Powerful forward Moriarty, whose impressive ball carrying and tough tackle technique saw him play an important role for Wales in both New Zealand last summer and in November, begins the game from the off with Taulupe Faletau out injured.
It means he goes up against Parisse, Italy’s iconic leader. It’s an individual battle which could go a long way to deciding which team comes out on top at the Stadio Olimpico.
“I have had a few opportunities over the last season and a half and I am enjoying myself,” Moriarty said. “I feel comfortable in the team and in the squad and there is a lot of competition in the back row. It is making me a better player.
“Whether Toby is fit or not, I know I have to give my best, no matter what position I am playing in. His coming back to full fitness will be great for the team. Whether that means I am not going to play, I am not sure. Every game I play I give everything I’ve got.”
Wales will know full well they’ll have to stop Parisse if they are to keep Italy quiet and start their Six Nations with a bang. Their last two games with the team in blue have seen Wales record convincing victories, but the 2017 encounter could end up being a lot tighter.
“I played against Parisse in the last Six Nations when I came off the bench and it was a great experience to play against such a big name,” Moriarty added.
“He has been around for quite a while playing for Italy from a young age and he has plenty of caps and experience. When I watched the Six Nations, he was always one of the stand-out players for Italy and you cannot take away the fact he is pure quality.
“I look forward to the challenge. He is one of their man ball-players with his carrying and skills. He is a big man in their team and we have done a lot of analysis on him.”
