Wayne Pivac’s side travel up the M4 hoping to bounce back from successive defeats to Ireland and France respectively. Despite facing a strong England outfit Moriarty is confident Wales can make their mark.
“We know if you don’t match England physically then you’ve got no chance,” said the Dragons back-rower.
“As a pack and back-line we have to go and meet them, especially in their back yard. That’s what we’ll be looking to do. They pride themselves on having a big and physical pack with a few big backs so we know what’s coming.
“It’s no different to any other time we have played against them. It’s always the same when you play away from home. You want to put your marker down early and keep the crowd quiet, especially at Twickenham.
“That’s a big thing for us. It’s great when we play at home as we get the crowd on our side and it’s the same for them when they’re in their own backyard.
“It’s not nice when someone comes in and ruffles up your feathers. Getting stuck into people physically is my bread and butter so I’ll definitely be trying to do that from the start.”
Despite a disappointing start to their Six Nations campaign Moriarty insists Wales aren’t far off where they need to be. And the physical back-rower can’t wait to get stuck into a physical England pack.
He said: “It’s disappointing when you lose. No one wants to lose.
“I think France was a game which could have gone either way with a bounce of a ball and the interception pass which gave them a 50-metre try. There were quite a few positives so we’re looking to build on that.
“For certain people and the way they play there might not be that sort of rivalry, but for me every time I go on the pitch it’s personal whether you’re playing Italy, France, Ireland or Scotland. It might be a little bit more for England because we know how much it means to everyone.
“No one wants to see us lose. We want to win every game. It doesn’t happen every week, but we’re looking forward to it.”
