Gareth Southgate wants to make the "impossible seem possible" by encouraging England to dream and embrace the challenge that lies ahead at the World Cup.
England's young squad head to Russia led by striker Harry Kane, who expressed his belief that England can win the World Cup just hours after being announced as captain for the summer.
Southgate is trying to bring such confidence out of his players. "Why would I limit what they feel is possible?" the England manager asked.
"My job is to allow people to dream. What's the saying? 'Make the impossible seem possible.'
"They are at an age and a hunger, and have an enthusiasm and no little quality, so that they can certainly keep improving.
"But we have got to improve to reach the latter stages of a tournament and that is going to take a lot of work over the next few weeks and a huge commitment, but I am seeing evidence that they're embracing that challenge."
England have shown quality and kinship during preparations, with Southgate pleased by the way his players are buying into the way he wants to work.
"I think that's allowing us to create an environment where they're actually having a go at things we're asking them to do, when sometimes I think, 'They're never going to go for this'," the Three Lions boss said.
"They're at times painstakingly putting up with some of the things I throw their way, so that I think would be more difficult with older players, I have to say.
"They'd possibly be a little less malleable and a little less open to new suggestions, but they really are having a go at everything and I think they are keen to show people how much it means to them to play for England.
"I think you're starting to hear some of their own stories and background, which I think is really important. And we're all England fans. You've seen pictures of them and I am the same.
"I've got a picture of myself in the shirt from 82 at home. I am lucky that there's some of me in a shirt playing and now I am proud to lead the team, so it goes right through the group and we're really looking forward to going.
"I've said to them, we're going to attack the tournament."
