Lovely stuff all round.

Peter O'Mahony was looking extremely emotional the entire way through Ireland's Call. He had to wipe the tears away and there was several pats from his team-mates.

Flower of Scotland was sung with as much gusto as you would expect. It's a huge day for the visitors.

That has set us up nicely. Now it's over to Ireland and the sold-out Dublin crowd.

Scotland head coach Gregor Townsend has been talking to ITV before kick-off:

"It's the players on the field that decide how well you play. There's only so much influence you can have as a coach.

"We have to be very physical and conditions aren't great today but slowing down Ireland's ball is key. Against the best team in the world you have to get it right.

"We believe in this squad. Our focus is giving a better performance than last week."

The atmosphere is great here at the Aviva Stadium and the pitch looks fantastic. It’s all set for a great game.

Ireland will want to put things right from the England game. They know they will have to defend better because they’re going to be challenged against a good Scotland attack.

Here come the teams!

Tadhg Beirne leads the way on his landmark 50th cap for Ireland.

Peter O'Mahony and Finn Russell lead out the rest of the packs.

There's some noise in Dublin. It's time for the anthems.

Should bonus points be in the Six Nations? BBC rugby union correspondent Chris Jones has his say on BBC Radio 5 Live:

"It is nothing to do with England. It is to do with the fact it is nonsense if someone wins the title with three wins and someone finishes second with four. Let's hope that doesn't happen.

“There was always the fear that bonus points were going to be a bad idea at some point, but there are plenty of examples where bonus points have helped teams keep playing. Ireland against Wales is a good example - teams going for a fourth try to keep the game alive.

“I see why they are in but I don't think they should be in the Six Nations. Let's hope there isn't a scenario where Ireland are 10 points down and kick a penalty to lose by seven to get a losing bonus point to win the title. That would just feel wrong.

“The great thing about the Six Nations is winning and losing. If you win 12-10 no one walks away thinking you should have got the bonus point.”

Ireland will retain the title if they win or draw against Scotland in Dublin.

If Ireland lose but secure a bonus point - for scoring four tries or finishing within seven points of Scotland - they will most likely clinch the title given their vastly superior points difference.

An Ireland defeat without a bonus point should still be enough if England win without a bonus point.

England will be crowned champions if they win with a bonus point and Ireland fail to collect a point. Scotland need to win with a bonus point, deny Ireland a point and overturn Ireland's huge points difference advantage to have any chance.

They then need France to beat England without a bonus point or with a bonus-point win by a smaller margin.

Ireland head coach Andy Farrell has been talking to ITV before kick-off:

"I want to see us committing fully and attacking.

"It's a final for us and we need to be on it from the start.

"The opposition we've got are top draw. They've got the ability to play well and get on the front foot."

Here's the updated table after Italy's win over Wales.

Italy could move up to third without passing another ball if France and Scotland are on the end of heavy defeats.

Still some effort. They've really stepped up this year.

Ireland's task hasn't changed, however. Win or draw and it's done.

Defeat and things get a little more complicated.

Irish fans will be hoping Hugo Keenan's 11th-hour withdrawal isn't a sign of things to come.

Keenan is pivotal to this Irish team, although they did cope without him against Wales with Ciaran Frawley ably deputising for his Leinster team-mate.

It's a big day for Jordan Larmour, though. His late cameo against Italy a few weeks back was his first cap in three years.

There has to be a response.

Scotland will be an angry team after the Italy defeat. They shouldn't lack in aggression and motivation, it's just whether they can live with this Ireland team.

Can they stay in the game long enough for Ireland to get a bit jittery?

Head coach Gregor Townsend knows Scotland need "something special" to topple Ireland in Dublin on Saturday.

A draw is enough to clinch back-to-back Six Nations titles for the hosts, who seek a 10th straight win over Scotland.

The Scots' last away win over Ireland came in 2010.

"We need to deliver our best performance this season to come away with a positive result," said Townsend, who makes two changes to his starting XV after defeat to Italy in Rome.

"We know how tough it's going to be. They are one of the top two teams in the world at home where they have been virtually unbeatable over the last few years.

"It's going to require something special but we believe in the players.

"The frustration is that we are not going to Dublin with four wins. We feel we had a win taken away from us against France and we could have been better against Italy."

Here's more from Peter O'Mahony on that mad final day from 2015.

"That was the mad day, wasn't it? Yeah, it was torture," said O'Mahony, recalling the anxious wait.

"Wales went out and put up a big score, then we did the job and then it was pure carnage the last game.

"I'm sure it was a great watch for the rest of the world. I remember watching it from the stairwell in Murrayfield, praying to God, so, look, that's what the Super Saturday means for the competition.

"It's great that there are so many teams involved that can win it."

For Ireland, the equation is much simpler this time. They will retain the title with a win or draw against Scotland. If they lose but secure a bonus point, they are still more than likely to win the title given their vastly superior points difference.

"Torture", "pure carnage", hanging around in a stairwell watching another game and praying that someone else doesn't steal the title.

These are all things Peter O'Mahony hopes to avoid on his first 'Super Saturday' as Ireland captain.

This weekend's Six Nations conclusion stirs memories of 2015. The similarities are indeed striking.

Nine years ago, Ireland retained the title. They did so after playing Scotland and after England faced France in the tournament closer. An identical sequence of events could unfold this weekend.

In 2015, England led Ireland on points difference going into the final day with Wales in third. Wales' thumping 61-20 win over Italy in Rome meant that Ireland needed to beat Scotland by 21 points to top the table.

The Irish were duly up to the task and hammered Scotland 40-10 at Murrayfield. It wasn't enough to win the title on the spot, though. England faced France knowing a 26-point win would be enough, but despite building a 55-35 lead and pressing the French line, they came up agonisingly short.

If Ireland are to win this Championship, they're going to have to work extremely hard to do it. We've already seen an upset today with Italy winning in Cardiff.

As a Scotsman I am cautious but if we can get points on the board then you never know.

There's a late, enforced change for Ireland.

Hugo Keenan is out with a hip injury and Jordan Larmour comes into the starting side at full-back.

That's a big blow ahead of kick-off.

It is St Patrick's weekend after all, it would be rude not to post these.

In Dublin on Saturday, Scotland can beat Ireland for the first time since 2017, in the Irish capital for the first time since 2010, a first Triple Crown since 1990. They can finish first, second, third, fourth or fifth depending on results. Triumph or despair? Given the history, the smart money is on despair.

Some Irish rugby observers like to portray the Scots as popinjays, all mouth and no action, constantly talking themselves up. This kind of stuff has been going on for years and it's been groundless in the most part, a bizarre distortion of reality.

On the face of it, this looks like Scottish chutzpah, but maybe it's more to do with Scottish insecurity. Heading to the Aviva on Saturday, they have nine defeats in a row against Ireland. The average try count across those nine Tests is 3-1 in Ireland's favour, the average score 26-11. One team has a firm psychological hold over the other.

Townsend said on Thursday his team would need to score 20 points - and possibly more - to win. They have managed 20 points against Ireland once in nine attempts, single figures on four occasions.

Irish hooker Dan Sheehan has been talking to ITV before kick-off:

"It stings losing a game you're expected to win. We are going to take a few lessons from it, it was a tough review. It's going back to basics, the trust element.

"I loved the way Keith Wood played and scoring off the back of line-out. Rory Best as well. It's big shoes to fill. Something I grew up loving was attacking rugby. Sometimes I feel I need to focus more on the traditional set-piece side of rugby as well.

"Scotland are a changing team and will be hungry for a win. You've got them coming over to spoil the party and a chance to win."
