Biggar kicked 23 points, a Welsh record in a single World Cup match, as Wales helped knock hosts England out of the tournament at the pool stage in 2015.

“It is never easy,” he said. “When you see it on paper, England away at Twickenham, it sounds maybe harder than it is.

“People remember the 2015 win which was incredible but apart from that I have not got that good a record there.

“We have lost a few games but have never been steamrollered there like some other sides.

“The games have been tight, because over the last 10 years, the teams have been relatively evenly matched and home advantage has just favoured sides.

“I don’t expect it to change too much this weekend in terms of it being tight. England will start as favourites but Wales can go there with more confidence and opportunity than people are giving them.

“It is not an easy place to play your first game at 10 but what a brilliant place to go and play. What a game to make your first international start.

“Ioan will be excited but there will be nerves. I am sure Ioan has the ability and temperament because in games like this you have to be mentally strong to tackle these challenges.

“Ioan is an excellent rugby player. The coaches will tell him to play his own game. They will be looking for him to control the game from the off and he has got all the attributes to do that.

“He will know starting a game is different to coming off the bench when you are losing and chancing your arm with nothing to lose.

“It is a different challenge for him this weekend but I am sure he will be fine.”
