Beside from the huge clash between the Springboks and the All Blacks, we have another exciting match to look forward to on Saturday when Argentina and France meet in the crucial Pool C match.
Argentina is a dark horse in the Pool that also have England in it and a win against France will help them getting into the playoffs.
France had a good preparation before the World Cup and except in 2015 they have always performed well in World Cups.
This with the All Blacks v Springboks match later on Saturday are the two games most are looking forward to in the first weekend of matches.
Head coach Mario Ledesma has named his strongest possible side to face the French in Tokyo and although they did not had a good Rugby Championship, this Argentina side is a very good side.
Agustin Creevy, Juan Figallo and Nicolas Sanchez will all appear in their third World Cup after being named in the run-on side, but there is no place in the matchday squad for veteran back-row Juan Manuel Leguizamon, who has already represented his country in three World Cups.
Guido Petti will get his 50th test cap on Saturday packing next to Lavanini.
Veteran duo Guilhem Guirado and Louis Picamoles are both set to appear in a third World Cup.
Guirado will lead the team from the front row and are the only team that loss in the 2015 quarter final against the All Blacks.
Medard will play in his second World Cup
France have a good balance between a strong enough pack to compete with the best and a backline that have enough speed to score tries.
Argentina scrums have been a worry and the French will surely try and put pressure on the Pumas in that area.
Set pieces are going to be important but the worry for both teams will be their defence as they have been letting tries through way too easily.
This is definitely one not to miss.
