Portugal have had a tough time in their World Cup qualification matches and they just sneaked past Sweden by a point to qualify.
They face Korea DPR, five-time champions Brazil, and Ivory Coast in Group G which has been touted as the "Group of Death."
Portugal are favorites to qualify from the group alongside Brazil but football is won on the field and not off it, so Portugal needs to prove themselves worthy of qualifying for the next rounds.
In this slideshow we will take a look into the five factors that Portugal need to qualify from their Group.
The Portuguese wonder boy has failed to hit top form after his record-breaking transfer from Manchester United last season. His season has been marred by injury and the Portuguese has moreover been overshadowed by performances of the slight Argentine wizard Messi.
This World Cup is Ronaldo's opportunity to achieve more glory. If he can hit top form during the World Cup, his country will have a chance to progress further in the World Cup tourney.
The whole nation will be looking forward to watching their gifted player and Portugal needs Ronaldo to be at the top of his game to ensure their passage into the next round.
Portugal's main weakness in this edition of the World Cup is their defense. The Portuguese defense is highly inexperienced. With the experienced Pepe just recently recuperating from injury, Portugal needs him to recover fast and find his mettle.
The 27-year-old defender is a key figure in the Portugal team. The team has been boosted by his return to first team action. The Real Madrid man needs to get back his form as he shall have to shoulder the responsibility of Portugal's defense.
If Portugal can overcome their defensive problems, they have a good chance to progress further in the finals. Pepe will be the man to take all of the responsibilities in the defense, so Portugal will be hoping that Pepe recovers fully and does what he does best.
Portugal has been seeded in Group G, the so-called "Group of Death", along with Brazil, Ivory Coast, and Korea DPR.
They are favorites to qualify from the group along with Brazil, but they need to register wins against the other two teams in the group.
Portugal are favorites to win against North Korea but they need to keep their guard. Their trickiest group game will be against Ivory Coast. The African nation will be looking to make an impression in their second appearance after a poor performance in the 2006 World Cup.
With their prolific goal-scoring striker Didier Drogba in top form, he is bound to give the weak Portuguese defense a tough time. Accompanying him will be his club mate Salomon Kalou who also had a great season with Chelsea.
They also have the "Toure brothers" in their squad, who have been top class for their respective clubs.
Portugal needs to win against the Ivorians if they want to ensure a smooth passage to the next round. A draw or loss can end Ronaldo's dream of glory prematurely.
So Portugal needs to win their matches against Ivory Coast and North Korea to ensure their qualification for the knock-out rounds.
Another drawback of the present squad is their lack of consistent performance. Portugal just scraped through the qualifiers to make it to the finals.
Their qualification was characterized by inconsistent performances. They played a good match and then lost the next one. They just sneaked through into the playoffs where they beat Bosnia and Herzegovina to qualify for the 2010 FIFA World Cup.
A single inconsistent performance and Portugal's dream of qualifying for knockout stages will be ended. The team needs to keep their focus in the group stages.
Brazil are the favorites to win the Group of Death and qualify to the next round. The five-time World Cup champions will be favorites to win against Portugal.
If Cristiano Ronaldo and Co. can repeat the feat predecessor Eusebio and his team achieved way back in 1966, it might help them top Group G and avoid facing Spain in the next round.
The Portuguese team should be charged up when they clash head-to-head with the Samba boys on June 25. If Brazil loses to Portugal it will be a feather in the cap for Carlos Queiroz's boys.
Their win might even see the World Cup favorites leave early which will be a real shocker. Portugal needs to repeat their 1966 World Cup feat to be assured of their place in the next rounds.
