Germany-USA Clash: What You Need To Know
As Germany and the USA meet in the battle to qualify for the World Cup knockout stage, Sky News looks at the key talking points.
Germany are top of Group G with four points going into the 5pm kick off, ahead of the USA but only on goal difference. Portugal and Ghana each have one point.
The game will be played in tough conditions as torrential rain hit the Brazilian beach town of Recife just hours before kickoff.
If the US win, they are through and win the group.
A draw puts both Germany and US through, with the Americans advancing as runner up to Germany, no matter what happens in the other game.
This has raised fears the teams might collude on a draw, although both sides insist that will not happen.
If the US lose, things get complicated. To name a few scenarios:
If Portugal and Ghana draw, the US advance.
The Americans face elimination if they lose by one goal to Germany and Ghana beat Portugal by two goals or more.
If Portugal beat Ghana 5-0, the Americans are knocked out.
US coach Jurgen Klinsmann faces the nation he helped win the 1990 World Cup title and coached to the 2006 semi-finals.
When the US and Germany met for the first time in the group stage of the 1998 Cup, Klinsmann scored the second goal in a 2-0 win.
The teams played in 2002 in the quarter-finals, when Michael Ballack's 39th-minute goal gave the Germans a 1-0 victory.
The Americans still complain Scottish referee Hugh Dallas declined to award a penalty when Gregg Berhalter's 49th-minute shot hit the left arm of defender Torsten Frings at the goal line.
:: From Friend To Foe
Klinsmann and Germany coach Joachim Loew are old friends but their friendship is on hold.
Klinsmann was Germany's manager with Loew his assistant when they reached the World Cup semi-finals on home soil in 2006.
"We are very close friends," Klinsmann said. "We think alike and come from the same region and we have always been in contact.
"But coming into this World Cup, everyone is doing the best he can do, so we leave the phone calls and text messages for a few days to get the job done."
:: 'Biggest Game Our Of Lives'
The US team is confident going into the clash, backed by record TV viewership and growing interest at home.
"The country is in a soccer fever and they're glued to the TVs when we play," midfielder Kyle Beckerman said.
"It's the biggest game of all of our lives," he added. "Any fatigue in our legs will be erased. We've got to give it everything we've got and more."
Sunil Gulati, the president of the United States Soccer Federation, said: "I think for the first time in our history - recent history, I'm not going to talk about 1950 or before - our players believe they're capable of beating anyone."
:: Watching From Space?
Will US astronauts Reid Wiseman and Steve Swanson and German astronaut Alexander Gerst be watching from the International Space Station?
In a couple of videos from space, they have kicked a ball in zero gravity, sent a good luck message to all teams, and practised goal celebrations.
Will they be cheering at the final whistle?
