Wales return home after two away victories in the tournament and Rees can not wait to build on those successes and put in a strong performance in front of the famous Welsh supporters.
“The Millennium Stadiums has the X Factor and there is no better stadium to run out in anywhere in the world,” said Rees.
“It was great for us to win back-to-back games on the road as it is a tough ask in the Six Nations, but we have to kick on from the last few weeks.
“We are now up to second in the table and it’s a great place at the moment but international rugby is all about winning.
“We have to make sure we are accurate, make sure we are not turned over and our discipline has to be spot on as Ronan O’Gara has been around for a long time and is one of the best kickers in the world.
“It’s going to be tough up front but we have to concentrate on ourselves. Our scrum came under a bit of pressure out in Italy but we worked on that in the week and it’s important that we get a platform.”
