With Japan's convincing victory over Scotland, the World Cup quarterfinal table has officially been set, and with it come four mouth-watering fixtures. 

In three weeks, we'll have a 2019 Rugby World Cup champion. Will we see a new name etched onto the Webb Ellis Cup? Or will we see one of the usual suspects lift the trophy again? 

Whoever it is, they'll have to first get through a stacked quarterfinal round. Here's the rundown:

England vs Australia

The battle on the field figures to be epic.

Two of the world's most exciting teams meet in a clash of different styles. England are a well-organized, skilled, and powerful team that sets good platforms with strong forward play. This frees up their wealth of riches in the backline. Look for Billy Vunipola, Kyle Sinckler, and Maro Itoje to lead from the front with their carries. 

Australia have a bit more dynamism and enterprise in their attack, boasting a number of different athletic ball-carrying options. They also have playmaking distributors all across the field, particularly when they play Matt To'omua, James O'Connor, and Kurtley Beale at the same time. 

Key Matchup

Manu Tuilagi vs Samu Kerevi

The big matchup in this contest will be the colossal showdown in the midfield between England's Manu Tuilagi and Australia's Samu Kerevi. The two big centers have been on fire this World Cup, both offensively and defensively.

Both will get their meters and both will make their big hits, but you can count on one of the two to make a game-changing type of play that could just prove the difference between winning and losing.

New Zealand vs Ireland

Ten months ago, many pegged this as the probable World Cup final, after Ireland recorded their second defeat in three occasions over the All Blacks. 

Oh how times have changed.

Ireland now meet New Zealand in the quarterfinals, after their surprise loss in the pool stage to Japan. The Irish haven't had the best 2019, twice losing big in the Six Nations (to England and Wales), and then shipping a record 57 points to the English in the summer.

The All Blacks are looking like the usual buzzsaw that they are, and it would be nigh impossible to say they aren't favored in this one. But Ireland somehow seem to have the All Blacks' number lately and if the Irish front up like they can it could certainly go their way. 

Key Matchup

Johnny Sexton vs Richie Mo'unga

It's one of the game's best veterans against one of it's best rising stars, as flyhalves Johnny Sexton and Richie Mo'unga steer the ships for their teams this weekend. 

It's no secret that Ireland go the way that Sexton goes. If there's anyone out there more important to their team in this World Cup, he's probably a unicorn. Sexton is more than just the driver of the bus. He is the engine, the oil, and the gas that make the bus go. If he can come through the game healthy, his team has a decent shot. 

Richie Mo'unga on the other hand is the man of the moment in New Zealand. 

Having taken the reins over at first-receiver from two-time world player of the year Beauden Barrett, heaps of pressure were mounted on his shoulders.

However, Mo'unga has one of the coolest heads in rugby and seems to thrive under the pressure. This will be the biggest game of his young career to date, but you can bet that will only bring out his best. 

South Africa vs Japan

You can already taste the excitement for this one in Japan. 

Following Japan's historic pool play performance, the Brave Blossoms are in their first ever quarterfinal, and they've got the support of an entire nation behind them. 

They etched their name into rugby folklore at the 2015 World Cup by beating the mighty Springboks. Now they get a chance to beat them in a knockout fixture and prove Japan is genuinely one of the world's best teams. 

The Boks will no doubt have revenge firmly on their minds, but they know full-well that it won't come easy.

South Africa have looked one of the stronger, and certainly one of the deeper teams thus far through pool play. They were able to rest some of their key starters in pool play against Canada and Namibia, meaning they should be fresh when they take on Japan.

Key Matchup

Kotaro Matsushima vs Cheslin Kolbe

This has to be the most electric matchup we've seen so far in the competition. 

Matsushima is tied for the lead with five tries this World Cup, while Kolbe is sure to be on the shortlist for world player of the year at the end of this season. 

Both wingers have the rare ability to make their man miss, even with less than a yard of space to work with. They have pace, balance, and strength that belies their slight statures. It's going to be shocking if one or both of them don't get their finger prints all over this game.

Wales vs France

The last time these two teams met in the World Cup, France advanced to the World Cup final after holding off a gutsy 14-man Wales team, 9-8, following Sam Warburton's first half red card. 

This time around, coach Warren Gatland and his Welsh side are determined to avenge that crushing loss. Players like Alun-Wyn Jones, Jonathan Davies, George North, and Leigh Halfpenny are still around from that game and want to take Wales to heights never-before reached. 

On the other end, France will be seeking revenge for their loss to Wales in this year's Six Nations, when the French blew a 16-0 halftime lead at home to ignite Wales' Grand Slam campaign. 

Wales are loaded with experience and reliability, whereas France bring with them youth and much unpredictability. Young halfbacks Antoine Dupont and Romain Ntamack will be huge factors in deciding how the French go. 

Key Matchup

Welsh Back-Row vs French Back-Row

In a game that is going to be tight, it's the battle between the loose-forwards that will go a long way towards determining the winner. 

Both teams are very physical, and the point of contact is going to be a massive component to this match. Wales' back-row isn't the biggest by any means, but Justin Tipuric, Aaron Wainwright, and Josh Navidi are all three as good of tacklers as you can find on the planet. 

France's options in the loose are all powerful and athletic. Wenceslas Lauret, Charles Olivon, Gregory Aldritt, and Yacouba Camara are all deadly when they get forward momentum. With the abilities France have in the backline, the contest at the gainline is highly important in setting them free.
