England U21 boss Stuart Pearce is determined for their Euros victory over Spain not to go to the players' heads.
"It's a million miles from being a success at the moment," Pearce said.
"Firstly, England against Germany is a massive match and we are going to attempt to win. Every time those two countries play there is a lot on it.
"You get judged on whether you win, lose or draw when you wear your international jersey. I don't know if I will rest players.
"In these tournaments, if you take take your foot off the gas for one moment it's fatal. You never pick up the tempo again.
"I've seen it before and it won't happen here."
Pearce dropped Theo Walcott for the Spain game, bringing him on just before the goals started going in, with the Arsenal winger setting up the second.
"We've got pace on the counter-attack, and the modern game is about the counter-attack.
"We also have a strong mentality. We've got guts in abundance but have to pass the ball a bit better."
