Ireland prop Mike Ross has stressed the desire among the team to claim a second consecutive Six Nations title for the first time since 1949.
Wales's win over Ireland last Saturday means that four teams can still win the championship going into the final weekend, with England, Ireland and Wales all locked on six points and France two further back on four.
The title is expected to be decided on points difference, and Ross believes that a big enough victory over Scotland at Murrayfield on Saturday would be a "huge lift" ahead of the World Cup later this year.
"It would be huge, it would be a huge one for us. It would certainly give us a huge lift going into the World Cup. It is something we really want as a squad," he is quoted as saying by PA.
"There was a lot of disappointment in that dressing room after that Welsh game because for some lads, when is the next opportunity going to come around for a Grand Slam again? You don't know.
"It's hugely important: it would be a great achievement for this squad if we could do that, the back-to-back championships. But at the same time we can't get ahead of ourselves, the main focus is to beat Scotland first and foremost and any number of points after that would be a bonus."
England, who currently top the standings, are at home to France on the final weekend, while Wales take on Italy. Scotland, meanwhile, will be looking to avoid the wooden spoon against the Irish.
