Argentina are threatening here, Liam Williams with a crucial tackle.

Matt Dawson
Former England scrum-half on BBC Radio 5 Live
Tight and precise form Wales off the line-out crashing it up the middle. No room for error when you give it to George North on the charge. Really well recycled from Wales.
Lovely variety from Wales early on.
Wales 0-0 Argentina
The scrum was a stalemate but full-back Juan Criz Mallia escapes the Welsh clutches up the right win
Wales 0-0 Argentina
So the game's first scrum and interestingly, of the eight quarter-finalists, Wales have the highest success rate and Argentina the worst. How times have changed!
Wales 0-0 Argentina
Nicky Robinson
Former Wales and Cardiff fly-half on BBC Radio Cymru
Nick Tompkins has played really well, taking the ball to the line and it's bringing the best out of George North as a centre.
Tompkins has played well for Saracens for years and now he's showing it for Wales as well, dominating the midfield as he does for Sarries.
Wales 0-0 Argentina
Wales win the first lineout, George North gets his first chance to truck it up midfield and Josh Adams produces a great left-hand pass to release Louis Rees-Zammit. Promising.
Wales 0-0 Argentina
Caryl James
Former Wales wing on BBC Radio Cymru
Who's going to complain when we have Jac Morgan and Tommy Reffell on the field, Reffell was superb against Georgia.
It's an incredibly dangerous combination, with Reffell over the ball and Morgan can still run his lines as he did against Australia, so a bit of a restructure but not too much difference.
Wales 0-0 Argentina
Jaco Peyper blows his whistle and Dan Biggar gets the quarter-finals under way.
Wales v Argentina (16:00 BST)
Referee Jaco Peyper also did the last World Cup quarter-final for Wales - when they beat France in Japan in 2019.
He sent off the French lock Sebastien Vahaamahina for elbowing Aaron Wainwright and got in trouble after the game when he was pictured with Welsh fans recreating the elbow incident in a bar that night.

Wales v Argentina (16:00 BST)
I don't know if this helps Wales fans or is just tempting fate... but Argentina have only beaten Wales once in the last seven meetings - and only twice in the last 11.
Wales v Argentina (16:00 BST)
First it was Henry Thomas after thrashing Australia...
Then it was Nick Tompkins after beating Georgia.
Who will be next?
Wales v Argentina (16:00 BST)
Among the 60,000 inside Stade Marseille will be the Prince of Wales.
William, the patron of Welsh Rugby Union (WRU), will be cheering on from the stands hoping for a Wales win.
He travelled to Bordeaux last month to watch Wales beat Fiji 32-26 in their opening game, where he sat alongside Rugby World Cup director and former Wales fly-half Gareth Davies.
It is not yet known if the Prince or the Princess of Wales, who is the patron of the Rugby Football Union, are due to attend England's quarter-final match against Fiji at the same venue tomorrow.
Wales v Argentina (16:00 BST)
The talking is over, the warm-ups are done...
First, Hen Wlad Fy Nhadau.
Now Himno Nacional Argentino.
Wales v Argentina (16:00 BST)
We're now observing a moment's silence as a mark of solidarity with all those affected by the tragic events in Israel, Gaza and Arras in France.
Wales v Argentina (16:00 BST)
So earlier I asked you to name the six Wales players who had scored a World Cup hat-trick before Louis Rees-Zammit last week.
The answers are:
Anyone get all six - and opponents?

There has been plenty of grumbling over the controversial World Cup pool draw that has a distinctly lop-sided feel to it.
That is only going to increase this weekend given that two of Ireland, France, South Africa and New Zealand are going out.
However Warren Gatland has hit back at teams feeling a sense of injustice, saying they should have performed better at the last World Cup.
"It's not our fault this happened," said Gatland.
"I'd just say to the other teams they should have done better in the last World Cup, that's where the draw came from.
"You didn't hear us complaining in 2015 about Fiji, Australia and England and ourselves in the same pool.
"You're just have to deal with the hand you're dealt.
"I agree with the sentiment that the draw may have been done too early, but it's been done too early in the past.
"Whether the people in control of that next time can put the pools together a bit later, that's up to them. We can't change what's been done. All I can say, we were in control of what we're doing."
Wales v Argentina (16:00 BST)
Former Argentinian centre Marcelo Bosch on S4C: "I believe Argentina are underdogs.
"Wales arrive in good form, they finished first in their pool, and Argentina arrived without a lot of confidence.
"The first game was tough, we had some shades of good performance last week but to beat Wales we'll have to raise the level again.
"I think Argentina still haven't played at their best at this World Cup, they'll have to be very patient because Wales are very patient in their game plan, Wales always create a lot of chaos in the breakdown and are happy to play without the ball.
"Argentina like playing with the ball in hand but they have to earn the right to play with territory and winning the breakdown and hopefully we see a better version of Argentina today."

Wales fly-half on BBC Radio Cymru
Wales were very slow out of the blocks in the Six Nations and it's something they've clearly looked to improve on over the past few months.
Wales are a better team when leading than chasing the game as the tactics don't suit chasing a game.
Argentina are very passionate and the fans are as well, England managed to take all the energy out of the crowd and it's crucial Wales do that too, if they don't and the fans inspire the players it could be a very long day.
Wales v Argentina (16:00 BST)
Argentina hooker Augustin Creevy will today become the fifth oldest player to appear in a World Cup - at the grand age of 38 years and 213 days - if/when he comes off the bench.
He made his debut back in 2005 and was the first Argentina player to reach 100 caps.
Out of interest... anyone know the oldest player in World Cup history?
I won't keep you waiting on this occasion! It was another South American, former Uruguay number eight Diego Ormaechea who was 40 years and 26 days old on his final appearance in 1999.
