth,” Jones said. “The depth is good but at the World Cup you don’t necessarily need your depth all the time.

“To me, it is a great lesson for us that we have to improve and improve rapidly. I think the younger players are not hungry enough.

“I think having had this experience here will make them hungry. I think England players need to be hungrier because they find it too easy.

“They play in the Under-20s, they become World Cup champions, they get a contract straight away. That doesn’t happen in any other country in the world.”

Although happy to achieve his aim of a 2-0 whitewash, Jones was far from satisfied with the performance of his new-look team.

He added: “The biggest thing I have learnt on this tour is that to beat Argentina at the World Cup we are going to have to improve.

“To win at the World Cup, you need to be bullet-proof, and we’re not bullet-proof at the moment.

“In various games, they [Argentina] have edged us in certain departments. In the first half, they had a set-piece advantage.

“We can’t allow that to happen again. On Saturday, we got out of it and the first game we got out of jail a bit. We are too close to Argentina. At the World Cup, we need a gap.”
