Cardiff chief executive Robert Norster looked like the cat with the cream after watching rugby league convert Iestyn Harris steal the show on his first start in the 15-man game.

Cardiff eclipsed Glasgow 46-7 in their Heineken Cup clash at the Arm's Park and afterwards Norster declared: "I've never seen a debut like that in my life."

"Signing Iestyn from rugby league was a big move for him and for the club and that show has proved us right," said Norster. "Now he can go on and help this club achieve great things - and hopefully Wales as well."

After announcing his presence with a club Heineken Cup record 31 points - including three individual tries - Harris acknowledged that he had put himself under even greater pressure.

"Next week they'll probably expect me to score four tries," he smiled. "But I have to thank the forwards. They were fantastic and laid the platform to enable us to play like that.

"I wasn't too nervous - luckily, I'm not that sort of person. I believe you have to treat every game the same, whether it's your first or your last.

"But I really enjoyed it. I can't wait to begin training again ready for the next match."

Harris, with just 40 minutes' experience as a replacement behind him, did not agree that his solo performance was the stuff of dreams.

"I came down here to learn the game," he said. "I didn't dare to dream too much. I know I've still got a long way to go."

Norster agreed. "He's still got his feet on the floor - dancing on the floor, on occasion - but he's a level-headed guy and I can't think of a better man to take this forward."

Cardiff coach Rudy Jubert was pleased with the overall team display, which also featured a hat-trick for another former rugby league star, winger Anthony Sullivan.

"A lot of things that we've been working on in training came together out there," said the South African. "The forwards were superb and it must have been a joy for the backs to get quality ball like that."

Richie Dixon, who has to pick up his Glasgow team for the reverse fixture next weekend, said: "We were forcing the game, trying to squeeze things out when we could have been sitting back and the points would have come.

"When you try to force things, individual discipline goes.

"All credit to Cardiff and Iestyn, but his tries all came from set pieces and the man-marking was unacceptable. We can address that."
