Saturday's U20 World Championship Final was "Test level" according to England U20 head coach Jon Callard.
Callard's side fell short in their bid for three straight U20 titles, losing 21-16 to New Zealand.
The England U20 boss now expects to see many of the side, captained by Bath's Charlie Ewels, to feature in World Cups to come in the future.
”It was a Test level match, both sides were great with the passion and emotion they put on the field," Callard told World Rugby.
"It could have gone either way, the first 20 minutes by us were sensational, but we struggled in keeping the possession in the second half.
"I can’t ask more to my side, I’m sure that we will see many of them playing at World Cup in 2019 and 2023."
Ewels, a winner last year with England, said the whole experience had been "awesome" and would benefit the players in the future.
"To beat the best best sides in the world you have got to be on your game from minute one to 80 and I don't think we were today," said Ewels.
"It's an awesome group of lads, it's been an awesome experience and we will learn lessons from tonight and hopefully come back stronger."
