Wales flanker Ross Moriarty looking to take on Teimana Harrison

Wales flanker Ross Moriarty is looking forward for a confrontation with newly picked England's Northampton flanker Teimana Harrison when both the teams meet each other at Twickenham on Sunday.

Harrison has been handed a debut by England coach Eddie Jones in the blindside in the place of Chris Robshaw while his counterpart Moriarty will make a start in Wales XV only for the second time after making five appearances already.

Both the players will look to impress their respective coaches ahead of a crucial summer season where England will head to Australia for a three-Test tour while Wales will travel to New Zealand.

Recalling his first appearance in English rugby when he played for Gloucester Academy against Harrison's Northampton, Moriarty said he was impressed with the 23-year-old's tackling skills.

"I played against him in my first game for Gloucester Academy against Northampton. He is a very powerful ball-carrier, and he will test me this weekend," Moriarty said.

"I came off the bench in the last 20 minutes of that game. It was my first experience of English rugby, and it was tough.

"He was one of their main players - a very powerful ball-carrier and tackler. He was here, there and everywhere, and he is still the same sort of player.

"I think I ran over him on a one-on-one. He may have been a bit more tired, while I was fresh off the bench, but it was a good night for me."

Wales will be missing two of the key players in Sam Warburton and Justin Tipuric and Dan Lydiate will be leading the team on Sunday with lock Alun Wyn Jones returning from injury.

The 22-year-old believes the game on Sunday will be a challenge for the Wales team as they prepare themselves for a crucial tour of New Zealand.

However, the Gloucester flanker feels training with the likes of Taulupe Faletau will benefit him in becoming a better player.

"This is going to be a good test for us on Sunday, going into the first Test with the All Blacks on June 11," Moriarty added.

"We are going to try to play at the intensity that we will need against New Zealand, so it's a good opportunity to test ourselves.

"It is really competitive in the back-row. Even without Justin Tipuric here, we have three British and Irish Lions Test back-rowers.

"It is hard to break a mould that has been there for a few years, but it's great for me to learn off them, watch how they train and pick up little things off each of them to make me a better player.

"Toby (Faletau) is one of the best, if not the best, number eights in the world, and he is only 25 years old.

"It's nice to be able to train with him, watch what he does and try to replicate some of the things he does and add to my game."
