Roy Hodgson wants England to erase the memory of their painful and sobering defeat to Chile.
Exactly one month ago Hodgson was all smiles as he hosted a post World Cup qualification bash in a swanky hotel in London's West End.
The England manager had every reason to be happy. His team had just triumphed over Poland to secure a once-in-a-lifetime trip to Brazil for the World Cup.
He was in a bullish mood, too, decreeing that no nation would be shouting "whoopee" at the prospect of facing England.
Yet one month on, that is probably what the Germans are thinking right now ahead of Tuesday's visit to Wembley.
England were poor against Chile. There is no escaping that. The South American side were clinical in front of goal, they never seemed rushed on the ball and they cleverly stifled play in the second half to prevent England finding any rhythm at all.
Germany will be far more formidable opponents so although Hodgson stressed lessons must be learned from the defeat, he wants to move on quickly.
"The last two wins at Wembley were vitally important but against Chile we have seen the other side of football," the England manager said after the 2-0 loss.
"A month ago we were dancing around and congratulating ourselves and basking in the glory of having achieved our goal but we have to accept that we have left Wembley with a defeat.
"It doesn't happen very often, it's something none of us are happy to do, but that is what football is.
"It is sobering, all defeats are very sobering. We are going to be disappointed and angry that we couldn't provide the fans with a victory, but it would be foolish for us to take that disappointment in to the next game.
"They will have to make certain that they pick themselves up and go again."
Hodgson gave the players Saturday off to recharge their batteries ahead of Tuesday's game.
England are hopeful that Steven Gerrard, Daniel Sturridge, Kyle Walker and Rickie Lambert will all return, but Phil Jones' position is in doubt after he suffered a groin injury against Chile.
Joe Hart, Ashley Cole and Andros Townsend are expected to return to the starting XI.
Without Gerrard's presence in midfield, England lacked creativity on Friday, but a bigger concern for Hodgson was his team's profligacy in front of goal.
Phil Jones, Wayne Rooney and debutants Adam Lallana and Jay Rodriguez all spurned chances, and Hodgson knows his team cannot be as wasteful against Joachim Low's dangerous side.
"We know that we will have to be better at taking our chances," Hodgson said.
"There were quite a few occasions in the Chile game where the chances where there. We were behind them, but they were much more clinical in their finishing."
Hodgson's decision to hand Rickie Lambert his debut in August paid off handsomely when he scored the winning goal against Scotland with his first touch.
There was to be no fairytale bow for his two Southampton team-mates Lallana and Rodriguez, however.
Of the two, Lallana did the most to push his claim for a place in Hodgson's World Cup squad. The Southampton captain showed little sign of nerves, taking on his marker on several occasions, and there is a chance that he could occupy one of the flanks on Tuesday, with Townsend on the other.
Rodriguez failed to impress, appearing nervous throughout his hour on the pitch. Hodgson has told the midfielder he should not be disheartened, however.
"It was a very tough one for Jay, I thought," Hodgson said.
"Lallana actually played well and did some very good things. Jay was fine. He worked hard, did all the right things and he must not in any way be disappointed with his performance.
"He is a guy we will keep watching. It was a tough one for him to come in and play in, especially when we were 1-0 down early on and Chile had their tails up."
