Wales flanker Ross Moriarty is relishing his battle with England new boy Teimana Harrison at Twickenham on Sunday.
Both players will look to put down markers before demanding summer tours, with Wales tackling the world champion All Blacks three times in New Zealand next month, while England face Australia in Brisbane, Melbourne and Sydney.
Harrison makes his Test debut this weekend, and although rival blindside Moriarty wins a sixth cap, it is only the second time in a Wales starting XV.
"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."
St Helens-born Moriarty, whose father Paul and uncle Richard both played for Wales, underlined enormous potential when he featured off the bench and scored two tries during Wales' RBS 6 Nations finale against Italy two months ago.
The 22-year-old is part of Wales' considerable back-row riches, and even though Sam Warburton and Justin Tipuric are absent this weekend, they can still parade a breakaway unit of Moriarty, Dan Lydiate and Taulupe Faletau.
"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."
