Welsh rugby derbies need experienced referees, says Blues coach Danny Wilson

Cardiff Blues coach Danny Wilson says Pro12 derby matches should be controlled by experienced referees.

Blues felt Lloyd Linton should have had awarded them a penalty try in their 26-15 defeat by Scarlets.

Wilson did not blame the decision for his team's loss, but felt there were a number of "talking points" during a match which also saw Scarlets' Aaron Shingler controversially sin-binned.

"These are huge games - they are games for experienced referees," he said.

"In saying that, young referees need their opportunities, but tonight I don't want to get too far away from crediting the Scarlets and we've got to look at ourselves.

"That's the reason the result has gone the way it's gone."

"I agree there were plenty of talking points. Plenty of match-affecting talking points, but I'm not going to take away from the Scarlets."

Blues were trailing 21-7 when they had a series of attacking scrums which started in the 31st minute and continued until half-time.

Mr Linton showed yellow cards to Blues prop Taufa'ao Filise and Scarlet Wyn Jones, but Wilson felt his side were not rewarded for their set-piece dominance.

"We've had four penalties awarded to us for a dominant scrum and we get a player yellow carded, which I don't understand, and we don't get a penalty try," said Wilson.

"In fact there were four penalties and a free-kick, I think.

"We had scrum dominance all night. You go there hopefully with dominance to come away with the seven points, we didn't get it.

The result saw Scarlets overtake Blues in the Pro12 table after a fourth consecutive win.

Scarlets head coach Wayne Pivac felt that the decision to award the initial scrum was incorrect, as was Shingler's yellow card when he appeared to be impeded by his brother, Steven.

"Clearly he was tackled without the ball and the wrong player was sin-binned," said Pivac.

"We'll do what we normally do and go through the game and review our performance and we review the officials every week and we're encouraged to give feedback and we'll do that."
