Ireland wing Simon Zebo believes it will be a "huge test" against Wales when the two nations collide at the Millennium Stadium on Saturday, March 14.
Joe Schmidt's side are now two games away from a Grand Slam after beating England on Sunday, with trips to Wales and Scotland their Six Nations run-in.
And wing Zebo is under no illusions at how difficult the task in Cardiff will be next Saturday, sighting the Welshmen's ability to attack from anywhere.
"It's a huge test, Wales on their day can beat anyone. They are an unbelievably dangerous side, and that will be the massive focus for us now. It's the biggest game of our season and we've got to do everything we can to prepare as best we can," he told Irish Rugby on Monday.
Their two away games are set to be testing affairs, especially with Wales having bounced back from their opening round defeat to England while Scotland will be wounded following losses to France, Wales and Italy, something Zebo is wary of.
"We can't think like that (about the clean sweep), we've just got to focus on Wales," he said.
"If you look too far ahead of yourself you'll slip up. So we're just focused on preparation now, trying to recover and regroup, and put our best foot forward for Wales. I don't think so to be honest, no, it doesn't ever feel like that (that it's hard to keep Grand Slam thoughts to one side).
"Each day there's something new in training, we're kinda in a bubble and we don't really get wind of these exterior things that would be whispered about. We're just constantly trying to improve and constantly training, with meetings and everything we don't get a chance to think about these kind of things, so we'll just be focused on Wales."
