Germany can ill afford another slip-up when they take on Sweden at the World Cup on Saturday, as the defending champions attempt to follow Brazil's lead by belatedly springing into life.
Joachim Low's side slumped to a 1-0 defeat against Mexico in their opening Group F match, paying the price for a calamitous first half in a performance that drew stinging, widespread criticism.
Lothar Matthaeus, the 1990 World Cup-winning captain, said he hadn't seen a Germany team "so weak at a big tournament for a long time" following the loss in Moscow.
The holders will likely be without defensive pillar Mats Hummels due to a neck injury, while Marco Reus could be handed a start after a bright 30-minute cameo off the bench against Mexico.
More from 2018 World Cup
"Everyone is ready to fight for their lives," said striker Timo Werner, who is again set to lead the Germany attack.
With 10 World Cup goals to his name, Germany will also expect more from Thomas Muller at his third finals appearance.
"The pressure is terrifically high, but we won't win both games if we beat ourselves up internally and look for the mistakes in each other," said Muller, with Germany to meet South Korea in their final match.
Sweden beat the Koreans 1-0 to join Mexico at the top of the section, but a stomach bug has prevented three players - Pontus Jansson, Filip Helander and Marcus Rohden - from travelling to Sochi.
They could yet make the trip separately, with Sweden also hoping Victor Lindelof can return after sitting out the opener due to an illness of his own.
"This is really what you spend your whole career and life working towards. It is an extraordinary opportunity to be involved in a World Cup match like this," said Sweden manager Janne Andersson.
"Whether we knock out Germany is one thing, but we have a chance to qualify and that is extraordinary."
Belgium return to action
Belgium can effectively lock up a last 16 berth with victory over Tunisia in Moscow in Group G, ahead of a blockbuster clash with England next week.
Romelu Lukaku scored twice in a 3-0 win over debutants Panama, and manager Roberto Martinez is trying to finally squeeze the best out of a squad brimming with talent.
"The World Cup does not respect generations, the World Cup doesn't respect individual names, it only respects winning teams," Martinez said.
Mexico look to build on Germany win
Mexico head into their showdown with South Korea after a "milestone" win over Germany, but a misstep in Rostov-on-Don would undo all that good work.
The Taegeuk Warriors are drawing inspiration from Asian rivals Japan and Iran as they bid to avoid a premature end to their Russian adventure.
"I had a suspicion the Asian teams in this World Cup would do well and I had the idea that we would do well as an Asian team too," midfielder Jung Woo-young said.
"It has caused a lot of excitement for us and we are even stronger in our belief that we can do it."
