Peter O’Mahony savoured the “best feeling in the world” as he left question marks hanging over his international future after leading Ireland to Guinness Six Nations glory.

Andy Farrell’s men ignited the St Patrick’s weekend party by retaining the title thanks to a a nervy 17-13 success over Scotland in Dublin.

Reports emerged before the game that captain O’Mahony was set to call time on his international career following a 105th and final outing in the green jersey.

The 34-year-old, who lifted the championship trophy with Tadhg Furlong, is “still loving” life at Test level but concedes he has a big decision to make.

“I won’t be making any decisions over the next few days,” he said. “But next week we’ll have to have a chat.

“I’m still loving it. This part of it is the best feeling in the world and that’s the part you chase.

“But you have to have a proper chat and be realistic.

“If it was my last one, it wasn’t a bad one to go out on. I can hang the jersey in a good place, if it was. But I’ll have that chat next week.

“It means the world to me (playing for Ireland).

“It’s a special thing to be picked for your country and you’ve got to treat it with the utmost respect.”

Tries from Dan Sheehan and Andrew Porter, plus seven points from Jack Crowley, helped Ireland bounce back from having their dream of back-to-back Grand Slams dashed by England last weekend.

Veteran Munster flanker O’Mahony overcame pre-match nerves to claim the fifth – and most satisfying – Six Nations title of a Test career which began in 2012.

He opted to share the trophy lift with Furlong following the death of the Leinster prop’s father James in December.

“It was a nice moment for him and his family and I thought it was appropriate –  he’s had a tough, tough few months,” said O’Mahony.

“I think this was probably the most special (of the five titles).

“We didn’t want to lose last week. But we knew we needed to get back on the horse and put in a better performance and coming back home, championship on the line, the whole lot, it was an important game for us.

“I felt the pressure, I felt the nerves and I knew it needed to be a big day for us.

“I was saying to Andy (Farrell) on the way in there, it was a tough week and it was probably one of the toughest days nerves-wise beforehand.

“It 100 per cent has to be up there with one of the most special days of my career, if not the most.”

Head coach Farrell, whose side led just 7-6 at half-time, said: “That was a proper Test match.

“Scotland are a great side. I thought they were tenacious, I thought they were tough.

“I actually thought we played bloody well. We came out of the blocks in the second half, that was magnificent – the power, the pace we put into the game.”

Finn Russell believes Scotland must improve significantly from a mental perspective after their quest for a first Triple Crown since 1990 fell short against “probably the best team in the world”.

Fly-half Russell was encouraged by his country’s dogged display at the Aviva Stadium but was left to rue frustrating inconsistency which resulted in three tournament defeats from five fixtures.

Asked if Scotland are progressing or regressing, the co-captain replied: “Today we are progressing.

“That mentality we had today and that cohesiveness, especially in defence, was brilliant.

“But throughout the campaign we need to get mentally stronger. We need to get better and put in performances week in, week out.

“We’ve had spells in this competition that we’ve been brilliant but at the same time we’ve had spells where we’ve allowed teams to get on the front foot and get momentum.

“We are progressing and it’s tough only winning two games and saying we’re progressing but this campaign will make us better come the summer, then November and next season’s Six Nations.

“From a personal opinion, I think mentally we need to get a lot better and not drift at moments in the game.

“We need to be in every moment of the game and that’s a big work on for us.

“Today, we were there for probably 90 per cent of the game, just a couple of moments that allowed Ireland into it. And, probably the best team in the world, you can’t do that over here.”

Peter O’Mahony said leading Ireland to the Guinness Six Nations title is “not a bad one to go out on” as he left question marks surrounding his international future.

Andy Farrell’s side retained the championship crown thanks to Saturday’s scrappy 17-13 success over Scotland in Dublin.

Reports emerged before the game that veteran Munster flanker O’Mahony was set to call time on his Test career following a 105th and final outing in the green jersey.

The 34-year-old, who made his Test debut in 2012, intends to take time before making a decision after helping his country bounce back from last week’s loss to England to celebrate St Patrick’s weekend in style.

Asked about his future, O’Mahony told ITV: “I don’t know. I have a few chats to have with family and stuff the next couple of weeks and if it was my last one it’s not a bad one to go out on.

“(It’s been) one of the tougher weeks of my career for lots of different reasons.

“We weren’t happy with the performance last week when we knew we could do better but we had a job to go and do and thankfully today we went out and did it against a seriously good Scottish side.

“I thought we showed loads of grit, I thought we showed ambition with the ball, in a damp, greasy environment and thought we played some good rugby and that middle 20 in the second half was massive for us.

“We spoke (at half-time) about getting stuck in and we probably put a lot of lead in their legs, so we needed to get some reward for it.

“We just said we’d stay at it and keep going and I thought the 10 minutes after half-time were really, really impressive.”

Ireland ended a sluggish first half 7-6 ahead thanks to Dan Sheehan’s opportunistic touch down, converted by Jack Crowley.

Andy Farrell’s men improved markedly in the second period and completed the job through Andrew Porter’s try and five further points from fly-half Crowley.

Huw Jones’ late consolation try, combined with eight points from Finn Russell, ensured a nervy final couple of minutes at the Aviva Stadium.

Ireland became back-to-back Guinness Six Nations champions by crushing Scotland’s quest for a first Triple Crown in 34 years with a scrappy 17-13 win.

Andy Farrell’s hosts were well below their free-flowing best in Dublin but avoided any major ‘Super Saturday’ drama to retain the championship title.

Andrew Porter’s second-half try fatally broke the resistance of the stubborn Scots to ignite the St Patrick’s weekend celebrations and satisfy an expectant capacity crowd at the Aviva Stadium.

Hooker Dan Sheehan set Ireland on course for glory – and a 10th successive win over Scotland – with an opportunistic first-half score, while Jack Crowley kicked seven points.

A pair of first-half Finn Russell penalties meant Gregor Townsend’s men trailed just 7-6 at the break and he added a late conversion following Huw Jones’ consolation try.

Yet the Scots were powerless to prevent Ireland bouncing back from the disappointment of their dream of successive Grand Slams being agonisingly ended by England last weekend.

Underdogs Scotland crossed the Irish Sea with a slender chance of snatching the title but realistically seeking to secure a first Triple Crown since 1990 following a chastening round-four loss to Italy.

Their mission to rip up the script began in positive fashion thanks to an early Russell penalty before Sheehan was gifted his fifth try of the tournament by George Turner’s overthrown lineout.

The fortunate 13th-minute score, converted by Crowley, did little to settle Irish nerves and the fired-up Scots kept up the pressure with another three points from Russell’s boot.

Farrell’s men were struggling to gain meaningful territory during a cagey opening period punctuated with errors and frequent kicking exchanges amid a subdued atmosphere.

Crowley squandered a long-range penalty to stretch the slender advantage as resolute Scotland remained relatively untroubled, while offering a threat on the counter attack.

Ireland, who had been forced to replace injured full-back Hugo Keenan with Jordan Larmour just before kick-off, trudged down the tunnel leading by only a single point and with major room for improvement.

Scotland head coach Townsend acknowledged pre-match that his side needed to produce “something special” to spoil the Irish party and bounce back from a dismal display in Rome.

Crowley made their uphill task slightly harder with a straightforward penalty before the visitors received a major reprieve when Tadhg Furlong’s apparent touch down was chalked off following a lengthy review as referee Matthew Carley deemed the ball had been dislodged.

Heroic last-ditch defending was the only thing preventing a rampant home side showing renewed purpose from fully taking control of the contest.

Scotland flanker Andy Christie superbly halted the weaving Calvin Nash with the try line in touching distance before rusty Ireland replacement Garry Ringrose inexplicably fumbled.

Ringrose, making his first appearance of the tournament following a shoulder injury, atoned with a lung-busting intercept run which led to Ireland’s crucial second try.

Robbie Henshaw was adjudged to have been held up on the line in the immediate aftermath before Porter subsequently powered over from a tap-and-go penalty following a yellow card for Ewan Ashman.

Supporters responded with a rousing rendition of the Fields of Athenry, fully believing the job was done.

However, home fans were forced to endure a nervy final couple of minutes after replacement fly-half Harry Byrne was sin binned for a head-on-head challenge on Russell and Scotland centre Jones broke clear to touch down.

Ireland duly avoided any further issues to jubilantly celebrate a fifth championship title in 11 years – and sixth overall – to underline their status as the northern hemisphere’s leading nation.

Ireland have stuck with the starting XV narrowly beaten by England for Saturday’s Guinness Six Nations title decider against Scotland in Dublin.

Andy Farrell’s men will retain the championship crown by avoiding defeat or securing two losing bonus points against the Scots at the Aviva Stadium.

Calvin Nash has overcome the head knock which forced him off inside five minutes of the last-gasp 23-22 loss at Twickenham to retain his place on the right wing.

Garry Ringrose, who is yet to feature in this year’s championship following a shoulder issue, is named among the replacements.

Farrell’s bench shows a five-three split of forwards and backs after the six-two selection in south-west London backfired because of head injuries suffered by Nash and his replacement Ciaran Frawley.

Versatile back Frawley drops out of the 23, replaced by fly-half Harry Byrne, while lock Iain Henderson makes way to accommodate the returning Ringrose.

Although Ireland’s pursuit of successive Grand Slams was ruined last weekend, they remain in a strong position at the top of the championship table, having racked up four bonus points and a vastly-superior points difference on each of their rivals.

A defeat without any bonus points could also be sufficient for the title, but would be dependent on the result of England’s trip to France in the final match of ‘Super Saturday’.

Gregor Townsend’s Scots are also mathematically still in the mix. However, following a shock loss to Italy, securing the Triple Crown looks to be the extent of their realistic ambitions.

Leinster trio Andrew Porter, Dan Sheehan and Tadhg Furlong once again pack down in Ireland’s front row, ahead of locks Joe McCarthy and Tadhg Beirne.

Captain Peter O’Mahony retains the blindside flanker role, despite his costly second-half yellow card against England and strong competition from Ryan Baird, with Josh van der Flier at openside and Caelan Doris lining up at number eight.

Jamison Gibson-Park and Jack Crowley continue as the half-back pairing, while Bundee Aki partners Robbie Henshaw in midfield.

Left wing James Lowe, who claimed Ireland’s two tries at Twickenham, and full-back Hugo Keenan complete the starting line-up.

Ireland have won 13 of the last 14 meetings with Scotland, including nine in a row following a decisive 36-14 pool-stage success at last year’s Rugby World Cup in France.

Ronan Kelleher, Cian Healy, Finlay Bealham, Baird, Jack Conan and Conor Murray join Byrne and Ringrose on the bench.
