Gloucester star Ben Morgan says England's tour of Argentina will have a considerable impact on the national side this season.
Stuart Lancaster's men claimed their first series victory over the Pumas in 32 years this summer and in the absence of England's Lions contingent, a host of young stars made the most of their chance to shine.
Marland Yarde, Christian Wade, Kyle Eastmond, Matt Kvesic and Billy Vunipola all impressed and were rewarded with a place in Lancaster's elite player squad earlier this month.
"That sort of tour is just a great opportunity for new people to come in and prove what they can offer," Morgan said.
"And I think everyone did that. You could see it in the way we played. Everyone stepped up and really impressed, and that reward has been achieved by being named in the elite squad.
"I don't think the tour exceeded expectations, we were just very pleased with how well we executed our plays. We've got the ability to be able to play like that, but it doesn't always come off through inaccuracies and discipline and that sort of thing.
"But the way we managed to deliver how we wanted to play was exactly what we were looking to do.
"And by having players coming through and taking their opportunities it means the competition in the squad across the board is at a different level.
"By having such competition it really drives the best from players and makes it a better team.
"If you are slack at any point, there are about three or four people ready to take your spot. It really is a case of being at your best for every performance because there are so many people itching to be in that shirt.
"Just by being in this England environment, where you've got such attention to detail in your forward play, your back play, your defence, it really does develop you as a player. You are always hungry to be around the environment.
"What I have experienced with England has been fantastic. Stuart has brought belief into our squad and made it a culture we want to be in and around.
"We are looking for lots of small details that we can develop. The whole England set-up back to the clubs is a really healthy relationship where everyone is on the same page and trying to achieve the same things.
"There is no separation, because when you go back to your club you are still trying to work to the same thing, and that makes a really big difference to how you can approach international rugby."
