England head coach Stuart Lancaster reckons his squad have made significant progress in the successful tour of South America.
Lancaster is already preparing England for the 2015 World Cup on home soil, and he believes the experienced gained on the current tour will prove invaluable.
As well as coming through the four games undefeated, England appeared to have some strength in depth with Matt Kvesic, Christian Wade, Marland Yarde and Kyle Eastmond all proving they are comfortable at international level.
Lancaster said: "It's a pleasing step forward. This tour was always going to be critical in our development towards 2015 because it gave the opportunity to bring other players through.
"It gives me confidence and also reassurance that the direction we are going in is the right one.
"I was always confident that we had quality players coming through the pipeline. They have played in big games in the Premiership and in Europe and now they are making the step from club to country.
"I want to create an England team where everyone feels comfortable in coming into and playing whether it is your first cap or your 31st cap.
"It was really pleasing to see people come into the team, slot in straight away and look like they had been part of the team for a long time."
