Wales' exits were a problem the whole of last weekend against New Zealand, and they have made another mistake here.

George North fails to collect the kick-off handing momentum straight back to Argentina.

Luckily for Wales they win back possession and clear.

Wales have been rewarded finally for patience in the attacking phase play.

Centres Nick Tompkins and George North and number eight Taulupe Faletau have given Wales the go-forward needed to get over the gain line with some charging runs.

Gareth Anscombe slots home the reasonably straightforward penalty and Wales' lead extends to four points.

Birthday boy Taulupe Faletau does excellently to catch a pass behind him from Justin Tipuric to keep the Welsh attack going.

Argentina are then penalised for tackling George North in the air and this time Wales point to the posts.

That's a way to respond, a very happy birthday to Taulupe Faletau getting the first try of the game and it's exactly what we needed.

Argentina's restart from Santiago Carreras goes straight into touch and Wales get the put-in on halfway.

They are right back on the front foot.

They are causing problems here for Argentina when they get the ball, they just need to be more clinical.

Jac Morgan is more powerful than he was last season.

Wales are into Argentina's 22 and they have a penalty coming for another offside against the Pumas.

They are pushed back a few metres after Louis Rees-Zammit spills the ball backwards so we will go back to the penalty.

Wales are penalised at the scrum this time and Argentina clear up to their own 22-yard line.

The Puma's knock on at the line-out though and Wales are handed possession straight back.

Dan Lydiate's game is over as he is replaced by Ospreys' Jac Morgan.

Looks like that knock picked up earlier was still troubling him and the flanker goes off clutching his wrist.

It was very good defending by Argentina.

Reading the play well.

The Principality Stadium cheers as they think Wales have scored the game's first try, but Ken Owens spills the ball forward as he dives over to score.

The experienced hooker will be disappointed with that.

This is better from Wales, but they still seem a bit sloppy in attack.

They are improving though.

Wales make a hash of the line-out and Argentina clear.

It will be a Welsh line-out midway into the Puma's half.

The Welsh driving maul looks set to cross before collapsing under its own weight.

Argentina are then penalised for offside, just as Mateo Carreras intercepts a pass with the whole field in front of him.

We go back to the penalty.

The Welsh scrum does its job and they have a penalty coming for an infringement.

Referee Ben O'Keeffe lets a few phases pass before going back to the penalty, which Gareth Anscombe sends into the corner.

Argentina make their first mistake of the game. Gonzalo Bertanou fumbles the ball forward out of a ruck and Wales will have an attacking opportunity from the scrum.

Discipline is again a problem for Wales in the opening quarter with six penalties conceded.

It is just stopping any momentum Wales might have and shows the pressure Argentina are being allowed to exert.
