Wales' teenage rising star George North will go into Sunday's RBS 6 Nations clash against Scotland being hailed as "a superstar of the game".

North: Has broken a world record

Winger North's debut Six Nations campaign, despite being just one game old, has already seen him break a world record.

His try against Ireland in Dublin last weekend set a new mark of 10 for most Test touchdowns as a teenager, surpassing the previous best set by Argentina wing Gustavo Jorge.

Given that Jorge scored six of his nine tries against Brazil, while more than half of North's tally came against South Africa, England, Ireland and Argentina, it underlines what a startling impact he has made on international rugby.

Wales coach Warren Gatland described the 19-year-old's display last Sunday as "absolutely world-class," a performance highlighted by a destructive midfield break and brilliant one-handed offload that set up centre Jonathan Davies' second try.

"I was behind George when he gave the offload for Jon Davies' second try," Wales fly-half Rhys Priestland recalled.

"I had to stop because I couldn't believe what I had just seen! He is a superstar of the game, and he is only 19.

"My first experience of George was when he started training with the Scarlets at the start of last season.

"I hadn't met him before, and I remember we were doing gym testing. This guy was just so much stronger than anyone else in the squad, and I said to him afterwards had he done much with his time off.

"He said he'd had exams, and I said were they university exams, and he said: 'No, A levels!'

"I play in the same team as him all the time, and he doesn't seem to stop surprising me.

"I had heard of him when he was playing for Llandovery before he joined the Scarlets, and everyone said he was going to be a good player, but I had no idea he was so young and how good he was going to be.

"He is someone who concentrates on the basics. He tries to get over the gain-line, he runs hard and he has good support lines."

North is currently the star attraction in a Wales back division unchanged from Dublin after they outscored Ireland 3-2 on tries and created numerous other chances.

A home win this weekend would leave Wales needing one more victory - against England at Twickenham later this month - to secure a 20th championship Triple Crown.

But Priestland believes there is room for improvement, adding: "I wouldn't say it was as good a performance as when we played Ireland in the World Cup, or South Africa.

"But it was the first game of a tournament and we hadn't been together for a while. It is a good platform for us to build on, now.

"Everyone has really bought in to the way we want to play. There are no egos, just everyone wanting the team to do well.

"There are areas of the game where we can improve, and hopefully we will keep progressing as the tournament goes on. We will keep working hard.

"The foundations are there for us to build on. No team is ever the finished article, so you always keep striving to get better. As a group of players we are all eager to learn.

"It was pretty nailbiting stuff last Sunday, but we didn't hit the panic button. We stuck to our patterns, and fortunately we got the penalty to win it in the end.

"At half-time, it was a bit like the Samoa game in the World Cup where we were up against it, but we didn't panic.

"Some days you get decisions, some days you don't, and on another day perhaps we wouldn't have had the penalty at the end, but we showed a lot of character and did everything in our power to make sure the game went our way."
