This is unbearable, I keep forgetting to breath.

What a tackle from Liam Williams!!!!!!!!!!!! But is it illegal?????????

Oh dear lord. Cornal Hendricks is flying into the corner and Williams takes him out with no arms, that looks illegal to me.

Referee Steve Walsh says "clearly an illegal tackle". Now he wants to know if it would have been a try. I think it would have been...

This has been a real rock opera of a match and now we're deep into the last act.

Another scrum, Wales win it just but Taulupe Faletau is swallowed up by a giant green wave and it's a penalty to South Africa which Morne Steyn sends deep into the Wales 22.

"The Welsh have got old heads too and they just need to be patient and keep their discipline because they can't give away penalties and give South Africa the chance to get that driving maul going."

Former South Africa and Leicester Tigers fly-half Derick Hougaard on BBC Radio Wales: "This is going to be a great finish to a great Test match. There are a lot of old heads in that South African team and they will know how to handle the pressure and the game of this final 10 minutes.

"Can they pull off the impossible? Wales don't deserve to lose."

This kid is a genius.

South Africa batter away, big man after big man trying to bulldoze their way over from a couple of metres, but suddenly Willie le Roux pops up in midfield and appears to teleport through Wales' previously impenetrable defensive line to score.

Morne Steyn converts, less than a converted try in it.

Andrew Lavoipierre:, external Wales deserve to be ahead. They're more hungry, simple.

Cornal Hendricks makes a slashing break from his own 22, the Boks earn an advantage and Jan Serfontein chips ahead, but Wales just scramble the ball into touch.

Martyn Williams expects his old team to close it out, and who are we to disagree?

An attack comes to a halt in the Bok 22, but it's another scrum...

"I hope it's not the commentator's curse but I really can't see South Africa coming back from this. They're all over the place.

"Wales have been totally dominant, the scrum is on top and they're controlling every facet. It's the best Welsh performance I've ever seen, particularly after last week."

Former South Africa and Leicester Tigers fly-half Derick Hougaard on BBC Radio Wales: "You can feel the people in the stands getting a little bit nervous. That's two great scrums in a row from Wales.

"Schalk Brits is on the field now. South Africa want to play a bit of rugby."

Just as there's a big five in South African game there's also a big five in world rugby - and Wales are on the verge of proving that they belong at the same table as England and the three southern hemisphere giants New Zealand, South Africa and Australia.

They win another penalty at a scrum and clear deep.

Mighty shove from Wales against the seven-man Springbok scrum.

Back march the Boks, up go their front row, Dan Biggar will go for goal and through goes th ekick.

Thirteen points, 13 minutes... history beckons.

Wales are trying to bully their way through midfield but South Africa hold firm.

The tourists have a put-in centre field on the Bok 22 - can they fashion what would surely be a match-winning try?

Former South Africa and Leicester Tigers fly-half Derick Hougaard on BBC Radio Wales: "If they can get the Springboks to start chasing this game, Wales could be about to make history."

... except you can't just try and hold on for 20 minutes, you have to keep taking the game to the opposition.

Wales have a throw on the South Africa 22 but Ken Owens' throw goes awry and South Africa clear.

Wales can't afford mistakes like that.

Jamie Roberts hammers on for Wales, but Bismarck de Plessis steals the ball for the hosts and they counter through Willie Le Roux.

Wales look stretched but when the ball is move infield to Tendai Mtawarira he knocks on. Down to 20 minutes to hold on now...

Former South Africa and Leicester Tigers fly-half Derick Hougaard on BBC Radio Wales: "I don't think Flip van der Merwe meant it but rules are rules and it was probably the right call."

And now the Boks are down to 14 men as lock Flip van der Merwe is sin-binned for taking out Alun Wyn Jones as he claimed the kick off.

Carpe diem Wales, this is your chance.

From BBC Scrum V:, external They've only gone and got a new banner! Top quality from the Bedwas 12.

No sooner than South Africa get back within a score, Gethin Jenkins wins a penalty as Victor Matfield holds on and Dan Biggar will go for goal.

Through the middle goes the ball and Wales are back out to 10 points. Astonishing.
