Our list highlights who is on the hot seat as we enter the 2010 World Cup.
The pressure is on not because of South Africa's soccer prowess (they are ranked 83rd in the world), but because they are the sight for the first ever World Cup on the African continent.
The fans, security and environment must be top-notch to ensure a return visit.
On the field, South Africa must be ready to shine.
Since the 1986 games in Mexico, no host team has failed to reach the knock-out stage of the tournament.
Days removed from an embarrassing loss to China, and the controversial hand ball against Ireland, France's behind is firmly on the hot seat.
Coach Raymond Domenech has been under pressure since his country's weak World Cup qualifying campaign.
No Zidane and an aging Henry put pressure on those like Ribery and Anelka to step up to the challenge.
"Don't tread on me."
Well then you need to win.
The popular phrase has revolutionary roots, but is more commonly know as the slogan of the USA National Team.
In order to make sure no one indeed treads on them, they need to live up to their potential.
Landon Donovan, once seen as the savior of US soccer, needs to be just that. The US' fantastic run in 2002 was followed by an underwhelming performance in Germany in the 2006 games.
With a healthy Oguchi Onyewu, the United States looks capable of advancing to the knock-out stages but from there they must prove themselves.
Not since their win in 1966 has England held the World Cup.
Their best finish since was in 1990 when they placed fourth.
The core of England's squad (Lampard, Terry, Cole and Gerrard) are all at their peak and they are complimented by young stars like Wayne Rooney.
The loss of Rio Ferdinand is a problem but they are still favored to place first in Group C and anything but the trophy will be seen as a disappointment.
One of the most talked about people in this year's World Cup is not a player—not anymore.
Argentina's Head Coach Diego Maradona has been the center of intense speculation since he became the leader of the club.
Many have Argentina winning the tournament behind the skill of Lionel Messi, but some see Maradon's coaching style as a potential problem.
If Argentina loses early in the tournament, Maradona will have a lot to explain.
I had as many goals during World Cup Qualifying as Ronaldo did—a big old goose egg.
Arguably the best player in the world, Cristiano Ronaldo is at his peak physically (25-years-old) and coming off an impressive league campaign, but he must step up his international play if Portugal is to win.
The loss of Nani and being placed in the group of death with Brazil and Ivory Coast only increases the pressure.
An unsuccessful tournament could put Ronaldo's legacy into question.
Getting the monkey off their back with their win in Euro 2008 does not mean Spain is off the hook.
Arguably one the deepest and most talented teams in the tournament, Spain is the favorite to win it all.
A mediocre group and a powerful offense are all things that make the road to the cup easier, but don't count them in just yet, because Spain has an uncanny ability to under perform.
The team's best finish was in 1950 when they placed forth.
Since 1950 they have failed to qualify for four World Cups and their best finish was in 2002 when they reached the quarterfinals.
Spain has the star-power, but they must show up.
