Boks in final, don't know how? An idiot's guide to the Rugby World Cup

Here is a dummy’s guide to the Rugby World Cup:

What is the Rugby World Cup?

The Rugby World Cup is a 20-team rugby union tournament that takes place every four years on an odd year.

The first edition was a 16-team one that took place in New Zealand. The number of teams in the amateur-era World Cups (1987, 1991 and 1995) remained at 16 and in the professional era (1999 onwards) they increased to 20. That hasn’t changed.

How many teams have won the Rugby World Cup?

Only four countries - New Zealand (1987, 2011 and 2015), Australia (1991 and 1999), SA (1995 and 2007) and England (2003) - have won the tournament. No Northern Hemisphere team won in the amateur era. England remain the only Northern Hemisphere team to have won the tournament.

How did England and SA reach the final?

England topped Pool C ahead of France, Argentina, Tonga and the US, from where they defeated Australia (40-16) and New Zealand (19-7) in the respective quarterfinals and semifinals. This is their first final appearance since losing the 2007 final to SA, 15-6.

SA finished second in Pool A behind New Zealand, but proceeded to beat Japan (28-3) and Wales (19-16) in the quarter and semifinals to reach the showpiece game.

Where will the final be played?

The ninth Rugby World Cup final will be played at the International Stadium Yokohama, with the ground becoming only the second to host a Soccer World Cup and a Rugby World Cup final.

The Yokohama ground, where SA began their World Cup campaign with a pool stage loss to the All Blacks, hosted the 2002 Fifa World Cup final between Brazil and Germany. The first ground to host the two finals was Paris’s Stade de France in St Denis, with the arena hosting the 1998 Fifa World Cup and the 2007 Rugby World Cup finals.

Who are the captains?

Siyamthanda Kolisi will be captaining SA from the loose-forward position while Owen Farrell will be leading England wearing the No 12 jersey. Kolisi will be taking part in his 50th Test while Saturday’s final will be Farrell’s 83rd appearance for England.

Who will be the referee?

Frenchman Jérôme Garcès will be officiating the final. The 46-year-old has never been a popular appointment with South Africans, as the Springboks haven’t always done well with him in charge. They’ve won only five of their 15 Tests with Garces officiating, but crucially, the last one was the semifinal win against Wales.
