Henderson hopes his players will “walk away with memories they will never forget” in the semi-final, but the main aim is to see them break into the senior team in the future.
The final England Under-17 team to play matches in the World Cup final included Lionesses Niamh Charles, Alessia Russo, Georgia Stanway, Ella Toone and Lotte Wubben-Moy.
“We believe these tournaments and experiences are crucial to their development,” Henderson said.
“We want to be in more big tournaments like this and expose players to what it’s like to participate in them from a pressure perspective and also culturally.
“The two video games [against Mexico and Japan] They have almost certainly been the two craziest football video games that have excited us.
“They showed the true character of this team, who we are as a team and how much we believe in each other.”
Spain are heavy favorites having easily beaten England at the last Euro, but Henderson says his team wants to “show off on the big stage”.
“A lot of work was done in preparing for the tournament. We have talked about being united, together, present and enjoying the moments together,” he added.
“We also want to be relentless in the way we play football and shine on the big stage. These are the values we have in this team.
“In fact, we believe that we will have the ability and we have loved handling the combined demanding situations. I know the mentality of the players and they are still not happy.
“We want to go as far as we can. As long as every staff member and player can say they did the best they could, that’s what we want.”
