'Torture' of 2015 gives Peter O'Mahony singular focus as Ireland bid for Six Nations title

It was no surprise that Peter O'Mahony has set his sights on beating Scotland but the Ireland captain says the senior players are aware of the permutations that would clinch the Guinness Six Nations title.

Ireland have a four-point buffer over England going into the final round.

Their vastly superior points difference means a single match point would be a de facto title-clincher and two points would give them an unassailable lead, no matter if England managed to reach 17 with a bonus-point win in France.

The unthinkable scenario would see Ireland lose without a bonus point and then have to hang around the Aviva Stadium as Scotland celebrate a Triple Crown while cheering on France in Lyon.

A win takes everything else off the table and the celebrations can begin in Dublin as Les Bleus and England play out a dead rubber.

"You have to discuss these things, especially the guys who are making decisions around refereeing calls, that kind of stuff, penalties," O’Mahony, who will captain the side on his 105th Ireland appearance, told RTÉ Sport.

"We are going out to win tomorrow, that’s what we do for every Test match.

"Of course, there’s a handful of us who might have to make a decision or need to know the permutations, but we want to put in a performance tomorrow that’s capable of winning."

The last day of the championship in 2015 brought with it no end of Super Saturday drama.

Wales thrashed Italy to move ahead in the table, Ireland beat Scotland convincingly in Murrayfield leaving England needing a 26-point win over France in the final game.

"The mad day, was it?" O’Mahony said when asked for his memories of their last back-to-back title wins, clinched when England, despite France’s best efforts late on, won by 20.

"It was torture,"
