Hook and Henson will continue to swap roles

The Wales starlet impressed at fly-half in the 50-24 win over the Scarlets, with Gavin Henson at inside centre.

Henson had seemed to struggle at stand off in the 30-24 loss at the Blues, but the players will continue to rotate.

"We'll keep switching them in different parts of the field, we're still in the early stages of experimenting," Holley told BBC Sport Wales.

"I think that's the way to go if they continue to play together - but they also have their positions under threat from the likes of Shaun Connor."

Whilst Hook again stole the headlines, the Ospreys' muscular pack - led by man-of-the-match Ryan Jones - paved the way for their west Wales derby win.

Ryan has been immense, he's finding form after a long lay-off Sean Holley on Ryan Jones

"It's no secret that we have a real physical edge at the moment," said Holley.

"There's a lot of size out there, the set piece is improving all the time, and we're complementing that behind.

"Ryan has been immense, he's finding form after a long lay-off.

"A lot of our improvement is down to the competition in the squad, with guys like Filo Tiatia really pushing things."

Jones himself was delighted with the thumping victory over their rivals from Stradey Park.

"It was a hell of a game for Boxing Day, playing in front of over 20,000 at the Liberty Stadium is what it's all about," the number eight told BBC Sport Wales.

We just wanted to win it more than they did Shane Williams on the Scarlets win

"That sort of occasion and the excitement of the game is great for us and for the Magners League."

Ospreys wing Shane Williams feels that the performance against the Scarlets was a backlash after the defeat at the Blues.

"The boys were out to prove a point after the disappointment at the Arms Park and they did with a special performance," he said.
