Priestland, 23, has won plaudits aplenty for the manner with which he has filled in for Jones at club level when the 95-cap No. 10 has been away on international duty.

The Scarlets youngster has already been mentioned as a future Wales star by boss Warren Gatland and he has the perfect chance to strengthen his claim with festive period clashes against the Ospreys and Dragons.

And Priestland is adamant he will grab the chance with both hands as he looks to force his way into Gatland’s RBS 6 Nations reckoning.

“I don’t want Steve to be injured but if it is an opportunity for me, I have to take it,” said Priestland.

“It is never good when one of our best players is injured especially over such an important period.

“Christmas is always a busy period in Welsh rugby and if you are playing well for your region you are going to be there or thereabouts for Wales.

“When you are playing against fellow Welsh regions you are playing against guys who have either got the national shirt or are close to it.

“But ideally I would just like to concentrate on what is happening down at the Scarlets.

“My main priority is to try and get as many victories as we can with the Scarlets.

“We have momentum and are in a good position in the Magners League and the Heineken Cup.

“I have played quite a lot this season and am quite comfortable with the way I have performed.

“I am probably playing the best rugby of my career with the Scarlets at the moment.”
