Quotes corner
Leinster's Robbie Henshaw: "I last played in an empty stadium at Buccaneers down in Athlone in an under-20 game.
"We've all been talking about it, but it's about being mentally ready and doing it in training - repping match intensity at training in an empty stadium.
"It's about trying to get a match atmosphere, so that we'll be ready to go.
"We've had a couple of referees come in and ref our stadium, we've been in the RDS training in front of empty seats to replicate playing in the Aviva.
"It will be strange being in a huge stadium with empty seats, but it's kind of the mental side of it as well and how you can get yourself ready for it."
Munster's Peter O'Mahony: "I can't imagine it will be anywhere normal with regard to the atmosphere and that type of thing, it's going to be very strange.
"But I'm just glad we're back playing rugby, to be honest with you and whatever it takes to do that, we're prepared to combat it.
"It's for both teams, both sides are going to have to deal with that aspect of it. It's going to be different but we're going to have to battle on with it."
