Wales have their first attacking opportunity with a lineout just outside the Ireland 22.

But after a neat set-piece move the hosts steal possession and win a penalty with Sexton clearing the Irish lines.

Ireland are using one-out runners.

And Wales are one of the best sides in the world at getting players over the ball if you stay isolated.

They've been turned over twice in the 22, but already this is much better in attack from Ireland.

They're putting width on the ball and giving their dangerous runners a chance to really get involved. We hardly saw any of wingers Stockdale and Conway last week, looks like they'll be right in the thick of it today.

Wales have not been in this game so far but defensively they have been superb in the contact area.

They have achieved a turnover penalty while the outstanding Justin Tipuric has just held up the Irish maul to gain Wales a scrum.

Wales have been absolutely superb in the contact area.

They've turned over Ireland once in the scrum and won a crucial turnover there.

Ireland seem to think they can gain some success down the Wales right hand wing with a lot of the attacks based there so far.

But Wales win a turnover penalty and clear their lines again.

Wyn Jones will be very happy with that.

Four scrum penalties against him last week so that's a big confidence boost for him.

Ireland are the first to impress with a flowing move down the left-hand side as Dan Biggar is forced to ground a Jacob Stockdale kick over the Wales line.

Ireland have an attacking scrum but Wales claim the all important first penalty at the set-piece.

French referee Romain Poite blows the whistle to officially start the second round of Six Nations matches. Ireland captain Jonathan Sexton kicks off to Wales.

Storm Ciara is brewing this weekend but there is no evidence of any extreme weather at the moment at the Aviva Stadium although it is a little blustery.

Ireland and Wales will both be looking to build on victories in the opening round. So we should have an intriguing contest in Dublin this afternoon.

I'm expecting to still still some of that creative flair from Wales.

I anticipate them bringing confidence from the Italy game.

French referee Romain Poite will be in charge at the Aviva Stadium today.

He will be assisted by touch judges Luke Pearce (England) & Mike Fraser (New Zealand) with New Zealander Glenn Newman on Television Match Official duties.

Ireland are definitely coming up against a better side this week.

They know they have a really stern task on their hands and this game will start fast and hard.

Ireland have an impressive record in recent seasons.

• Ireland have won their second Six Nations match in five of the last six campaigns.
• Andy Farrell's side won 10 turnovers against Scotland, twice as many as any other side during the opening weekend.
• They have won 70% of their matches at the Aviva Stadium since it opened in 2010 (W35, D2, L13).
• England are the only visiting side to win in Dublin in the last seven Six Nations tournaments, doing so in 2013 as well as last year.
• Ireland have won 16 out of their 17 matches on home soil with the exception being last year's 32-20 defeat by England.

They always say we should keep politics out of sport, and maybe they're right, but that isn't going to happen in Dublin today.

There's a buzz around the capital as the Republic of Ireland goes to the polls in a General Election, but as you drift out to the east of the city that buzz soon becomes a sea of green containing a few sizeable pockets of red.

Not political colours, but certainly partisan, and what both of these sides know that this is a huge game in the Six Nations.

From an Irish perspective, they're likely going to need to produce their best performance since their opening World Cup win over Scotland on 22 September if they are going to beat Wales, who know a win today would set down a huge marker as they seek back-to-back Grand Slam.

We know this for sure: Ireland need to step it up a gear today after a lukewarm opening last week.

We eagerly await the result (s).

I don't want to sound rude, yes it was an impressive scoreline last week, but Italy weren't very good.

We haven't seen what Wayne Pivac's Wales can do yet.

This is their first challenge today.

Fly-half Dan Biggar says his side aim to make life "uncomfortable" for opposite number Jonathan Sexton in Dublin.

New captain Sexton scored all of Ireland's points in the 19-12 win over Scotland in the opening round.

"I suppose it is up to us on Saturday to try and make life as uncomfortable for him as possible," said Biggar.

"If we give him a free ride and let him dictate play, we have seen over the years how good a player Johnny is."

Storm Ciara is not causing chaos, not yet anyway.

That said, it is pretty windy in Dublin, easily enough to add a extra layer of jeopardy to the kicking game of both sides, but not enough to cause carnage.

Conor Murray will make his 80th international appearance today, and during his eight and a half years in the team he has taken Ireland's box kicking game to new heights.

By his own lofty standards he was way off the mark in that regard last week, and it will be interesting to see a if combination of last week's difficulty and a pretty windy day impacts how frequently Murray and Ireland employ the box kick today.

Ireland scrum coach John Fogarty insists Andy Farrell's side are prepared for the double onslaught of Wales and Storm Ciara.

Saturday's Six Nations match against the Grand Slam champions in Dublin is forecast to be played in heavy rain and gusty conditions.

"We've put some scenarios in during the week so that we're adaptable tomorrow," said Fogarty.

"We've had a good week and we feel we are ready for Storm Ciara and Wales."
