We now know who the Rugby World Cup quarter-finalists are.

With the pool stages done and dusted, we have out lineup for the knockout stages.

Ireland face New Zealand and hosts Japan take on South Africa on the one side of the draw.

On the other, England will meet Australia while France stand between Wales and a second semi-final under Warren Gatland.

Most of them have played four times. England, France and the All Blacks just thrice.

But who has hit top gear and who still has more to offer? We've rated the eight teams left with the chance of glory in Japan.

ENGLAND: Smooth sailing without ever being tested

The first of the quarter-finals sees Eddie Jones' England face Australia. In terms of match-ups, England will favour this to Wales.

The Wallabies have struggled against England in recent times and current form shows no sign of that abating soon.

England have cruised through the group stages, seeing off Tonga, USA and a 14-man Argentina. It's been something of a cakewalk - with Jones' men not being tested.

Their final match against France was called off and while Jones may tell the media he's happy for the rest, he probably isn't thrilled behind closed doors.

England needed to step up the intensity and to carry on building minutes and momentum on the park. The break could hurt them if they start slowly against some actual decent opposition in Australia after a long lay-off.

AUSTRALIA: Perennial slow-starters can still be dangerous

Four matches. Three slow starts.

Even when they started on top against Georgia, they didn't turn their dominance into points - with blunt one-up rugby doing little to break down the Georgian defence.

Everything is a little slapdash in the Wallabies camp at the minute, whether that's Michael Cheika's approach to analysis, team selection or the laws of the game.

Yet, with Australia, you never really know. And they've proven more than capable of solving problems on the fly during matches.

NEW ZEALAND: Same old, same old from the All Blacks

It could only be through a technicality that New Zealand would finish a pool stage without winning all four matches and that's exactly what happened this time around.

Typhoon Hagibis saw their last match with Italy called off which saw them lose their 100 per cent record, but it won't matter much to Steve Hansen.

The big test was South Africa first up and they came through it well.

Make no mistake, they are still the best team in Test rugby.

The odd question remains, like where to play Beauden Barrett - full-back or fly-half? But otherwise, things are looking tentatively healthy for a three-peat.

IRELAND: Blunt attack threatens to ruin another World Cup

If New Zealand are to World Cups what Jim Carrey are to comedy, then Ireland have been to World Cups what Mariah Carey is to comedy.

But this should have been different.

Under Joe Schmidt, Ireland have built themselves up as contenders - yet once in Japan, it's threatened to go off the rails a bit.

They started emphatically with a blowout against Scotland, but defeat to Japan revealed a bluntness in their power game that could be exploited by the best teams.

That lack of cutting edge was apparent against Russia, although they did look a little better against Samoa.

The All Blacks now await. They've beaten them twice in the past few years - but they'll be kicking themselves for not topping the group.

WALES: Delivered when it's mattered

Four wins from four and a first topping of the pool since 1999.

On top of that, a first win over one of the southern hemisphere's big three at a World Cup since 1987. It seemingly couldn't get much better for Warren Gatland's men.

But, of course, it could.

 

Not just in the context that, as he said, they are 240 minutes away from changing their lives. But because there is still room for improvement.

The scrum is still a work-on, while Australia and Fiji did a good job of turning a usually resolute and solitary red wall into 15 individual and vulnerable individuals in defence.

But the attack - and squad - hasn't been hit as hard by the departure of Rob Howley as some might have expected and Wales will consider themselves favourites for the quarter-final against France.

FRANCE:  That old cliche about France isn't ringing true at the minute

You know what they say about France. If you don't, ask someone if they know. If the response is one of frustration, they know.

It's a worn-out cliche but it's not really rang true in this tournament.

We've largely known what team will turn up - a relatively poor one. They may have three wins from three, but none has looked convincing.

In particular, performances against Tonga and the USA were dreadful in patches. But a French team at a World Cup is a dangerous proposition - especially one that is winning.

JAPAN: Sparkling hosts should fear no one

It's not a hard and fast rule that the hosts have to perform well in a World Cup for it to be a success.

2015 was an entertaining tournament despite England crashing out at the pool stages.

But having Japan win four from four and top their pool is a big plus for the tournament - not least for the rugby they are playing.

It's quick, precise and astute. Their ball presentation and short passing is conducive to fast, running rugby.

But as they showed against Ireland, they have the heart and physicality in defence to stop bigger forces too.

South Africa will rightly be favourites, but the Miracle of Brighton won't be such a miracle if it happens in Tokyo next weekend.

SOUTH AFRICA: Boks starting to find ruthless streak

Many people's tip to win the Webb Ellis Cup, the Springboks are working their way back from an opening match defeat as they bid for a third World Cup crown.

Granted that defeat was against New Zealand, but they weren't ruthless enough against the All Blacks.

That killer edge has been there for easy victories against Namibia, Italy and Canada.

The draw looks good for them and they'll be keen to put the ghosts of 2015 to bed next week.
