Patrick McKendry
Wales' injury problems have to bite at some stage and they probably will here against a fairly limited Springbok team.
Wynne Gray
Have dealt with adversity all the way through, sawn off in the semis last time, Gatland and Warburton leadership.
Rugby World Cup 2015:
Why France will definitely beat the All Blacks
Joe Moody in squad to face France
Hansen - 'I understand why people at home are worried'
London Mayor Boris Johnson knocks over 10-year-old Japanese schoolboy
France recalls Parra, Bastareaud to bench
Dylan Cleaver
Wales too beaten up in the backs and they won't outmuscle the Boks.
Nigel Yalden
Wales will fight to the end but that big Bok pack is going to lay the platform for du Preez and Pollard to dictate terms
Elliott Smith
Ten days rest for the Boks for a team that has shown signs it could be finding its mojo will be too much for Wales.
NEW ZEALAND V FRANCE, 8AM SUNDAY, CARDIFF
Gregor Paul
Objective, clinical analysis says All Blacks are ready to crank a gear and France are actually no good.
Patrick McKendry
The All Blacks should have too much firepower - and fear after their defeat eight years ago - for the French.
Wynne Gray
Time for a statement. If the All Blacks are as potent as they feel, they should smoke this ragged French side.
Nigel Yalden
We haven't seen them at their best but even a moderate All Black improvement will be good enough to defeat France in a combative, niggly encounter
Dylan Cleaver
It can't happen again... It just can't.
Elliott Smith
The French might have been able to rally in the past for games like this and while they'll be better than they were against Ireland, New Zealand are too good especially with the injection of Williams from the bench.
IRELAND V ARGENTINA, 1AM SUNDAY, CARDIFF
Gregor Paul
The Irish have been ravaged by injury but it wouldn't matter - Argentina are the better team and are capable of playing the better rugby.
Patrick McKendry
The upset of the round - the Pumas are perfectly placed to take advantage of the exhaustion of an Ireland team who played their final against France last weekend.
Wynne Gray
Lost topline talent but have been through this sort of trauma before and if hold up in setpiece will sneak in.
Nigel Yalden
Ireland to jump out to an early lead then defend like spartans to eek out a close win.
Dylan Cleaver
I don't have any conviction behind this other than surely it's time for Ireland to make the semis.
Elliott Smith
This Pumas side is not as one dimensional as those of the past and Ireland's injury/suspension toll tells.
AUSTRALIA V SCOTLAND, 4AM SUNDAY, TWICKENHAM
Gregor Paul
Seems like this one should be the easiest to call - but World Cups aren't like that. Australia will win but will be forced to work for it.
Patrick McKendry
The Wallabies should be too good across the park for Scotland, but another tough test could take its toll.
Wynne Gray
Simmering strongly without any significant impact yet from a number of stars while Scots will be no more than valiant.
Nigel Yalden
Wallabies playing with too much confidence, skill and accuracy.
Dylan Cleaver
Scotland might make things tricky for the first hour, but Wallabies will pull away late.
Elliott Smith
A couple of late tries flatters the score line in the Wallabies favour with Scotland bringing more of a fight than expected.
