There are 40 pool games at the World Cup but some are more important than others. Rugby writer Steve Hepburn looks at five key games which will decided the quarterfinalists.
England v Argentina
Dunedin, tomorrow
This game is all about statements. Is England on the right track and can Argentina repeat its heroics of four years ago? England must negate the power of the Argentinian front five.
The side that loses this game will have a tough road to get out of the pool and, if it does, it will then face a quarterfinal against the All Blacks or France.
France v New Zealand
Auckland, September 24
Motivation should not be lacking on either side. The All Blacks should go into this game confident but the French can never be taken lightly. If the All Blacks lose at fortress Eden Park, then start sharpening the pencils for coach Graham Henry's obituary.
Argentina v Scotland
Wellington, September 25
Scotland has made the quarterfinals of every World Cup but could be ripe for the picking this time. Games between these teams usually end in favour of the home side, although Scotland did win twice in South America last year.
Who wins in Wellington may depend greatly on who can master the stadium's tricky wind.
Fiji v Samoa
Auckland, September 25
There will no quarter asked and none given in this battle between Pacific Island nations. Samoa looks the better side on paper but Fiji tends to rise to the occasion in World Cups.
The key man may be referee Bryce Lawrence, as the side the can keep its discipline will come out on top.
Ireland v Italy
Dunedin, October 2
The last match of pool play and one with plenty riding on it. The Italians have never made it to the quarterfinals at a World Cup and, with coach Nick Mallett signing off after the tournament, the Italians will be hoping he has can extend his tenure by another week.
The Irish have plenty of talent although many of their players could be past their peak.
