It's very messy at the moment!

Argentina will the line-out but Dillon Lewis wrestles the ball back in a tackle.

A bit of kick-tennis begins between both sides, which eventually leads to another Argentinian line-out, just inside their own 10-metre line.

The scrum goes down but Wales have the ball and clear their lines.

Argentina follow suit by kicking the ball straight back to Wales, and Rio Dyer tries to break a tackle but his offload is collected by Jeronimo de la Fuente.

Wales are penalised yet again, this time for a high tackle by George North, and Argentina kick to just outside the Welsh 22.

That's six penalties already against Wales if you haven't been counting.

Argentina look comfortable here.

There is a slight break in play as Dan Lydiate receives a bit of attention from the medical staff, he looks like he will be okay to continue though.

Wales are finally having a bit of possession, but Gareth Anscombe's cross-field kick goes about a metre forward and Argentina collect the ball.

The Pumas then opt for a kick of their own, into Welsh territory, but Mateo Carreras just knocks the ball on and Wales will have the put-in at the scrum.

Boffelli can kick from wherever on the pitch. They are a clinical side, that's why they've gone for the kick.

Emiliano Boffelli had eight successful kicks at goal against England last week, he's well on his way to that mark again today.

They thoroughly deserve this early lead.

Discipline is a real issue for Wales so far in this opening quarter of an hour, and referee Ben O'Keeffe wants a word with Wales captain Justin Tipuric.

Wales are already on their last warning, next offside in their own 22 will be a yellow card.

This time Argentina point to the posts.

It's all Argentina at the moment, and they're into the Welsh 22 once again.

Advantage is being played as they attempt a grubber kick through to Mateo Carreras but Louis Rees-Zammit sees that out of bounds.

We come back to the penalty, which this time is kicked to the corner.

Argentina looking to strike while momentum is behind them.

Discipline will indeed be important, and right on cue Wales are again in the referee's bad books.

Louis Rees-Zammit collects a high ball but Rio Dyer is adjudged to have blocked the Argentinian wing Mateo Carreras from catching the ball.

It has been a much more upbeat start from Wales this week following breaks from Louis Rees-Zammit and Rio Dyer.

Argentina have weathered the early storm just as they did last weekend in the 30-29 win against England at Twickenham.

What's going to be important for Wales is discipline.

An early lead for the Pumas.

Argentina look to get the driving maul going before releasing the backs, full-back Juan Cruz Mallia makes a few metres before Wales are penalised again, this time for not rolling away.

Santiago Carreras points to the posts, a chance to open the scoring for the Pumas.

George North knocks the ball on midway into the Argentinian half before Wales are penalised for being offside.

A chance for the visitors to clear, which they do up to half way for their first line-out of the game.

Argentina just about retain possession at the scrum before clearing up to Rio Dyer on halfway.

He skips along the touchline and Wales are just outside the 22 with ball in hand once again.

Perfect start for Wales!

Louis Rees-Zammit, switched to full-back this afternoon, breaks two tackles and bursts into the Argentina half.

He offloads to George North who in turn finds Taulupe Faletau but the ball is knocked on by Wales just inside in the Argentinian 22.

Time for the first scrum of the match.
