ROSS Moriarty has pledged to “show everyone what I can do” against Fiji to secure a permanent return to the Wales XV.

The Dragons number eight had to be content with the role of impact sub in the wins against Georgia and Australia after losing out to Rodney Parade teammate Aaron Wainwright.

Moriarty is back in the XV for tomorrow’s clash with the Fijians in Oita, with victory securing a place in the quarter-finals and putting Warren Gatland’s men on the brink of sealing Pool D top spot.

The 25-year-old starts at number eight with Josh Navidi shifting to blindside and James Davies getting a shot at openside in place of Justin Tipuric.

Moriarty has started in 29 of his 36 Test appearances and after being a key figure in the Six Nations Grand Slam in determined to reclaim his spot.

Campaign Series:

“I’ve got the start and I am really excited for it. I’ve been working hard in training, and it has been great competition in the back row and we are all fit and firing,” said the 2017 Lions tourist, who can play 6 or 8.

“We know it’s going to be tough. It won’t be easy, but we have been working hard in the last week and we’ve done our analysis.

“We will have to close Fiji down in defence, and in attack we want to get points on the board.

“We know they have some great individuals, but so do we, and we are just going to make sure we put everything out there and do the job.

“I was fortunate to play for Gloucester’s A team against Fiji A when I was 18, which was a bit of an eye-opener.

“To be on this stage now makes it even bigger, and I am excited to get out on the pitch, get a start and show everyone what I can do.”

Moriarty’s response to being dropped to the bench won the praise of head coach Gatland.

“He’s been positive, vocal at training and he’s been what you expect of someone who knows they are disappointed but also knows what their role is in the team, which is to help the side prepare. That’s all I can ask as a coach,” said Gatland.

Wales have tinkered with their back row but retain Navidi, who has become a key figure in the side after having to battle hard for a shot under Gatland.

There were question marks over the versatile Cardiff Blues back rower’s size but the 28-year-old has proved to be tough as teak on the Test stage.

Campaign Series:

"He runs hard, tackles hard, does the basics well and doesn't make many mistakes," Gatland said.

"I remember speaking to John Mitchell (England defence coach) after we played England at home, and he said that the England boys have a lot of respect for him as a player.

"That to me is recognition of quality.

"A few years ago - I think it was one of Josh's first games when we played the All Blacks - and Steve Hansen said: 'where did you get that number seven from?'

"We are very lucky in that department. We have some real quality loose forwards who are all capable of doing a job, and there is some real competition there."
