The 2015 Rugby World Cup will kick-start in another three day's time and the teams are sweating it out on the field.

The Pool A of the 2015 Rugby World Cup is being termed as the toughest group in the World Cup history by Rugby critics. Four of the top 10 teams in the world will battle it out in this pool to qualify for the knock-out stage and further.

England, Australia and Fiji will be taking a shy at the top two positions in the group. While Wales will be fancying their chances to cause a number of upsets during the group stage. Uruguay, who's ranked 19th in the world will face the toughest opponents.

England:

England, being the host team, have immense pressure on them. The last and only time they had won the World Cup was back in 2003. They are the only European nation to win the World Cup once in the 28 years.

Coach Stuart Lancaster would want his best players to step up to the occasion and win the World Cup in front of the home crowd. Sam Burgess, George Ford, Jonathan Joseph and Anthony Watson are the crucial players in the England lineup. They will be playing the opening match of the 2015 Rugby World Cup against the potential threat Fiji at the Twickenham Stadium on 18 September. It will be hard for Fiji to beat the host nation in front of a capacity crowd, which will be right behind their team.

Australia:

The Wallabies (as they are popularly known as) are one of the contenders of the World Cup. They are coming into this World Championship in England after winning the southern hemisphere's Rugby Championship. They have recently defeated the defending champions of the World Cup, New Zealand (All Blacks) and South Africa as well. The last time Australia had won the Rugby World Cup was back in 2003.

Drew Mitchell and Matt Giteau will be adding a lot of experience to their backline in the forthcoming World Cup.

Wales:

Wales had reached the semifinals of the 2011 Rugby World Cup and this time they are looking to make it big. They will face Uruguay in their opening fixture in which they will be looking forward to score as many points as they can. But they will be wary of their other opponents - England, Australia and Fiji. They are coming into the World Championship after a victory over Ireland in Dublin in a warm-up game and they would like to carry on with their winning momentum.

Fiji:

England will be their first opponent in the 2015 Rugby World Cup. They would want to be the reason for a number of upsets in this pool A. Having made it to the last eight twice before this, they will have to overcome the powers of England, Australia and Wales in order to proceed further in the tournament.

Uruguay:

Los Teros, as they are popularly known as, are making their third appearance in the World Cup in 28 years. They are the minnows in Pool A and they have a mountainous task ahead of them. It is highly unlikely that they will make it to the quarter-finals but they will try and give their best against the World powers of Rugby.
