Wales v South Africa
Wales are struggling a bit now selection wise. They have lost Liam Williams, Jonathan Davies is back in and Josh Navidi is out of the back row. Warren Gatland has been forced to shuffle things around.
They were very lucky to get over France in the quarter-final and at times showed a soft underbelly when it came to defending. The French pulled them apart at times.
They may say that things are going their way, but last weekend the Springboks played as well as I have seen for a long time and stopped Japan from scoring a try, which is a hell of an achievement.
This game will be a battle of the defences. Wales' game is pretty much built on defence, and it is also an area that South Africa pride themselves on also.
South Africa are a brutally physical side and beat Japan up completely.
I can see Rassie Erasmus' side having the edge in this one.
Verdict: South Africa
New Zealand v England
I think England will really put it up to them, but I think New Zealand, after last week’s win, are in the right place.
They have made an interesting change in the back row where they have taken out Sam Cane and put in Scott Barrett because they are expecting a very physical approach from England.
Barrett has never played in the back row before, he is an out-and-out second row, so they are obviously concerned about Engand’s physicality.
England for their part have made an interesting call in midfield. They have always seemed a better attacking team with Owen Farrell at out-half. Now they have put George Ford back in there again.
England have played well with Ford at 10, but they have never been at the top of their game, but having two play-makers suggests they will move the ball around a bit more.
Both coaches are making adjustments around the opposition.
On balance, you’d feel New Zealand will win this, but having said that, England have nothing to lose. It will be the game of the weekend and I think the All Blacks will have the wherewithal to get the job done.
Verdict: New Zealand
