England boss Gareth Southgate revealed he had told the players after the game that he must be the "party-pooper" as they now prepare for the trip to Rome for a Euro 2020 quarter-final tie.
Goals from Raheem Sterling and Harry Kane in the final 15 minutes helped the Three Lions secure a 2-0 victory against Germany at Wembley and their place in the last eight of the tournament.
"It's a brilliant afternoon," Southgate told BBC Sport. "We talked about bringing enjoyment to the nation really and afternoons like this are what that's about.
"The players were absolutely immense, right the way through the team and the fans were as well. Only 40,000, but it's as good an atmosphere as I can remember at Wembley.
"We played extremely well. I think we deserved the win, but I've had to say to them (the players) straight away, look, 'I'm the party-pooper because if we don't capitalise on that on Saturday now, then it doesn't count for anything'."
Southgate was full of praise for both his goalscorers Sterling and Kane.
"Raheem, well they both have to constantly, has to prove people wrong all the time and Raheem has been immense for us over three, four years," Southgate said told the BBC.
"He knows we've got faith in him, we've got that trust in him and his performances have been electric, right from the start.
"For Harry it was a really important moment I think. When you're a centre-forward it doesn't matter what else you're doing in the game, you need those goals and I was pleased to see the second one go in I have to say."
Southgate was asked if his side's win helped ease the memory of his penalty shoot-out miss in the semi-finals of Euro 1996 against Germany.
The former England defender said: "I'm just so pleased. I was looking at the big screen and I saw David Seaman up there, the team-mates that played with me, I can't change that, so that's always going to hurt.
"But what's lovely is we've given people another day to remember and now we've got to go and do it in Rome."
Jack Grealish felt he was paying back the England fans for chanting his name as he came off the bench in the 2-0 win.
"I love it, it's part of the game and if you're getting talked about you're obviously doing something well aren't you," he told BBC Sport.
"I just take it in my stride and it was an unbelievable feeling to come here today and have the fans singing my name.
"It's weird because I usually have these fans booing me but when they are cheering my name like this and singing my song there's nothing more I want to do that pay them back with goals and assist so hopefully my goal will come soon.
"It's always nice knowing the fans are calling your name but it's not about me it's about the team and I just come on and try to create and I come on and played a part in the first goal and got the assist for the second."
Grealish also praised Kane, who had not scored in the previous three games at Euro 2020, for breaking his duck.
"This Euros has been different I think to many before, I think there's so much tactical stuff going on its hard for H (Kane) because he's probably our most talked about, probably our best player," he added.
"It's difficult because teams are going to try and double up on him and try and get him out of the game so I don't think it's anyone's fault in particular.
"But when the game opened up at the end as soon as Luke gave me the ball I was going to shoot, bring it onto my left foot and shoot but I saw H in the box so I crossed it for him."
