Fullback - Ayumu Goromaru
Goromaru has been the figure head of the Japanese bid for glory at this World Cup. He has been a constant attacking threat, hitting the line with ferocity using his considerable bulk do make consistent gain-line successes. But it has been his kicking that has set him apart, out of hand it has been accurate and powerful putting Japan in the right areas of the pitch from which to act out their game plan, off the tee he has been nothing short of quality. It has always been a problem of smaller nations, lacking a quality goal-kicker who could keep the score board ticking over, not so for Japan this year with Goromaru kicking well into the 80%'s which is expected of Tier One goal kickers.
Honourable Mentions: Mike Brown, Joaquin Tuculet
Right Wing - Nehe Milner-Skudder
New Zealand have not looked anywhere near they're best at this tournament, making a lot of mistakes where normally there'd be none. Milner-Skudder has been a shining light amid a pretty poor showing, I picked him to be a star at this World Cup and he's come through on that promise. His jinking feet have wrong footed multiple defenders, allowing him - despite his small frame - to work his way over the gainline and offload the ball. He's also show an innate ability to finish tries squeezing a couple in at the corner with remarkable agility, but can also set them up for others around him with subtle hands and a knack for offloading.
Honourable Mentions: Anthony Watson, Santiago Cordero
Outside Centre - Damian De Allende
This is a tough one to do, because no outside centre has stood out enough so far, so instead I've moved De Allende from 12 to 13, it seems a reasonable enough move for him, with his strong running and surprising turn of pace. His most shocking trait is his ability to move his large powerful frame around defenders, he is surprisingly light on his feet. I was surprised to see him dropped in favour of De Villiers for the opening game, but an unfortunate injury to the national captain meant that he got his chance. He has really brought the South African attack to life at the end of the pool stages, and could be a crucial player for them in the quarter final against Wales.
Honourable Mentions: Mathieu Bastareaud, Scott Williams, Ciaran Hearn
Inside Centre - Matt Giteau
He has just oozed class in the Australian midfield, alongside Bernard Foley was responsible for the shredding of the England back-line. He offers a left footed option for clearances, and a creative brain with the skills to execute an attacking game plan both sides of the breakdown. It hasn't just been his skills, he has put his body on the line again and again for his home country, proving that the effort put into bringing the ex-pat's back into the fold has been worth it, willing to take the ball into contact hard and do what it takes to win the game. Not to mention a nicely finished try, showing he hasn't lost too much pace, against England.
Honourable Mentions: Sonny Bill Williams, Robbie Henshaw
Left Wing - DTH Van der Merwe
Another easy pick, in a Canada side that has played well in most of their games, and probably deserved more than four losses. DTH has been nothing short of world class, busting tackles, chasing down ever kick, scoring in every game, there is nothing more you want from your winger. He would walk into any other side at this World Cup, hopefully Canada can up their game and build a team around him four years down the line.
Honourable Mentions: Nemani Nandolo,
Fly Half - Daniel Biggar
Engineered a Wales win at Twickenham with a fearless display, imperious in the air, lethal from the tee, and a general on the field who makes the right decision at the right time. Almost designed a victory over the Wallabies with superb defence and aerial ability, but missed his first kick of the tournament that day too. While everyone else around him has been falling foul of injuries he has provided a steady rock from which Gatland has formed his back division. He made some decisions that potentially cost the game against Australia, but deserves his sport
Honourable Mentions: Bernard Foley, Nicholas Sanchez
Scrum Half - Fourie du Preez
Nothing has proven the veterans worth to the South African team than the fact he was missing against Japan when South Africa had no doubt their worst performance in a long time. du Preez provides a wealth of experience and precision that a youthful looking back-line has needed. He dictates how South Africa play, controlling the style and making sure they are the team dominating the territory and possession. He will never be a scrum half who can make the break or score many tries, but he controls the tempo and make's sure the exciting back-line functions as peak efficiency.
Loose-head Prop - Scott Sio
Who would have thought that an Australian prop would get on a World XV? But the Australian scrum has been nothing short of gigantic, I mean when a team scrummages England off the paddock - the Twickenham paddock at that - you know they are a force to be reckoned with. His force around the park is nothing to be sniffed at either, strong ball carrying with an distinct Australian passing ability. Utterly superb across every facet of the game that he is needed for, and a little more besides, and he's still a relative youngster, foundations for a dangerous Australia for years to come.
Honourable Mentions: Campese Ma'afu, Marco Ayerza
Hooker - Guilhem Guirado
A difficult choice, but eventually I had to go with the rampaging, free running Frenchman. On more than one occasion we have seen him on a bullocking run up field put through a hole by one of his compatriots. He has incredible speed for a hooker, something that is fast becoming a trait of international hookers across the world, he also executes the basic's extremely well with his work at the line out and the driving maul. Is an important player for France as they head into a quarter final battle royal against New Zealand.
Honourable Mentions: Dane Coles, Agustin Creevy
Tight-head Prop - Rabah Slimani
Another French front rower who has impressed in the loose at this World Cup, completing a delightful chip and chase by Freddie Michalack to score under the posts, he has also been one of France's chief ball carriers around the breakdown. However it's been at scrum time where he has been most impressive, ousting the set piece behemoth that is Nicolas Mas is no mean feat, and yet Slimani has done it with ease once again giving France a scrummaging platform from which to attack. Could be crucial against a sub-par New Zealand scrum.
Honourable Mentions: Sekope Kepu, WP Nel
Second Row - Iain Henderson & Leon Nakarawa
With Paul O'Connell's recent forced retirement, it is of great relief to the Irish fans that the Ulsterman Henderson has be putting in some of the performances of the tournament. He has been a force to be reckoned with in the contact area, stealing far too many meters than anyone should at international level, constantly pumping the legs into and through the collision dragging flailing defenders with him. Combine this with his ability to keep the ball free and look to deliver it out of the contact, and his strength in the line out and he has burst on to the scene at the right time for the Irish faithful and Joe Schmidt.
The Fijian Nakarawa has been nothing short of superb, strong into the contact, devilishly good at offloading, fierce in defence but perhaps most impressively is his ability to win turnovers. For such a tall man his ability to get into a ruck and win the ball is unparalleled, and it has been a source from which Fiji rattled all three of the Pool A giants are some stage. His confidence with ball in hand is up there with Sonny Bill Williams, and with his added height he is able to look for the pass over the top of reaching defenders. Nothing short of wonderful to watch and it's a shame he is leaving the tournament.
Honourable Mentions: Alun Wyn Jones, Lood de Jager, Joe Launchbury
Blindeside Flanker - Mamuka Gorgodze
Played pretty much everywhere across the backrow at some stage this tournament, and put in an incredible performance no matter what shirt he wore. His leadership qualities are second to none, dragging is team forward with grit, determination and aggressive willpower, and because of that Georgia secured automatic qualification for the tournament in 2019. He has a fantastic report with the referee's, is never shirking in his defensive duties, and scoring tries at the other end of the field too. Nothing short of fantastic, another who every team in the world would love to have him in their side.
Honourable Mentions: Francois Louw, Peter O'Mahony
Openside Flanker - David Pocock
While he has been playing at No. 8 all tournament, he is naturally and naturally an openside. There are not enough adjectives for how good he has been, especially after two years out of the game. He wins uncountable number of turnovers, and those times he doesn't he slow the ball so much the Australian defence has reformed and looks entirely solid. The entire world knows what he can do in defence, its with the ball in hand that he has upped his game. At the back of the driving mauls he has turned close range try scoring into an art form, and he has stepped up his ball carrying and taking it to the opposition. Getting away without a formal citing after a suspicious knee against Wales was crucial to Australia at this World Cup.
Honourable Mentions: Michael Hooper, Sam Warburton
Number 8 - Talupe Faletau
Wales' scrum has been shambolic, and despite this Wales have pulled off the impossible and qualified for the knock-out stages, that is in no small part down to Faletau. He has pulled off feats the defy belief at times, gathering the ball behind a retreating pack and still making considerable yardage while staying on his feet long enough for support to arrive and secure possession. His work in the loose has been superb as well, often appearing in the wider channels to eat up the distance in front of him, before showing a soft pair of hands to release the players around him. He is paramount to Wales' chances at this World Cup, and is fast becoming the best No. 8 in the world.
Honourable Mentions: Louis Picamoles, Amanaki Mafi
