England can book their ticket for the second round of the World Cup by defeating Trinidad and Tobago on Thursday, while Germans partied all night after a last-gasp victory over Poland put the host nation on the cusp of reaching the last 16.
Oliver Neuville came off the substitutes' bench to score the winning goal in stoppage time of the 1-0 victory in Dortmund, sparking celebrations across the country.
But police detained more than 300 people in the city before the match after German hooligans sparked clashes, ending five days of calm at the tournament.
Germany now top Group A after two victories from two matches, and coach Jurgen Klinsmann said the team was being carried along on a tide of home support.
"We have got the support of the fans behind us and the atmosphere in the country is fantastic," Klinsmann said.
"They want to make things happen and the team will give their all for them. It is a big party."
Klinsmann said a victory in the final Group A game against Ecuador in Berlin on June 20 was essential to ensure Germany win the group and, in theory, give them a kinder draw in the knockout phase.
"We will enjoy this win and focus on Ecuador," Klinsmann said.
"We want to finish top of this group and play in stadiums we have got used to."
The defeat means Poland are all but out of the tournament despite a battling display.
After an unconvincing performance in their opening win over Paraguay, England want to re-establish their claim to be a serious contender for the title when they take on the Caribbean minnows in Nuremberg.
Coach Sven-Goran Eriksson could risk his most influential player, Wayne Rooney, in the clash against Trinidad and Tobago, who held Sweden to a shock draw in their first ever World Cup match.
Rooney, who has made a rapid recovery from a broken bone in his foot, could make an appearance as a substitute.
Police were out in force in Nuremberg, which is closely associated with Germany's Nazi past.
England were kicking off at 1600 GMT after Ecuador, who are also targeting one of the two qualification spots from Germany's group, take on Costa Rica in Hamburg at 1300 GMT.
The Ecuadoreans turned in a strong performance to beat Poland 2-0 in their opening game, while Costa Rica slumped 4-2 to Germany.
Sweden hope to get their Group B challenge back on track when they meet Paraguay in Berlin's Olympic Stadium at 1900 GMT.
Meanwhile, there was a health scare for Brazil's star striker Ronaldo, who was taken to hospital in Frankfurt after feeling unwell but was later allowed to rejoin the squad after tests showed nothing out of the ordinary.
The Brazil Football Confederation (CBF) said on its website that the 29-year-old Real Madrid player started feeling unwell on Wednesday evening after the Brazilians had returned to their training base following the 1-0 win over Croatia in Berlin.
Ronaldo appeared overweight and out of form in the match.
Coach Carlos Alberto Parreira, however, has said he intended to play him in the Brazilians' next game against Australia on Sunday.
