South Africa are enjoying the lion's share of possession so far, but are yet to really test the Welsh.

Conor Murray gets in and over and earns the first penalty after only 40 seconds. 

Paddy Jackson kicks to the corner for Ireland. A nice, clean line-out ensues and the hosts try to push past Australia's defence.

A huge roar around the Aviva Stadium as Ireland's Paddy Jackson get us under way. Cracking atmosphere in Ireland's capital. 

Romain Poite blows his whistle and Dan Biggar gets us under way with the kick-off.

Anthems have been sung, pleasantries with VIPs exchanged. 

It's almost time for kick-off in the second round of Saturday's autumn internationals.

Wales coach Rob Howley: "I have loved every minute. We haven't found our rhythm in this series and it is important to find that today. 

"The players have been fantastic and it is about trying to transfer training into the stadium.

"We have focused on ourselves this week. As players and coaches anyone has the ability to beat anyone on their day.

"It is critical we get the win and performance today. We can't afford to keep hurting ourselves. We want to play an offloading game but it is about the decision making process to go along with that."

South Africa's under-pressure coach Allister Coetzee: "It is tough to be coach, you never imagine taking job and it be as tough as it is. 

"It is has been a tough couple years and this year hasn't helped but it is time to act. 

"It is the start of a new era. I am excited to see how they go tonight."

Eddie Butler
BBC Rugby commentator

Never have twin victories in November - never traditionally Wales' most bountiful month - been greeted with such lack of warmth.

"The performance against Australia was chilly and the mercury hasn't risen with wins over Argentina and Japan.

"Never have South Africa stared at eight defeats in a calendar year. Frosty doesn't begin to describe the reaction back home, external to the Springbok tour.

"There is ice around Wales-South Africa, in stark contrast to the glow that envelops England and the fieriness of the Ireland-New Zealand mini-series. No more. Stand by to discard your thermals. The final game of November in Cardiff is going to be hot - perhaps more friction burns than fires of invention, but there is no way this is going to be anything other than hot-blooded.

"Why? Not sure, but it probably has something to do with physics and the build-up of pressure. It doesn't matter. The cold spell is over. Three wins would be positively sunny for Wales.

Australia coach Michael Cheika has made nine changes from last weekend's narrow win over France, as he recalls skipper Stephen Moore and other big-name players Israel Folau, Sekope Kepu, Rory Arnold, Michael Hooper, and Dane Haylett-Petty  

Dean Mumm is preferred to Lopeti Timani in the back row.

It’s a cold day in Cardiff, the weather echoing the chill blowing through the ranks of the Wales and South African squads.

The Springboks are the team in real disarray, on the brink of an unprecedented eight defeats in a calendar year. Wales have won their last two matches – but you wouldn’t believe that if you read the coverage of their 33-30 defeat of Japan.

Performance or result? Both, was Wales interim coach Rob Howley’s answer this week.

The suspicion is he would take the win first. His opposite number Allister Coetzee definitely would.

Wales skipper Sam Warburton misses the match after he was injured in training.

Apart from Dan Lydiate replacing Warburton, head coach Rob Howley has opted to return to the side that beat Argentina two weeks ago.

South Africa have dropped iconic winger Bryan Habana.

Debutant Jamba Ulengo replaces Habana, while centre Rohan Janse van Rensburg and back-row Uzair Cassiem also win their first caps.

The heat is on both teams today at the Principality Stadium.

Wales have stuttered their way through the autumn internationals, while South Africa arrive after last week's harrowing defeat to Italy as they dropped out of the world's top four for the first time in a decade,

The 2007 World Champions have lost six of their last seven.

Both teams desperately need a win today.

BBC Two

If you want to watch Wales v South Africa, then put BBC Two on now.

So far we have had a Scotland try-fest and a hard fought England victory.

Enjoyed it?

How about some more? In just over half an hour we have Wales v South Africa and Ireland v Australia.

You have just enough time to grab a brew, or perhaps something stronger, and join us for a cracking teatime of international rugby.

England coach Eddie Jones on Sky Sports: "Our team was brilliant today. The way we adapted our tactics and coped with the problems was tremendous and the senior players were outstanding.

"The referee was busy. He made his decisions, and they are always tough.

"Elliot's tackle was an error of judgement. The boys will support him and he'll be fine.

"I think we won the match before half-time. The way we held on with those scrums was superb. It was 15 men against 13 of a rugby league team but we coped."

Scotland's man of the match Ryan Wilson: "It was hard work. We knew how tough it would be. It is great to get the win in front of a great crowd. 

"In the first games against Australia and Argentina it was so tight but things started to come together today. 

"We have plenty more to work on but plenty to take into a massive Six Nations."
